What Should We Pay Attention To When Using Lipo Batteries

What Should We Pay Attention To When Using Lipo Batteries

Since the advent of lipo batteries, they have developed rapidly due to their excellent performance and unparalleled advantages, and have been widely used in various scenarios, quickly occupying many fields. But the way most people use and maintain lithium battery packs is not very clear. In order to use lithium batteries better and more safely, lipo battery suppliers will show you what to pay attention to daily.

1. Precautions for lipo battery charging

Lithium batteries are strictly prohibited to be charged from the discharge terminal, and must be charged from the charging socket with the matching special charger. When the charging indicator bar on the charger stops scrolling, please remove the charging plug in time to avoid overcharging the battery.

2. Notes on discharge

The lipo battery pack has an overcurrent protection function. When the use current of the electrical equipment exceeds the maximum output current of the product, the overcurrent protection circuit will act and make the electrical equipment appear to be unable to work normally.

3. For newly purchased lipo batteries

The newly purchased lipo battery has a little power, so users can use it directly when they get the battery, and recharge the remaining power. After 2 to 3 times of normal use, the lithium battery activity can be fully activated. Here is a special reminder: Don’t misbelieve the rumors from the salesperson or the Internet, the new lipo battery needs to be activated for up to 12 hours when it is first used.

4. When charging the lipo battery

Lithium batteries have no memory effect and can be charged as they are used, but it should be noted that lithium batteries cannot be over-discharged. Over-discharge will cause irreversible capacity loss. When the machine warns that the battery is low, it will start charging immediately.

Do not use it in a hurry after charging. In daily use, the newly charged lipo battery should be put on hold for half an hour, and the charging performance is stable before use, otherwise it will affect the battery performance.

5. Lipo battery use environment and maintenance methods

When not in use, such as laptop lithium batteries, be sure to take out the batteries and store them in a dry and cool place. Note that the charging temperature of the lithium battery is 0 ℃ ~ 45 ℃, and the discharge temperature of the lithium battery is -20 ℃ ~ 60 ℃.

Avoid frequent overcharging. Overcharging will cause the internal temperature of the battery to rise to a high level, which is harmful to the lithium-ion battery and charger. Therefore, a full charge is enough to turn your lithium battery into a small bomb.

The battery is a consumable product, and its life span is fixed (the number of charging and discharging is usually 300-500 times), so mastering the correct method of use is the secret of battery life extension.

6. Battery maintenance for the correct use of lipo battery packs

Charging: The safe working voltage range of lipo battery is 2.8~4.2V, lower or higher than this voltage range, the lipo ion in the battery becomes very unstable and even causes accidents. In order to ensure that the battery is in a safe range, a special charger is required.

Lithium batteries need to be charged and discharged every three months to restore their original performance.

Before using the lipo battery, check whether it meets the requirements of the load. Using it under conditions that cannot meet the load requirements or high current (over 1C) will damage the battery or shorten its life.

Avoid frequent use in high or low temperature environments. It is best to be at room temperature, as temperature has a great influence on the characteristics of lithium batteries.

7. How to store lipo battery without long-term use

Lipo batteries should be charged with 50%~80% of electricity if they are not used for a long time, and they should be taken out of the instrument and stored in a dry and cool environment. The batteries should be recharged every 3 months to avoid excessive storage time and battery self-discharge. Too low, resulting in irreversible capacity loss. The self-discharge of the lithium battery is affected by the ambient temperature and humidity. High temperature and humidity will accelerate the self-discharge of the battery. It is recommended to store the battery in a dry environment between 0 ℃ and 20 ℃.

Lithium Battery VS Lithium-Ion Battery: Which Is Better?

 

Batteries are an incredible resource today. They power mobile phones, wireless automatic vacuum cleaners, and all different types of cameras. Batteries have many different uses and can be used for many different purposes, but we hear more than lithium batteries and lithium ion batteries. You may have to make a decision about these two different battery types in the past, but do you really know what they are?

In order to make the most of batteries, it is best to learn about lithium and lithium-ion batteries of various shapes and sizes, such as 95Wh batteries and 190Wh batteries. We will explain everything you need to know about lithium batteries and their lithium-ion cousins, including their working principles, materials, and even methods of recycling old batteries. Then, we will list the important differences between lithium batteries and lithium ion batteries so that you can wisely decide which battery to use.

What is a battery?

To understand the similarities and differences between lithium batteries and lithium-ion batteries, you need to have a basic understanding of the composition of the battery and how it works. All batteries are made up of the same three basic components; anode (negative-side), cathode (positive+side) and some kind of electrolyte. When the cathode and anode of the battery are connected to the circuit, a chemical reaction occurs between the anode and the electrolyte.

The electrons flow from the anode through the circuit, then from the cathode back and trigger another chemical reaction. These reactions continue until the material is consumed, at which time the battery no longer produces electricity. Both lithium batteries and lithium-ion batteries generate portable electrical energy in this way and can be used to power a variety of different devices and circuits. The battery is a very useful component. It allows us to use all kinds of luxury goods. Without them, we would have to start the car manually, and the mobile phone would still be all hung on the wall.

What is a lithium battery?

Lithium batteries are primary batteries, which means they cannot be charged once they are exhausted. They use metallic lithium as the anode. Lithium batteries have a higher charge density, which means they have a longer service life than other batteries and can hold more power. Depending on its design, a lithium battery can generate a voltage of 1.5 to 3.7 V. The metals used in lithium batteries are highly reactive, and pure lithium will immediately react with water or even moisture in the air.

Lithium batteries are used in many electronic devices, from electric toy cars to large vehicles. Although their high power capacity makes them very useful, the fact that they cannot be charged easily or even safely means that many companies are starting to look for alternative products. The disposable batteries that many of us have at home are not very good for the environment, which is why many people and companies decide to use lithium-ion batteries.

What is a lithium ion battery?

Lithium-ion batteries are secondary batteries, which means they can be charged and reused. These batteries are very popular today. Without them, our daily lives would be very different. Your laptop, mobile phone, tablet, and camera all rely on lithium-ion batteries to keep them working because these rechargeable batteries are very effective. The electrodes of lithium-ion batteries are made of lithium and carbon, making them much lighter than other rechargeable batteries.

Lithium-ion batteries are also excellent in maintaining power, and only about 5% of their power is lost when they are not used every month. Another advantage of lithium-ion batteries is that they have no memory effect. Ever remember someone told you that you need to fully discharge the battery before inserting it to charge it? Not suitable for lithium ion batteries. These excellent rechargeable batteries can handle hundreds of charging and emptying before they deteriorate.

Lithium-ion batteries are inherently very complex, not as simple as ordinary old lithium batteries. Among lithium-ion batteries, you will find multiple lithium-ion batteries that store and provide electrical energy. However, lithium-ion batteries also have other components. A small computer in the battery can monitor and adjust the temperature, voltage, and battery charging status from inside the device. This compact system is essential to keep the battery working properly, and it also causes these rechargeable batteries to suffer 5% power loss every month.

What is the difference between lithium batteries and lithium ion batteries?

The biggest difference between lithium batteries and lithium ion batteries is that lithium batteries have a single-cell structure, which means they are disposable and cannot be charged once they are used up. On the other hand, lithium-ion batteries can be used again and again, they are rechargeable, and can be charged and emptied hundreds of times.

If they sit on idle shelves, the life of lithium batteries will actually be longer. Lithium batteries can be used for 10 to 12 years when kept charged, while lithium ion batteries can only be used for 2 to 3 years. You may not know that these two batteries are actually not the only types of lithium batteries you can get.

Although lithium-ion batteries seem to be better, especially from a waste point of view, there are still some characteristics that make lithium batteries very useful. They have a higher energy density than lithium-ion batteries, which means they have more charge than their size. Lithium batteries can provide electricity with a single charge, even if this is their only charge. Unfortunately, there is no safe or effective way to charge lithium batteries, which is why lithium-ion batteries were invented in the first place. In addition, lithium batteries are cheaper and easier to manufacture, which means lower purchase costs.

Lithium battery and lithium ion battery: which is better?

Batteries have many different uses, because anything that requires a portable power source needs them. The better battery type depends entirely on your use, which is why both batteries are still produced and used worldwide today. Modern life relies heavily on portable power batteries, which are essential for our personal electronics, automobiles and transportation and even our medical care.

For devices that must extend battery life, lithium batteries are a better choice. Examples include watches, film cameras, pacemakers, hearing aids, remote controls, calculators and smoke detectors. All of these items require a long-lasting power source, and do not need to be plugged into the mains all the time, so lithium batteries are an ideal choice.

The more favorable conditions of lithium-ion batteries require frequent charging for ease of use. The lithium-ion battery in a mobile phone can usually be used for about a day, but you can charge it every day for many years without losing too much functionality. Devices such as notebook computers, digital cameras, solar storage devices, portable power packs, and any kind of wireless technology rely on rechargeable lithium-ion batteries to function. Because of their frequent use, they need the ability to charge without replacing parts.

Do not expose both types of batteries to high temperatures, as this may cause permanent damage or even danger. Store the battery in a cool and dry place at normal room temperature.

Better battery, better world

Lithium batteries and China Li-ion batteries are both very useful and have made great contributions to most people's daily lives. From life-saving medical technology to remote control toy cars, their applications are endless. It is hard to imagine the modern world without them. Both types of batteries provide a portable power source, and they provide charge to compatible circuits no matter where you are.

The difference between lithium batteries and lithium ion batteries is that one battery cannot be charged (primary battery) while the other can be charged (secondary battery). In addition, the shelf life of lithium batteries is four times that of lithium-ion batteries, and they are cheaper and easier to manufacture. Before the emergence of some new power technologies, lithium-ion batteries will always be the best choice for the electronic products we use every day. This applies to your mobile phone, digital camera, and even electric toothbrushes.

On the contrary, it is best to use lithium batteries to power the items we use to maintain power for a long time. Regardless of safety features such as medical pacemakers or smoke alarms, lithium batteries are the first choice because of their longer service life. And, although we want to point out that this situation is very rare, it is well known that lithium-ion batteries can catch fire and explode, but fortunately, lithium-ion batteries do not have this function.

What Is the Difference Between Lithium Battery and Lithium Ion Battery?

 Lithium batteries are disposable batteries, and lithium-ion batteries are rechargeable rechargeable batteries! Lithium-ion batteries generally use lithium cobalt oxide as the positive electrode and carbon as the negative electrode. The electrolyte is filled in between to form a channel for ion dissociation, and a separator is used to separate the positive and negative electrodes. Short circuit. When charging, due to the action of the electric field, lithium ions swim out of lithium cobalt oxide, free in the electrolyte, pass through the pores in the separator, and reach the negative electrode and react with carbon to form lithium carbide; the discharge process is opposite, and the lithium ions return to the positive electrode. It is the charging and discharging process of lithium-ion batteries.

Lithium batteries generally refer to primary lithium batteries, mainly lithium manganese and lithium iron batteries. Lithium-ion batteries are mainly lithium secondary batteries. The rechargeable batteries mainly include lithium manganese oxide, lithium cobalt oxide and lithium iron phosphate batteries. Lithium ion power batteries are mainly suitable for power batteries. The main feature is that the battery can High-power discharge, long battery cycle life, etc., such as lithium iron phosphate lithium ion battery. Lithium batteries use metal lithium as an electrode to generate electric current through electron transfer. Because they are prone to produce dendrites and cause explosions, they are no longer in use. Lithium batteries are primary batteries. Lithium-ion batteries are charged and discharged by the transfer of lithium ions, and mainly use lithium-doped metal oxides as electrodes.

Lithium Ion Battery 36V is a rechargeable secondary battery. 1. Lithium primary battery is also called primary lithium battery. It can be discharged continuously or intermittently. Once the electricity is exhausted, it can no longer be used, and it is widely used in low-power electronic products such as cameras. The self-discharge of lithium primary battery is very low and can be stored for 3 years. It will be better if stored under refrigerated conditions. It is a good way to store lithium primary batteries in a cold place. Note: Lithium primary batteries are different from lithium ion batteries. Lithium primary batteries cannot be recharged, and charging is very dangerous! Lithium battery principle--Lithium metal batteries Lithium metal batteries often use manganese dioxide MnO2 as the positive electrode material, and use metal lithium Li or its alloys As the negative electrode material, a battery using a non-aqueous electrolyte solution. The chemical equation of the discharge reaction is Li+MnO2=LiMnO2.

Rechargeable Li-ion Cells are also called secondary lithium batteries. It can be stored for more than half a year at 20°C. This is because its self-discharge rate is very low and most of its capacity can be recovered. Lithium battery principle-Lithium ion battery Lithium ion battery often uses lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and the battery using non-aqueous electrolyte solution. The chemical equation of the positive electrode when charging is LiCoO2==Li(1-x)CoO2+XLi++Xe- (electron), the chemical equation of the negative electrode is 6C+XLi++Xe- = LixC6, the total reaction of the battery is LiCoO2 when charging +6C = Li(1-x)CoO2+LixC6.

The self-discharge phenomenon of lithium batteries, if the battery voltage is kept below 3.6V for a long time, it will cause the battery to over discharge and destroy the internal structure of the battery and reduce the battery life. Therefore, long-term storage of lithium batteries should be recharged every 3 to 6 months, that is, charged to a voltage of 3.8 to 3.9V (the best storage voltage of lithium batteries is about 3.85V), and it is advisable to maintain the discharge depth at 40%-60% , Should not be full. The battery should be stored in a dry environment at 4℃~35℃ or in moisture-proof packaging. Keep away from heat sources and do not place in direct sunlight. Lithium batteries have a wide application temperature range. They can still be used outdoors in winter in the north, but the capacity will be much reduced. If they return to room temperature, the capacity can be restored.

Misunderstandings about Lithium Battery Discharge

 "The more the lithium battery is discharged, the greater the loss of the battery," said Tom Hartley, a professor of electronic engineering at Aikeron University who helped NASA study extending battery life. "The more fully charged the battery is. , The loss of the battery will be greater. The lithium battery is in the middle of the charge, so the battery life is long."

First of all, too high and too low power states have an adverse effect on the life of lithium batteries, and the number of charge and discharge cycles is of secondary importance. In fact, the number of rechargeable cycles marked on most of the electrical appliances or batteries sold is based on 80% discharge as a benchmark test. Experiments show that for some laptop lithium batteries, the battery voltage often exceeds the standard voltage by 0.1 volts, that is, from 4.1 volts to 4.2 volts, then the battery life will be halved, and if it is increased by 0.1 volts, the life will be reduced to 3 One part; the long-term low or no power state will make the resistance of the battery to the movement of electrons become greater and greater, thus causing the battery capacity to become smaller. NASA set the battery power consumption on its Hubble Space Telescope at 10% of the total capacity to ensure that the battery can be repeatedly charged and discharged 100,000 times without needing to be updated.

Second, temperature also has a greater impact on the life of lithium batteries (mobile phones and other small electronic devices can ignore this point). The environment below freezing point may cause the lithium battery to burn out when the electronic product is turned on, while the overheated environment will reduce the battery capacity. Therefore, if the notebook is used for a long time without removing the battery from an external power source, the battery will remain in the high heat discharged from the notebook for a long time. More importantly, the battery will be in a state of 100% power for a long time and will soon be scrapped.

From the above, we can sum up the following points to ensure the capacity and life of Lithium Ion Rechargeable Battery:

At present, most electronic products use lithium batteries. Since their introduction in 1990, lithium-ion batteries have developed rapidly due to their excellent performance and have been widely used in society. Li-ion Battery Company It has also been developed on a large scale. There is no need to charge the lithium battery to 100% full, let alone run out of power. When the situation permits, try to keep the battery's capacity near the half-full state, the smaller the range of charging and discharging, the better;

The factory design of the general Chevy Volt electric car is to force the battery to be maintained at 20% to 80%, and the built-in battery of the Apple laptop may also use this method (including some other laptops and electronic products) to make the battery's capacity The number of charge and discharge cycles increases.

Lithium Ion Rechargeable Battery

Do not use Li-ion Battery (especially laptop lithium battery) for a long time when the device uses an external power source. Even if your notebook has good heat dissipation, 100% of the long-term power is equivalent to the murder of lithium batteries.

1. If you use an external power supply to power your laptop for a long time, or the battery power has exceeded 80%, immediately remove the battery of your laptop. You don’t need to fully charge the battery at ordinary times. You can charge it to about 80%; adjust the operating system power supply Option, adjust the battery level alarm to more than 20%. Normally, the battery level should not be lower than 20%, and the battery should be charged before it drops to 20%;

2. For small electronic devices such as mobile phones, immediately disconnect the power cord (including the USB port for charging function) after charging, and it will continue to damage the battery; charge it frequently, remember to charge it, but you do not have to fully charge the battery;

3. Regardless of whether it is a notebook or a mobile phone, etc., do not let the China Li-ion Battery run out;

4. If you are going to travel, fully charge the battery, but please remember to charge the appliance at any time when conditions permit. For battery life, do not wait until the battery is dry.
