lithium ion battery 18650 price

　　At present, electric vehicle batteries are mainly lithium ion battery 18650 price and lead-acid batteries. lithium ion battery 18650 price are receiving more and more attention in the market due to their advantages such as high energy relative density, small size, light weight, and long life.

　　Incorrect battery charging methods may damage lithium-ion batteries and reduce lithium-ion battery life. For example: if the lithium battery is overheated during charging, the electrolyte interface (sei) module will begin to decompose and generate heat → the electrolyte → the positive electrode will begin to thermally decompose, causing gas evolution and causing the temperature to rise rapidly → in more severe cases, the battery may explode. Lithium battery charging overvoltage, lithium metal material separation, solvent electric vehicle lithium battery price is oxidized, temperature rise, leading to polarization, rechargeable battery ignition, engineering explosion.

　　Let’s discuss these issues regarding the charge of lithium-ion batteries.

　　1. How to prevent overcharging and power damage of lithium ion battery 18650 price

　　Since lithium ion battery 18650 price have a high mechanical energy ratio, operating rechargeable batteries cannot cause excessive charging or functional loss. Excessive sewage discharge will cause

　　Although lithium ion battery 18650 price now include maintenance panels that have been used, under normal circumstances, the chance of power loss is very low. However, without more precise maintenance, there may still be a risk of power loss under the following circumstances: sex.

　　1. The access panel fails.

　　2. The service life of lithium battery is 10%/month).

　　Therefore, if there is a more accurate intelligent management system to detect and let buyers know the first moment of battery charging, it is the best way to solve the problem of lithium-ion battery charging.

　　2. How to control the amount of current

　　Taking a single lithium battery as an example, its battery charging methods include constant current power supply and DC power supply battery charging. Although charging a large current battery will shorten the battery charging time, it will also reduce the number of battery cycles and volume, so a suitable constant current battery should be selected. The current value is used to charge the battery.

　　The figure below shows the relationship between the battery charge and the battery power of lithium ion battery 18650 price with different current capacities. The figure below shows that after the next battery charge cycle 500, the charge capacity of the low-current battery exceeds the charge capacity of the high-current battery.

　　How to control the working standard voltage of constant current source battery?

　　As a kind of high-efficiency energy-density rechargeable lithium battery, overcharging will cause great damage to the lithium battery and may cause the expansion and leakage of the lithium battery. What is even more serious is that it will cause fire accidents and engineering explosions. Over-rechargeable batteries easily cause the electrolyte solution in the rechargeable lithium battery to respond quickly, and the service life of the rechargeable lithium battery is shortened. Therefore, accurate constant current battery charging value is very important for lithium ion battery 18650 price.

　　For sufficient battery charging, ensure that the accuracy of the DC power supply value and the working terminal voltage value is less than 1%. Taking lithium cobalt metal oxide rechargeable batteries as an example, it is best to be as close as possible, but not as close as possible. This high-precision working voltage battery charging method can reduce the melting of cobalt, stabilize the layered structure of licoo2, and make it filler Does not produce changes, improves the function of the circulatory system, and maintains high capacity.

　　Therefore, even a small overvoltage may cause two changes: (a) the initial volume of the battery is increased; (b) the battery cycle life is reduced.
