What are the reasons why life of lithium-ion battery capacity in winter?

About lithium-ion batteries, there is currently no clear theory to support internal resistance, discharge platform, life and capacity of lithium-ion batteries at different temperatures. Related calculation formulas and mathematical models are still in the exploration stage. In general, lithium ion batteries are not sensitive to 0-40 degrees Celsius.

However, once the temperature exceeds this range, the life and capacity of the lithium-ion battery will decrease. There is no way to quantify, because lithium-ion batteries are too active, consistency is the biggest problem. Even with the same batch of products, the same material, the same process will also have very different performance.

Made a large number of tests, the low temperature performance of lithium-ion batteries of different materials is also different. At present, the hottest lithium iron phosphate is the worst at low temperatures. At -10 ¡ã C, our product release capacity is 89% of the maximum capacity.

It should be relatively high in industrial, and the output capacity at 55 ¡ã C can reach 95%, and attenuation at lower temperatures is still small. This is also a product to be tested. Everyone understands that the quality of normal processing lines is much higher than the quality of general processing lines.

Lithium manganese acid, cobalt lithium and tri-dielectric compounds at high temperature performance is better, but also subject to restrictions. At present, the industry's brake-free phosphate has high safety performance, high temperature performance, and actually battery activity is not as high as the above three major properties, relatively safe. Overall performance is not as good as lithium manganese or three yuan alloy.

Therefore, the use of lithium ion batteries in winter is not shorter than summer. By the way, the lithium-ion battery is best not to charge in winter. Due to the low temperature, lithium ions embedded on the negative electrode will exist ion crystallization, straight penetration membrane.

It is usually caused by micro-short, affecting life and performance. Serious, hey! So some people think that the charging of lithium-ion batteries cannot be carried out in winter. Some batteries with a battery management system are due to product protection, and others are due to quality problems.

It is said that the products of ATL (the domestic leader who have just entering Apple) have also experienced such a situatio.
