Important temperature characteristics of single battery

What are the important temperature characteristics of a single battery? If the quality of a single battery is not up to standard, the overall quality of the battery will decrease. Therefore, many people pay great attention to the quality of the single battery when buying batteries. Therefore, in addition to knowing the new quotation of the single cell when purchasing, it is also important to know in advance what important temperature performance of the single cell. What are the important temperature characteristics of a single battery? 1. Low temperature performance is well known, in a low temperature environment, battery capacity and discharge will be bad, because under low temperature conditions, the vitality of lithium batteries and electrode active materials will be a decline The trend, and lowering the temperature, will drop faster, resulting in a slower rate of lithium ion insertion in the anode material. In this case, once the battery is charged at a power exceeding the allowable power of the single battery, it will cause the elementary crystals in the lithium battery Formation, affecting the quality and use of single cells. However, the higher the quality of a single battery, the better its low temperature performance. Although it will be affected, the impact will be relatively small. 2. Compared with low temperature performance, high temperature performance refers to the performance of a single battery in a high temperature environment. Under normal circumstances, at high temperatures, the negative surface film of the battery begins to dissolve, causing the battery cell to enter a self-heating state. If the high-temperature performance of a single battery is good, the battery's membrane, electrolyte, and cathode and anode materials can maintain relatively good stability in a relatively high-temperature environment. Therefore, even working at high temperatures will not cause accelerated degradation of battery life, and will not easily cause thermal runaway accidents. Because the temperature of the environment affects the life and use of the single battery relatively greatly, when buying, in addition to understanding what single battery is of good quality and low price, you know in detail how high the low temperature performance of the single battery processed by the factory is. , Only in the high temperature and low temperature tolerance, the better the single cell use is more stable.
