Will temperature harm the ternary lithium battery?

Ternary materials have a higher safety factor for positive rechargeable batteries, but the working voltage is too low, and when used on mobile phones (the cut-off voltage on mobile phones is generally up and down), there will be a significant sense of insufficient volume. The ternary lithium battery has universal operating temperature adaptability, and the maximum value of electric heating reaches 350℃-500℃. Compared with the general lead-acid battery, its energy storage capacity is stronger, and its raw materials are also lighter. Because the ternary lithium battery is a kind of rechargeable battery lithium battery, its output voltage is stable, the output voltage is high, the characteristics are stable, the volume is large, the service life is long, the operating temperature range is wide, the safety factor is good, and the natural environment is zero pollution, so it is in the development direction There is a very large improvement of the indoor space on the road surface, but it is still necessary to continue to explore in order to achieve the goal of improving its own shortcomings. Will temperature harm the ternary lithium battery? For the detailed use of lithium batteries, the high-temperature reliability of raw materials must be considered. Under normal circumstances, rising temperature can improve the dynamic model standard of ternary lithium batteries, thereby improving the characteristics of rechargeable batteries. It seems obvious that the capacity is sufficient, but the high temperature has certain hazards to the reliability of the circulation system of the raw materials. For example, at a normal temperature of 20°C, when the three raw materials of a ternary lithium battery are cycled in the first 50 cycles, the cycle system characteristics are close, but when the temperature rises to 60°C, the NMC811 and NCA raw material cycle systems can perform 50 cycles. The volume maintenance capacity is clearly smaller than that of the NMC622 raw material, declaring that the NMC622 raw material has good heat resistance. In essence, with the increase in the frequency of de-lithiation of NMC raw materials, the battery charge cut-off voltage, air oxidation working voltage, current flow, and operating temperature of the ternary lithium battery will harm the characteristics of the NMC and NCA raw material circulation system, which will cause NMC raw materials. The reliability of the structure is reduced, thereby jeopardizing its circulatory system characteristics. In addition, high temperature will continue to cause unfavorable harm to the reliability of raw materials, which in turn will reduce the characteristics of the circulation system. Regarding the characteristics of the NMC raw materials, a new upgraded battery charging system software was designed, that is, not only the cut-off volume is limited, but also the battery charging working voltage is adjusted to ensure that the rechargeable battery has the same charging volume every time, thereby eliminating the need for rechargeable batteries. The attenuation coefficient of the battery charge volume caused by the over-potential difference further improves the cyclic system characteristics of the ternary lithium battery.
