Within a suitable temperature range, the higher the temperature, the higher the battery capacity of the lithium battery. Above 0°C, the capacitor is less sensitive to temperature. If the temperature is below 0°C, the capacitance is lower and decreases as the temperature decreases.
Different Li-ion batteries have different operating temperature ranges. That is to say, there is a certain difference between high temperature performance and low temperature performance.
Too high or too low temperature will affect the performance of the lithium battery and shorten the battery life. For example, in the operating temperature range, the high temperature performance of lithium iron phosphate battery is better than that of ternary lithium battery.
