Introduction Overcharge is one of the difficult to pass in the current lithium battery safety test, so it is necessary to understand the overcharge mechanism and the current measures to prevent overcharge. Figure 1 shows the voltage and temperature curve of the NCM+LMO/Gr system battery when it is overcharged. The maximum voltage is reached at […]
