As the most fundamental energy storage unit of the battery storage system, the battery safety performance is an essential condition for guaranteeing the reliable operation of the energy storage power plant. LIBs are usually composed of four basic materials: cathode, anode, diaphragm and electrolyte .
The safe operation of the energy storage power station is not only affected by the energy storage battery itself and the external operating environment, but also the safety and reliability of its internal components directly affect the safety of the energy storage battery.
The increase in the proportion of Ni and decrease in the proportion of Co in the NCM will improve the capacity of the LIB and reduce the cost, but at the expense of reducing the thermal stability, which means that the battery safety risk will increase (as shown in Fig. 2 b) .
In this paper, the safety limits were selected by empirical methods. While this approach was used, the authors acknowledge that more statistical data could be utilized when defining the probability functions of abuse, given the extensive battery safety tests conducted worldwide.
Lu et al. discuss the safe operating area of a battery, which is based on voltage and temperature. They explain that breaching these limits can lead to various effects, such as the collapse of the positive active material and the dissolution of the copper negative current collector in case of low voltage.
By considering the causes of battery aging in various aspects, such as temperature, charging and discharging parameters, and the number of charges and discharges, the battery health status information is modeled and analyzed for the purpose of predicting SOH .
