A valve regulated lead acid (VRLA) battery is also known as sealed lead–acid (SLA) battery is a type of lead-acid battery. In this type of battery, the electrolyte that does not flood the battery but it''s rather absorbed in a plate separator or silicon is added to form a gel. This causes proportioning of the negative and positive plates such that oxygen recombination is

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 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) .
