Review on thermal safety of energy storage lithium batteries
The safety of lithium ion battery energy storage power stations is an important factor re-stricting energy reform and the realization of the long-term goal of"dual carbon".Once a safety acci-dent occurs in the energy storage power station,the property losses and casualties will be very seri-ous.In view of the thermal safety problem of lithium energy storage battery,this paper comprehen-sively summarizes the causes of lithium battery thermal runaway,and analyzes the characteristic pa-rameters of lithium battery thermal runaway on this basis.By monitoring the temperature,internal resistance,voltage and characteristic gas of the lithium battery,it can provide the basis for the early warning of the lithium battery thermal runaway.However,the monitoring of these parameters de-pends on the accuracy and sensitivity of the sensor elements,and higher precision and more reliable sensors are needed.The safety of lithium batteries is fundamentally improved by improving the safety of positive and negative materials of lithium batteries,using additives,non-flammable electro-lyte solvents,developing innovative electrolysis systems,and improving the thermal stability and safety of the diaphragm.
