The safety of energy storage systems relies heavily on thermal runaway early warning protection and cooling intervention fire extinguishing agents for large-capacity lithium iron phosphate batteries (LiFePO4). An integrated platform was established to trigger fires through heating abuse coordinate with at the cell/module level. Key indicators battery evolution process were constructed, identifying 16 multidimensional signal characteristics representing failure, hydrogen gas production rate contribution ratio being highlighted as critical signals. Based maximum voltage drop duration soft short circuits, effects perfluorohexanone-based explored reduce risk index explosion lowest Through concentration tests under various conditions, a three-level mechanism established, setting thresholds hydrogen, volatile organic compound, carbon dioxide, smoke, temperature. establishment mechanisms is crucial improving strategies against runaway.
