How safe is a lithium iron phosphate batterie?
Lithium iron phosphate (LiFePO₄) battery’s thermal stability is significantly greater than that of other lithium-ion batteries. Its thermal runaway onset temperature reaches as high as 800-1000°C (200-300°C for ternary lithium battery), and the surface temperature only reaches 150°C in the needle-puncture test (GB/T 31485 standard). And there is no open flame and explosion involved (CATL …
