The difference in safety between lithium iron phosphate batteries and ternary lithium batteries depends on high temperature resistance, so it is easy to say who can withstand the high temperature and whose reliability is higher.

　　In the case of lithium iron phosphate batteries, the po bond in the crystal must be 700-800c to dissolve. Even in the case of severe impact, pinning and short-circuit failure, it will not release oxygen atoms, and it is not easy to cause strong ignition .

　　Compared with ternary lithium-ion batteries, it can dissolve at 250-300°C, and the electrolyte and carbon materials of the lithium-ion battery electrolyte in the rechargeable battery are dissolved.

　　Due to the heat resistance and organic chemistry reliability of rechargeable batteries, most early pure electric vehicles used lithium phosphate rechargeable batteries. The high-tech lithium ion battery research (ggii) survey data showed that in 2016 and 2017, lithium phosphate batteries were charged. Batteries dominate the market for passenger cars with new energy technologies.

　　However, since 2017, the market share of lithium-ion batteries has just begun to catch up with lithium phosphate rechargeable batteries, and has always been the core of the power lithium-ion battery sales market.
