With the implementation of carbon peaking and carbon neutrality policies, the importance of new energy vehicles has gradually become prominent. As the core driving component of new energy vehicles, power batteries account for 30% -50% of the total vehicle cost, indicating their importance. So when choosing new energy vehicles, understanding their batteries is an essential lesson. Below is a scientific introduction to the characteristics of lithium iron phosphate batteries.

　　Lithium iron phosphate battery is a lithium-ion battery that uses lithium iron phosphate (LiFepo4) as the positive electrode material and carbon as the negative electrode material. Compared with the positive electrode material of traditional aluminum ion secondary batteries, lithium iron phosphate has a wider source of raw materials, a relatively low price, and does not cause environmental pollution. The characteristic of lithium iron phosphate battery is also its advantage, which is its reliable safety. Given the relatively stable chemical characteristics of the positive electrode material of lithium iron phosphate batteries, it has a relatively stable charging and discharging platform, and the battery structure will not change during the charging process, without combustion or explosion. Even if there is a short circuit, compression, or puncture, there is still sufficient safety.

　　Lithium iron phosphate batteries have a longer lifespan, with a cycle life of up to 2000 cycles or even over 3500 cycles. High temperature performance is also good, able to withstand high temperatures of 350 ℃ -500 ℃, while other batteries are only around 200 ℃. In addition, lithium iron phosphate can achieve 3C to C rate charging, greatly saving time and cost.
