[Xiaomi Auto's new patent can be used to manufacture battery products with higher volume energy density] The Qichacha APP shows that the patent for "lithium iron phosphate material and its preparation method, lithium-ion battery" applied by Xiaomi Automobile Technology Co., Ltd. was recently announced. The Qichacha patent abstract shows that the present invention adopts hydroxy iron phosphate containing metal doping elements and iron phosphate containing metal doping elements as ferrophosphorus sources to improve the electronic conductivity and lithium ion transmission efficiency of lithium iron phosphate materials, and constructs a quaternary gradation system by matching particles of different particle sizes. While improving the compaction density of lithium iron phosphate materials, it ensures that the capacity is effectively utilized. The lithium iron phosphate material can be used to manufacture lithium-ion battery products with higher volume energy density, better rate performance, and longer cycle life. It meets the stringent requirements of high-end application markets such as long-range electric vehicles and high-efficiency energy storage systems, and has high market potential and application value.
