Abstract

Lithium iron phosphate is currently one of the main anode materials for electric vehicles in China. It is widely produced and used because of its excellent stability, higher service life and relatively low material costs. However, its relatively lower energy density and charge/discharge efficiency are also major limiting factors for its development. This paper analyzes the current production process including solid-state process and solution-based process. Both methods have received process improvements from vendor’s patents, where carbon coating and decreasing particle size are proved more effective and commonly used in China.
