Abstract

Lithium phosphate is a commonly used material for lithium battery-positive electrode materials, with high energy density, high stability, and long service life. Still, it also has disadvantages such as poor conductivity and heavy weight. Discussion based on the structure and electrochemical properties of lithium iron phosphate, this review focuses on the modification methods of carbon-coated, nitrogen doping, and nitrogen-sulfur co-doping. It analyzes the electrochemical properties after doping through impedance tests, EIS, SEM, and other methods. It can be found that these methods can effectively reduce the charge transfer resistance and increase initial discharge capacity, making the battery have a higher and more stable capacity. This review also discusses the synthesis method of doped lithium iron phosphate. Two methods are introduced: using sucrose and melamine as carbon sources and using polydopamine as a precursor. Also shows the synthetic advantages and improvement principles. Both methods can indicate good electrochemical performance of lithium iron phosphate doped with nitrogen.
