“…However, the low electric conductivity and low diffusion coefficient of Li + are the main shortcomings that limit its application in industry. Extensive efforts have been performed to improve its electrochemical performance over decades, which can be classified into the following categories: particle size/shape optimizing [1][2][3][4][5][6], metal doping [7], and mixing with the electronically conductive materials like carbon, metal, and metal oxide [8][9][10]. Among these methods used for improving electrochemical properties of LiFePO 4 , carbon coating is one of the most frequently used techniques to improve the specific capacity, rate performance, and cycling life [11,12].…”
