Effect of Carbon-Coating on Internal Resistance and Performance of Lithium Iron Phosphate Batteries

“…[3][4][5][6][7] However, due to the one-dimensional diffusion mechanism of Li + in the LiFePO 4 cathode material and the hindrance of its tetrahedron, the Li + diffusion coefficient and electronic conductivity are low, which restricts the performance of LiFePO 4 and limits its application. [8][9][10][11] Therefore, in order to effectively overcome these defects and improve the performance of LiFePO 4 materials, the modification methods including carbon coating, [12][13][14][15][16][17] element doping, [18][19][20][21][22][23][24] nanometerization, [25][26][27][28][29] and excimer laser modification [30][31][32] of LiFePO 4 cathode materials were studied. In the modification research of LiFePO 4 cathode material, carbon coating is not only beneficial to improve the conductivity of the cathode material, control the grain size, but also facilitate the migration of lithium ions, thus it has a great influence on reducing the internal resistance of LiFePO 4 batteries.…”
