Improvement of LiFePO4 electrochemical performance by organic zinc source doping in combination with crystalline carbon layer capping

In this paper, [Formula: see text] cathode materials are prepared by hydrothermal method and co-modified using the synergistic effect of doping and capping. We investigate the effects of [Formula: see text] doping and DPHP capping layer on the crystalline, microstructure, and electrochemical properties of LFP cathode materials, and the results indicate that the discharge capacity of the co-modified cathode material with 5% [Formula: see text] doped and 7% DPHP capping layer is 162.1 mAh ⋅ [Formula: see text], and the rate of capacity retention is still as high as 98.5% after 200 times of discharging and charging.
