| Abstract: | The diamond like and Ag embedded LiFePO_4/C was synthesized by hydrothermal method with Li_2CO_3 as lithium source. The sample was studied by XRD, SEM, galvanostatic charge-discharge test, cyclic voltammetry and AC impedance methods. The sample had perfect crystalline and uniform particle size; the capacity had no fading when cycled 600 times at 1 C,the specific capacity was 130.2 mAh/g at the 600th cycle; when cycled 800 times at 15 C,the capacity retention was 96.4%. |
