The Effect of Sintering Temperature and Carbon Content on the Properties of Li0.84Ni0.08MnPO4/C Synthesized by Sol-Gel Method

Abstrak

Li0.84Ni0.08MnPO4/C composite cathode materials for lithium ion battery are synthesized by sol-gel method followed by heat treatment in the air. Field-emission scanning electron microscopy (FE-SEM) measurements show that firing temperature affects the morphology of the end products. X-ray powder diffraction (XRD) analysis indicates that the samples are olivine-structured. The galvanostatic charge-discharge results show that the optimal firing temperature registers 400°C, and that sample Ni008-20%-400 possessed the best properties with its initial discharge capacity of 145.3 mAhg-1 at 0.02C rate and good capacity retention at a high C-rate.
