The effect of Lithium source on the electrochemical performance of UFePO_4/C cathode materials synthesized by Sol-gel method

摘要

LiFePCVC cathode materials were synthesized by Sol-gel method under the same process conditions using different water-soluble lithium source (LiOH, Li_2CO_3, LiNO_3). The phase of vynthesized powders were characterized by XRD;;and the electrochemical performance of the material was investigated by measurements of cyclic voltammetry, AC impedance measurements, charge and discharge.
