Abstract
Gelatin is an effective additive of the cathode, which would regulate and control the crystal and morphology of LiFePO4/C composite for enhancing electrochemical performance of the lithium ion battery. The influence of gelatin concentration on the preparation of LiFePO4/C composite has been investigated. It is observed by SEM that the shape transformed from sphere-like to rod-like structure with the gelatin concentration increased from 1Â wt.% to 5Â wt.%; meanwhile, the lattice parameters first showed increase trend and then decrease. The LiFePO4/C composite obtained with the 2Â wt.% gelatin solution shows the lowest polarization and excellent rate performance.
