Study on the Synthesis CMCAB Electro Spinning Carbon-Coated LiFePO₄ Anode Materials

Abstract:

LiFePO₄ was spinning with cellulose derivatives by electrostatic spinning for the first time. Processing conditions were adjusted to the solution concentration of 15%, an applied voltage of 25KV, the quality of mixed solvent with 4:1, and then about 0.1μm nano-fibrous non-woven fabrics can be obtained. FTIR showed that the CMCAB was synthesized successfully. Coulomb efficiency of electrode materials before and after the modification was maintained at about 100%, specific capacity of the battery in 2C of discharge rate, it was the first time that discharge specific capacity had increased from the unmodified 147.6 mAh.g^-1 to the modified 160.6 mAh.g-1^{Superscript text}. After 200 weeks' cycle, the capacity loss decreased from 11.38% to 5.11%.
