球磨对磷酸铁锂正极材料性能的影响

Abstract

Abstract: LiFePO₄ cathode material for lithium-ion batteries was synthesized by high temperature solid-state reaction with either wet ball-milling or dry ball-milling procedure.Effect of different ball-milling time on performance of the samples was discussed.Morphology of the cathode material and electrochemical performance were characterized by SEM and the electrochemical performance testing.Results indicated that the samples obtained from wet balling-milling for 10 h displayed the best discharge capacity.Its first specific discharge capacity was 114 mA·h/g at 0.1 C.

Key words: cathode material, balling-milling, lithium iron phosphate

CLC Number:

TQ126.35
