摘要

Layered LiMn_(0.5)Ni_(0.3)Co_(0.2)O_2 was prepared from Mn(NO_3)_2, Ni(NO_3)_2, Co(NO_3)_2 and LiOH by co-precipitation and solid state reaction. XRD, C-V and galvanostatic charge-discharge methods were used to examine the structural and electrochemical characteristics. The LiMn_(0.5)Ni_(0.3)Co_(0.2)O_2 delivered a high discharge capacity of 167 mAh/g between 2.5 and 4.3 V with excellent cycling stability.
