High-Performing LiMg_<i>x</i>Cu_<i>y</i>Co_{1–<i>x</i>–<i>y</i>}O₂ Cathode Material for Lithium Rechargeable Batteries

Abstract

Sustainable power requirements of multifarious portable electronic applications demand the development of high energy and high power density cathode materials for lithium ion batteries. This paper reports a method for rapid synthesis of a cobalt based layered cathode material doped with mixed dopants Cu and Mg. The cathode material exhibits ordered layered structure and delivers discharge capacity of ∼200 mA h g(-1) at 0.2C rate with high capacity retention of 88% over the investigated 100 cycles.
