Recovered LiCoO2 as anode materials for Ni/Co power batteries

LiCoO2 material is recovered from spent lithium-ion batteries and investigated as anode materials for Ni/Co power batteries for the first time. LiCoO2 electrodes with a small amount of S-doping display excellent electrochemical properties. The electrochemical reactions occurring on M0 electrodes during the first several cycles and after being activated are proposed, respectively. A function mechanism of S powder on M10 electrode is also proposed.
