Abstract
Transition metal oxide is one of the very potential electronic functional materials for lithium ion batteries, because of the low cost and high theoretical capacity. However, the low electron conductivity and poor cycle stability have limited its widely application. In this study, Co3-xMnxO4@C anode material with a uniform porous structure was successfully synthesized by a simple liquid precipitation method that was followed by thermal annealing. Dual strategy modification treatments were performed to obtain materials with the excellent electrochemical performance similar to those of the anode electrodes of lithium batteries. Manganese doping improved the stability, carbon coating enhanced the electrical conductivity, and the combination of the two tactics effectively improved the performance of the Co3O4 anodematerial.
