Construction of Cu2+-doped MnCO3 micro-rhombohedrons and micro-olives as promising anode materials for high performance lithium-ion batteries

Abstract

As the anode material for lithium-ion battery, Cu2+-doped MnCO3 micro-olives are prepared by a solvothermal method, deliver a high capacity and good cycle stability. A reversible capacity of 823.5 mA h g−1 after 1000 cycles at 0.5 A g−1 is achieved.
