Li2MnO3-stabilized LiMO2 (M = Mn, Ni, Co) electrodes for lithium-ion batteries

Abstract

A strategy used to design high capacity (>200 mAh g⁻¹), Li₂MnO₃-stabilized LiMO₂ (M = Mn, Ni, Co) electrodes for lithium-ion batteries is discussed. The advantages of the Li₂MnO₃ component and its influence on the structural stability and electrochemical properties of these layered xLi₂MnO₃·(1 − x)LiMO₂ electrodes are highlighted. Structural, chemical, electrochemical and thermal properties of xLi₂MnO₃·(1 − x)LiMO₂ electrodes are considered in the context of other commercially exploited electrode systems, such as LiCoO₂, LiNi_0.8Co_0.15Al_0.05O₂, Li_1+xMn_2−xO₄ and LiFePO₄.
