Abstract

With rapid development of new energy industry like electric vehicles and energy storage station, these fields highly demand the next generation of high performance Li-ion battery systems with stronger energy density, higher power density, and longer cycling life. Lithium-rich Mn-based cathode materials, xLi₂MnO₃·(1-x)LiMO₂(M=Mn, Co, Ni...), have become the hot topic and drawn attentions of scholars worldwide because of their high reversible capacity exceeding 240 mAh·g^-1, excellent electrochemical properties, and low cost, which makes them most promising cathode material candidates for next Li-ion battery system. The cathode material Li[Li_0.2Mn_0.54Ni_0.13Co_0.13]O₂ prepared in our laboratory shows high initial discharge capacity of 277.3 mAh·g^-1 with retention of 98.4% after 50 cycles. Based on our previous works, we have introduced and reviewed the structures, preparation methods, and charge/discharge mechanisms of these lithium-rich Mn-based cathode materials xLi₂MnO₃·(1-x)LiMO₂.
