Abstract

Spinel LiCr_xMn_2-xO₄ is an appealing candidate cathode material for Li-ion rechargeable batteries, but it suffers from severe capacity fading, especially at higher temperature (55^oC) during discharging/charging. In recent years, many attempts have been made to synthesize modified LiMn₂O₄. This paper reviews the recent research on the structure of LiCr_xMn_2-xO₄, preparation and doping modes of doped chromium for modifying LiMn₂O₄ as LiCr_xMn_2-xO₄ by solid state reaction and microwave synthetic methods. From this paper, we also can see that spinel LiCr_xMn_2-xO₄ as an attractive candidate cathode material for Li-ion batteries can be synthesized by microwave irradiation need optimization.
