Abstract: Spinel LiMn 2 O 4 is an appealing candidate cathode material for Li-ion rechargeable batteries, but it suffers from severe capacity fading, especially at higher temperature (55 °C) during discharging/charging. In recent years, many attempts have been made to synthesize modified LiMn 2 O 4 . This paper reviews the recent research on the preparation and doping modes of doped LiMn 2 O 4 for modifying the LiMn 2 O 4 . We firstly compared preparation methods for doped spinel LiMn 2 O 4 , such as solid state reactions and solution synthetic methods. Then we mainly discuss doping modes reported in recent years, such as bulk doping, surface doping and combined doping. A comparison of different doping modes is also provided. The research shows that the multiple-ion doping and combined doping modes of LiMn 2 O 4 used in Li-ion battery are excellent for improving different aspects of the electrochemical performance which holds great promise in the future. From this paper, we also can see that spinel LiMnO 4 as an attractive candidate cathode material for Li-ion batteries.
