鋰離子電池富鋰錳基正極材料的研究進展
[Abstract]:With the rapid development of new energy sources such as electric vehicles and energy storage power stations, the energy density, power density and cycle life of the next generation of high-performance lithium ion batteries have been put forward higher requirements. Lithium-rich manganese based cathode material x Li2Mn O3 _ (1-x) Li MO2 (0x1H _ 2O _ 2) It has the advantages of high reversible specific capacity (240 ~ 280m Ah g ~ (-1) 2. 8 V), electrochemical performance and low cost. It has attracted the attention of researchers and is expected to be a cathode material for the next generation of lithium ion batteries. In our laboratory, different lithium-rich manganese based cathode materials were prepared by solid phase method and sol-gel method. The specific discharge capacity of Li [Li0.2Mn0.54Ni0.13Co0.13] O _ 2 electrode prepared by sol-gel method was 277.3 m Ah g ~ (-1) 50 cycles, and the capacity of the electrode was 272.8 m Ah g ~ (-1) after 50 cycles, and the capacity retention was 98.4%. In this paper, the structure, synthesis, electrochemical performance modification and charge-discharge mechanism of x Li2Mn O3 (1-x) Li MO2, a new lithium-rich manganese-rich cathode material, are summarized and reviewed.
