| Abstract: | Electrochemical performances of Mn-series power batteries produced by MGL were studied, and compared with LiFePO4 power batteries of other companies. The results indicate that the high capacity and high power batteries with spinel LiMn2O4 and multi metal oxides as cathode materials not only have high voltage, high energy density, good high and low temperature properties, excellent rate of charge and discharge, stable thermal performance, but also show the linear of state of charge-open-circuit voltage (SOC-OCV) relationship, and then the battery manage system (BMS) can be easily controlled. Therefore, Mn-series power batteries will be the important direction for future power batteries. |
