| 摘 要： | 以LiNi0.8Co0.1Mn0.1O2（NCM811）为正极、中间相碳微球（MCMB）为负极构建锂离子全电池，研究了充放电电压区间对NCM811/MCMB全电池电化学性能的影响。研究结果表明：以4.3 V为充电截止电压，降低放电截止电压可提高全电池的容量，但高放电截止电压下全电池的循环性能更加稳定；在2.8~4.3 V电压区间下，NCM811/MCMB全电池不但具有高的比容量，同时还具有良好的循环性能和充放电可逆性。

| Abstract: | NCM811/MCMB lithium ion batteries have been constructed using LiNi0.8Co0.1Mn0.1O2 (NCM811) and mesocarbon microbeads (MCMB) as cathode and anode, respectively. The effects of varying the voltage range on the electrochemical performance of NCM811/MCMB cells were investigated. The results indicate lower discharge cut-off voltages can increase the capacity of the full cell when fixing the cut-off voltage of charging at 4.3 V, while higher cut-off discharge voltages can improve the cycle durability of the cells. In the voltage range 2.8-4.3 V, the NCM811/MCMB full cell not only has high capacity, but also good cycling performance and charge-discharge reversibility. |
