摘要
综述了锂离子电池负极材料研究进展,着重介绍了负极材料活性成分、材料尺度及操作温度对电池比容量、比功率、循环寿命、充放电倍率性能的影响,以及数模化半电池或全电池系统对负极材料电极性能的理论研究。为了提高锂离子电池动力性能,改进碳/石墨和非碳/石墨负极材料、制备高度有序的阵列负极将成为今后研究的重要方向;建立数学模型模拟充放电过程、分析负极材料的电极动力学特性,是表征、优化负极材料的有效方法。
The progress in research of anode materials of lithium-ion batteries is reviewed. The effects of the compositions, the sizes of the anode materials and the operation temperatures on its performance such as specific ca- pacity, specific power, cycle life and charge/discharge rate capability of the battery, are highlighted, as well as the theoretical studies on the anode materials by mathematical modeling the system of full cell or a half cell of the battery. Improving the performance of the anode materials of carbon/graphite and non-carbon/graphite, preparing the high or- derly array anode to enhance the dynamical performance of lithium-ion batteries, will be important aspects for further studying; developing mathematical models to simulate the process of charging and discharging for analyzing the anode dynamics is an efficient way to characterize and optimize the anode materials.
