【摘要】 正极材料Li_xMn₂O₄是近几年锂离子电池研究的热点,但其在循环过程中的容量衰减是制约锂离子电池商品化的关键。Li_xMn₂O₄的溶解、晶型转变、过充和过放是导致正极材料Li_xMn₂O₄循环过程中容量损失的关键因素,概述了近几年在这方面的研究进展,并提出了当前解决问题的一些途径。更多还原

【Abstract】 The research on lithium ion battery has focused on positive material Li_xMn₂O₄, over the past few years, yet its capacity loss during cycling has greatly restricted the commercialization of Li-ion battery. Among the fac- tors that are responsible for capacity loss of spinel,its dissolution,phase transition,overcharge and overdischarge are the most critical. In this paper, the latest advances are summarized and some solutions are suggested更多还原
