Invited for this month's cover is the group of Tobias Placke and Martin Winter at the MEET Battery Research Center (University of Münster). The image shows the failure mechanism of high-voltage operated NCM523 || graphite lithium-ion cells, that is, the dissolution of transition metals (Mn, Co, Ni) from the NCM523 cathode and subsequent deposition at the graphite anode, resulting in formation of Li metal dendrites. The Full Paper itself is available at 10.1002/cssc.202002113.
本月的封面文章由明斯特大学MEET电池研究中心的托比亚斯·普拉克（Tobias Placke）和马丁·温特（Martin Winter）团队撰写。图中展示了高压运行的NCM523||石墨锂离子电池的失效机制，即过渡金属（锰、钴、镍）从NCM523阴极溶解，随后沉积在石墨阳极上，导致锂金属枝晶的形成。完整论文可在10.1002/cssc.202002113获取。
