Abstract

Li-Metal Batteries

In article number 2402988, Janghyuk Moon, Hongkyung Lee, and co-workers propose a sustainable surface lithiophilicity for current collectors to extend the cycle life of zero-excess Li-metal batteries (i.e., anode-free batteries). The cover image metaphorically illustrates the different extents of interdiffusion of alloy metals toward Li metal, which affects their preservation over repeated Li plating/stripping cycles. Li-alloyable metals with limited interdiffusion can be well-preserved, sustainably suppressing Li dendrites and enhancing cycling performance.

维持零损耗锂金属电池集流体上超薄锂合金涂层层的表面嗜锂性（第 47/2024 号小论文）

锂金属电池在文章编号 2402988 中，Janghyuk Moon、Hongkyung Lee 及其合作者提出了一种可持续的集流器表面亲锂性，以延长零过量锂金属电池（即无阳极电池）的循环寿命。封面图片隐喻了合金金属向锂金属相互扩散的不同程度，这影响了它们在反复锂电镀/剥离循环中的保存。相互扩散有限的锂合金金属可以很好地保存，持续抑制锂枝晶并提高循环性能。
