摘要

锂离子电池（LIBs）中的层状富镍氧化物阴极通常都存在热安全性差和容量衰减的问题。Xin 及其同事在《自然》和《自然-能源》杂志上的研究展示了一种新型高熵（成分复杂）掺杂策略，引入了多种成分的 "鸡尾酒效应"。这种方法大大提高了循环性能和稳定性，降低了材料成本，并可能为开发下一代 LIB 的先进电极铺平道路。

Stabilizing Layered Cathodes by High-Entropy Doping.

Layered Ni-rich oxide cathodes in lithium-ion batteries (LIBs) often struggle with poor thermal safety and capacity fade. Xin and colleagues' studies in Nature and Nature Energy demonstrate a novel high-entropy (compositionally complex) doping strategy, introducing "cocktail effects" from multiple constituents. This approach substantially improves cycling performance and stability, reduces material cost, and may pave the way toward the development of advanced electrodes for next-generation LIBs.
