Herein, we deliberately used substoichiometric amounts of lithium hydroxide for preparing layered Ni-rich oxide cathode materials with minor or even no residual lithium being present on the particle surface. This approach allows record capacities with LiNiO₂ to be achieved while using up to 7% less lithium and avoiding tedious postprocessing steps, thus facilitating synthesis and improving battery performance.

通过层状富镍氧化物阴极的亚化学计量合成解决残余锂问题


在此，我们特意使用亚化学计量量的氢氧化锂来制备层状富镍氧化物阴极材料，颗粒表面存在少量甚至没有残留锂。这种方法可以实现 LiNiO₂ 的创纪录容量，同时减少高达 7% 的锂使用量，并避免繁琐的后处理步骤，从而促进合成并提高电池性能。
