摘要：

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.
