Abstract

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 LiNiO 2 to be achieved while using up to 7% less lithium and avoiding tedious postprocessing steps, thus facilitating synthesis and improving battery performance.
