Kinetically controlled synthesis of low-strain disordered micro–nano high voltage spinel cathodes with exposed {111} facets

A micro–nano spherical spinel LiNi 0.5 Mn 1.5 O 4 cathode material with highly exposed {111} facets has been designed. This unique structure could inhibit manganese dissolution, facilitate Li + diffusion, and mitigate volumetric strain during cycling.
