A LiAlO2 and LiFePO4 shell boosts lithium-ion transport in cobalt-free single-crystal cathodes, improving capacity, rate, and cycling.
Low-temperature sodium hydroxide precipitation recovers commingled cathode metals for new lithium-ion materials with less energy use.
Defect-doped oxyhalide precursors replace sulfide and hard oxide electrolytes to boost ionic conductivity while avoiding H2S release and poor formability.
Complex 3D abrasive grains use asymmetric geometry and upright orientation to improve stock removal and surface finish while avoiding binder sticking.
