Abstract
The present disclosure relates to a nano-engineered coating for cathode active materials, anode active materials, and solid state electrolyte materials for reducing corrosion and enhancing cycle life of a battery, and processes for applying the disclosed coating. Also disclosed is a solid state battery including a solid electrolyte layer having a solid electrolyte particle coated by a protective coating with a thickness of 100 nm or less. The protective coating is obtained by atomic layer deposition (ALD) or molecular layer deposition (MLD). Further disclosed is a solid electrolyte layer for a solid state battery, including a porous scaffold coated by a first, solid electrolyte coating. The solid electrolyte coating has a thickness of 60 μm or less and a weight loading of at least 20 wt. % (or preferable at least 40 wt. % or at least 50 wt. %). Further disclosed is a cathode composite layer for a solid state battery.
