NOVEL LITHIUM METAL SULFIDES AS LITHIUM SUPER-IONIC CONDUCTORS, SOLID ELECTROLYTE AND COATING LAYER FOR LITHIUM METAL BATTERY AND LITHIUM-ION BATTERY

摘要

Solid-state lithium ion electrolytes of lithium metal sulfide based composites are provided which contain an anionic framework capable of conducting lithium ions. Composites of specific formulae are provided and methods to alter the composite materials with inclusion of aliovalent ions shown. Lithium batteries containing the composite lithium ion electrolytes are also provided. Electrodes containing the lithium metal sulfide based materials and batteries with such electrodes are also provided.
