Title:
FLEXIBLE SULFIDE SOLID ELECTROLYTE AND ALL SOLID-STATE BATTERIES COMPRISING THE SAME
Document Type and Number:
WIPO Patent Application WO/2024/020300
Kind Code:
A3
Abstract:
This disclosure relates to a flexible membrane of sulfide solid electrolyte. In one embodiment, the flexible membrane has a bending strain of no less than 0.1%. In one embodiment, the flexible membrane has a lithium-ion conductivity of no less than 0.5 mS/cm. The bending strain is calculated according to the formula εM = h/(2r), wherein h is thickness of the membrane and r is a bending radius corresponding to the membrane without any observable kinks, wrinkles, cracks, or damages.
