Abstract
The disclosure relates to ceramic lithium ion electrolyte membranes and processes for forming them. The ceramic lithium electrolyte membrane may comprise at least one ablative edge. Exemplary processes for forming the ceramic lithium ion electrolyte membranes comprise fabricating a lithium ion electrolyte sheet and cutting at least one edge of the fabricated electrolyte sheet with an ablative laser.
Claims21
A ceramic lithium-ion electrolyte membrane comprising
- at least one ablative edge, wherein the at least one ablative edge is an outer edge;

- a relative density greater than about 90%;
- and
- a thickness of up to about 200 μm;
- and
- wherein the membrane has a 2-point strength greater than about 50MPa.
