Abstract
Electrolyte for a solid-state battery includes a body having grains of inorganic material sintered to one another, where the grains include lithium. The body is thin, has little porosity by volume, and has high ionic conductivity.
Claims6
Electrolyte for a solid-state battery, comprising:
- a body comprising ceramic grains sintered to one another, wherein the grains comprise lithium,
- wherein thickness of the body, between first and second major surfaces thereof, is in a range from 3 μm to 1 mm;
- wherein the first and second major surfaces of the body have an unpolished granular profile such that the profile includes grains protruding outward from the respective major surface with a height of at least 25 nm and no more than 150 μm relative to recessed portions of the respective major surface at boundaries between the respective grains;
- wherein the body has ionic conductivity greater than 5×10−5 S/cm.
