Abstract
A solid electrolyte, particularly a lithium-conductive solid electrolyte, can be obtained from a glass-ceramics process. A glass-ceramics process can be used to produce a solid electrolyte, particularly a lithium-conductive solid electrolyte. The solid electrolyte can be LAGP, i.e. Li1+xAlxGe2—x(PO4)3 modified by a crystallization nucleation agent.
Claims15
A solid electrolyte, obtained in a glass-ceramics process, wherein the solid electrolyte is LAGP (Li1+xAlxGe2-x(PO4)3) modified by a crystal nucleation agent.
A method of synthesizing LAGP (Li1+xAlxGe2-x(PO4)3) in a glass-ceramics process, comprising:
- a) providing a crystallization agent which is configured to crystallize in a glass-ceramics process prior to a main lithium-conductive phase,
- b) adding said crystallization agent and a crystallization nucleation agent to a glass melt at a temperature that is between 1000° C. and 1500° C.,
- c) obtaining uniform glass plates via quenching, and
- d) annealing said glass plates in a two-stage program including crystallization of the crystal nucleation agent prior to crystallization of the main lithium-conductive phase.
A method of using LAGP (Li1+xAlxGe2—x(PO4)3) modified by a crystallization nucleation agent in a lithium/air-battery system for a Hybrid Electric Vehicle (HEV), a Plug-in Hybrid Electric Vehicle (PHEV) or an Electric Vehicle (EV).
