International Classification:

H01M 4/62
H01M 4/04
H01M 10/0562

Abstract:

An interfacial protective coating layer of LTO is effective in preventing unwanted interfacial reactions between the solid-state electrolyte and cathode electrodes from occurring. Incorporation of the inventive coating into sodium-based all-solid-state batteries allows for room temperature operation, high voltage, and long cycle life.

Assignee:

GM GLOBAL TECHNOLOGY OPERATIONS LLC - Detroit MI

International Classification:

H01M 10/0562
C03C 3/32
C03C 10/00
C03C 4/18
C03B 25/02

Abstract:

A solid state electrolyte including an oxy-sulfide glass or glass ceramic, solid state electrolyte layer having a thickness in the range of ten micrometers to two hundred micrometers is provide. The composition of the electrolyte layer is the reaction product of a mixture initially including either a glass former including sulfur or a glass co-former including sulfur, and a glass modifier including LiO or NaO. The solid-state electrolyte layer is further characterized as having a wholly amorphous microstructure or as having small recrystallized regions separated from each other in an amorphous matrix, the recrystallized regions having a size of up to five micrometers. The solid-state electrolyte layer includes mobile lithium ions or mobile sodium ions associated with sulfur anions chemically anchored in the microstructure.

Inventors:

- DETROIT MI, US
James R. Salvador - Royal Oak MI, US
Han Nguyen - San Diego CA, US

International Classification:

H01M 10/0562
C03C 3/32
C03C 10/00
C03C 4/18

Abstract:

Thin amorphous or partially crystalline lithium-containing and conducting sulfide or oxysulfide glass electrode/separator members are prepared from a layer of molten glass or of glass powder. The resulting glass films are formed to lie face-to face against a lithium metal anode or a sodium metal anode and a cathode and to provide for good transport of lithium ions between the electrodes during repeated cycling of the cell and to prevent shorting of the cell by dendrites growing from the lithium metal or sodium metal anode.
