Densification of Garnet-type Electrolyte Thin Sheets by Cold Sintering

A garnet-type electrolyte sheet for all-solid-state batteries was fabricated by modified cold sintering method. The pores in the electrolyte sheet were closed during the cold sintering process, and the grain-boundary resistance was reduced. The impurity phase formed after cold sintering was removed...

Beschreibung
Zusammenfassung:	A garnet-type electrolyte sheet for all-solid-state batteries was fabricated by modified cold sintering method. The pores in the electrolyte sheet were closed during the cold sintering process, and the grain-boundary resistance was reduced. The impurity phase formed after cold sintering was removed by annealing treatment at higher temperatures.
