Methods of making a sintered electrode comprise forming a slurry including 40 wt % to 75 wt % of a powder comprising a chalcogenide and at least one of an alkali metal or an alkaline earth metal, 1 wt % to 10 wt % of a binder, and 30 wt % to 50 wt % of a solvent. Methods include casting the slurry into a green tape. Methods include drying the green tape to form a dried green tape by removing at least a portion of the solvent. The dried green tape includes at most 10 wt % of organic material in the dried green tape. Methods include sintering the dried green tape at a temperature from 500&#xb0; C. to 1350&#xb0; C. for no more than 60 minutes to form the sintered electrode.

Sintered electrodes for batteries and method of preparing same

An energy device has an electrode including lithium cobaltite (LCO) grains, where the LCO grains are sintered to one another forming a self-supporting sheet with porous passages. The porous passages wind and branch through the sheet. The energy device further includes a solid electrolyte comprising lithium phosphosulfide (LPS) overlaying a major surface of the sheet and extending into the porous passages. The sheet serves as mechanical support for the solid electrolyte, allowing for high temperature joining of the LPS to the LCO without binder in the LPS.
