SINTERED ELECTRODES FOR BATTERIES AND METHOD OF PREPARING SAME

Abstract:

A sintered electrode for a battery, the sintered electrode having a first surface positioned to face a current collector and a second surface positioned to face an electrolyte layer, such that the sintered electrode includes: a chalcogenide compound having at least one of an alkali metal or an alkaline earth metal; such that the sintered electrode has a thickness between the first surface and the second surface of 2 .mu.m to 100 .mu.m; and such that the sintered electrode has an open porosity of from 0.1% to 30%. A cathode for a battery, includes: a sintered electrode having a first surface and a second surface; such that the sintered electrode: has a thickness between the first surface and the second surface in a range of 2 .mu.m to 100 .mu.m, has a cross-sectional area of at least 3 cm.sup.2, and is a substrate of the battery.
