Laser Sintering of Solid Electrolyte for the Next Generation Battery

Inorganic solid electrolytes enable the next generation battery with enhanced safety, increased volumetric energy density and expanded operating temperature range in comparison to their liquid counterparts. However, after the reagent’s synthesis a densification process, the sintering, follows which describes a heat treatment with high temperatures and enduring dwell times. In general, sintering densifies the samples […]
