Effect of Temperature during Open Vessel Sintering on Li6PS5Cl Solid-State Electrolyte Powders for Use in Cathode Composite Electrodes

The sulfide solid electrolyte Li6PS5Cl has beenshown to be an ideal candidate for use in composite electrodes forall solid-state lithium-ion batteries due to its high ionicconductivity, low activation energy, and rapid processability insolvents (solution-based processing). Many reports for solution-...

Many reports for solution-based processing of Li6PS5Cl required the electrolyte to bedensified or sealed inside of a closed-quartz vessel prior to a finalhigh-temperature sintering step.

The lack of information regarding the sintering of Li6PS5Cl powders for bulkprocessing warrants an investigation into open vessel sintering of solely the Li6PS5Cl electrolyte powders, which can later be used incomposite electrodes. This research uses a solution-based processing technique to synthesize Li6PS5Cl prior to sintering in open-topborosilicate glass containers.
