Manufacturing method of solid-state electrolyte layers for rechargeable solid-state batteries

The present disclosure relates to a manufacturing method of pore-free dense solid-state electrolyte layers for rechargeable solid-state batteries. Using conventional casting methods used in the field of rechargeable batteries, solid-electrolyte-precursor materials are coated on electrodes. In order to manufacture the dense solid-state electrolyte layers, an electron beam is employed to electro-magnetically scan the coated precursor materials with a high speed. The intense electron beam rapidly increases temperatures of the materials with a fast-scanning rate and makes uniform melting of the precursor materials. In this way, the dense solid-state electrolyte layers are manufactured while minimizing thermal damages of electrodes.
