Abstract
An inorganic solid-state electrolyte and a battery prepared by electron beam heating and a method, in the method, the inorganic solid-state electrolyte powder is pressed into a green body after drying and homogenization treatment; the graphite is used as a heat carrier to coat the green body and fix the green body on a metal substrate, and then the green body is placed in an electron beam heat processing area; the coordinate information of the electron beam heat processing area, the processing time and the heat source processing parameters are set, the surface of the heat carrier is irradiated by scanning under the electron beam to generate heat, and the heat field uniformly distributed in the heat carrier causes the green body in the heat carrier to realize sintering.
