Abstract
A method of manufacturing an all-solid-state battery and an apparatus for manufacturing the same are provided. The method of manufacturing the all-solid-state battery includes: (a) a step of forming a non-woven fabric having a fiber made of a resin; (b) a step of applying a slurry containing solid electrolyte particles onto the non-woven fabric; (c) a step of drying the slurry on the non-woven fabric by a heater; (d) a step of pressurizing the slurry on the non-woven fabric by a roller; (e) a step of forming a positive electrode member on one surface of the solid electrolyte membrane; and (f) a step of forming a negative electrode member on the other surface of the solid electrolyte membrane. The step (a) is a step of forming the non-woven fabric by making a resin containing a polar filler fibrous by a laser electrospinning method. By such a method, the all-solid-state battery (a laminated body of a positive electrode member, a solid electrolyte membrane, and a negative electrode member) can be efficiently manufactured.
