Abstract
The main object of the present invention is to provide a method for producing an all solid lithium battery, capable of easily performing dew point control in a battery assembly step. The present invention solves the above-mentioned problems by providing a method for producing an all solid lithium battery, comprising the steps of: preparing a material composition by adding LiS, PS, and POso as to satisfy a relation of (LiS)/(PS+PO)<3 on a molar basis, synthesizing a sulfide solid electrolyte from the above-mentioned material composition by a vitrification means, and assembling an all solid lithium battery in an atmosphere having a dew-point temperature of −60° C. or more while using the above-mentioned sulfide solid electrolyte.
