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 Li2S, P2S5, and P2O5 so as to satisfy a relation of (Li2S)/(P2S5+P2O5)<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.
