Document Type and Number:
WIPO Patent Application WO/2022/085176
Kind Code:
A1
Abstract:
A main object of the present disclosure is to provide an all solid state battery including a dispersant-containing layer with good solid electrolyte dispersibility. The present disclosure solves the above problem by providing an all solid state battery comprising a cathode layer, an anode layer, and a solid electrolyte layer disposed between the cathode layer and the anode layer, and at least one of the cathode layer, the anode layer, and the solid electrolyte layer is a dispersant-containing layer including at least a solid electrolyte and a dispersant, an amine value of the dispersant is 20 mgKOH/g or more and 200 mgKOH/g or less, a weight-average molecular weight of the dispersant is less than 1,500,000 g/mol, and a proportion of the dispersant in the dispersant-containing layer is 0.1 weight% or more and 20 weight% or less.
