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.
Un objet principal de la présente invention est de fournir une batterie entièrement solide comprenant une couche contenant un dispersant ayant une bonne dispersibilité d'électrolyte solide. La présente invention résout le problème ci-dessus en fournissant une batterie entièrement solide comprenant une couche de cathode, une couche d'anode, et une couche d'électrolyte solide disposée entre la couche de cathode et la couche d'anode, et au moins l'une de la couche de cathode, la couche d'anode, et la couche d'électrolyte solide étant une couche contenant un dispersant comprenant au moins un électrolyte solide et un dispersant, une valeur d'amine du dispersant est de 20 mgKOH/g ou plus et de 200 mgKOH/g ou moins, un poids moléculaire moyen en poids du dispersant est inférieur à 1500000 g/mol, et une proportion du dispersant dans la couche contenant un dispersant est de 0,1 % en poids ou plus et de 20 % en poids ou moins. |
