Abstract
Official abstract text for this publication.
The main object of the present invention is to provide an all solid state battery with capability of inhibiting heat generation of an anode layer. The present invention solves the problem by providing an all solid state battery comprising a cathode layer, an anode layer, and a solid electrolyte layer formed between the cathode layer and the anode layer, wherein at least one of the anode layer and the solid electrolyte layer contains a sulfide solid electrolyte material; the anode layer contains an anode active material that is graphite, and contains an additive; and the additive has an oxide that is at least one kind of MoO 3 , Sb 2 O 3 , and MnCO 3 , and a coating portion that coats at least a part of the oxide and includes a resin with a hydrocarbon chain as a main chain.
First claim
Opening claim text (preview).
What is claimed is: 1. An all solid state battery comprising a cathode layer, an anode layer, and a solid electrolyte layer formed between the cathode layer and the anode layer, wherein at least one of the anode layer and the solid electrolyte layer contains a sulfide solid electrolyte material, the anode layer contains an anode active material that is graphite, and contains an additive, and the additive has an oxide that is at least one kind of MoO 3 , Sb 2 O 3 , and MnCO 3 , and a coating portion that coats at least a part of the oxide and includes a resin with a hydrocarbon chain as a main chain. 2. The all solid state battery according to claim 1 , wherein a content of the additive in the anode layer is within a range of 5% by weight to 30% by weight. 3. The all solid state battery according to claim 1 , wherein the resin with a hydrocarbon chain as a main chain is a resin that is softened or decomposed in a range of 100° C. to 200° C. 4. The all solid state battery according to claim 1 , wherein an average thickness of the coating portion is in a range of 100 nm to 1000 nm.
