Abstract
Official abstract text for this publication.
An anode mixture with high energy density and capability of restraining the decrease in capacity maintaining rate due to the expansion and contraction of an anode active material is provided. The anode mixture includes a first anode active material, a second active material and a solid electrolyte material. The first anode active material is an active material having a carbon matrix and a particle containing Si or Sn dispersed into the carbon matrix. An average particle diameter of the first anode active material is 15 μm or less and a content of the carbon matrix in the first anode active material is 15% by weight or more and 65% by weight or less. A content of the particle in the first anode active material is 35% by weight or more and 85% by weight or less and has an average particle diameter of 11 nm or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. An anode mixture comprising a first anode active material, a second anode active material, and a solid electrolyte material, wherein the first anode active material is an active material having a carbon matrix and particles containing Si or Sn dispersed into the carbon matrix, an average particle diameter of the first anode active material is 15 μm or less, a content of the carbon matrix in the first anode active material is 15% by weight or more and 65% by weight or less, a content of the particles in the first anode active material is 35% by weight or more and 85% by weight or less, an average particle diameter of the particles is 11 nm or less, the second anode active material is a carbon material, and a ratio of the first anode active material relative to a total of the first anode active material and the second anode active material is 20% by weight or more and 90% by weight or less. 2. The anode mixture according to claim 1 wherein a surface of the first anode active material is coated with a lithium oxide. 3. An all solid battery comprising an anode active material layer including the anode mixture according to claim 1 . 4. The anode mixture according to claim 1 wherein an average particle size of the second anode active material is 50 μm or less. 5. The anode mixture according to claim 1 wherein the solid electrolyte material is a sulfide solid electrolyte material.
