全固体電池用負極
Document Type and Number:
Japanese Patent JP6497282
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a negative electrode for an all-solid battery, by which an all-solid battery having both of a high cell volume energy density and a superior capacity-keeping rate can be obtained.SOLUTION: A negative electrode for an all-solid battery comprises: a sulfide solid electrolyte; and a negative electrode active material. The negative electrode active material includes complex particles having a carbon material including Si or Sn. The particle diameter of Si or Sn is 94 nm or less, and the particle diameter of the negative electrode active material is 15 μm or less. The negative electrode has a porosity of 5-30%.SELECTED DRAWING: Figure 1
