A current collector layer for an all-solid-state battery is provided with which a good electron path can be easily formed and rate characteristic can be improved. A current collector layerfor an all-solid-state battery, the current collector layerincluding: a carbon material; and a solid electrolyte, the all-solid-state batteryincluding a group 1 or 2 ion conductive solid electrolyte layer, the carbon material being mixed with Si at a weight ratio of 1:1 to produce a mixture, the mixture having an X-ray diffraction spectrum having a ratio of a peak height a to a peak height b, a/b, of 0.2 or more and 10.0 or less as being measured, the peak height a being highest in a range of 2θ of 24° or more and less than 28°, and the peak height b being highest in a range of 2θ of 28° or more and less than 30°.

Collector layer for all-solid-state batteries, all-solid-state battery and carbon material

There is provided an electrode material for electricity storage devices, which enables suppression of heat generation in charge and discharge at large currents. The electrode material for electricity storage devices comprises a first carbon material having a graphite structure wherein graphite is partially exfoliated, and a second carbon material different from the first carbon material, wherein the ratio A/B, where A represents a weight of the first carbon material and B represents a weight of the second carbon material, is within the range of 0.01 or higher and 100 or lower.
