Electrode for an all solid state battery, and an anodeless all solid state battery including the same

An anodeless all solid state battery comprising:

• an anode current collector;
• an intermediate layer including a carbon structure and disposed on the anode current collector;
• a solid electrolyte layer disposed on the intermediate layer;
• a cathode active material layer including a cathode active material and disposed on the solid electrolyte layer;
• and
• a cathode current collector disposed on the cathode active material layer,
• wherein the carbon structure includes:
• a plurality of base bodies arranged with separation spaces formed between adjacent base bodies among the plurality of base bodies,
• wherein a diameter (D50) corresponding to 50% of a cumulative volume in a cumulative volume distribution of a base body is in a range of 5 μm to 12 μm, and
• wherein a full width at half maximum width (FWHM 2θ) of a (002) peak is in a range of 0.3° to 0.8°, when an X-ray Diffraction (XRD) analysis is performed with respect to the carbon structure.

A method for manufacturing an electrode for an all solid state battery, the method comprising:

• separating a base body from a carbon material by applying energy to a mixture solution in which the carbon material and a polymer binder are solved, and rearranging a result structure through self-assembling;
• and
• preparing a carbon structure by ball-mill grinding the result structure in a range of 55 minutes to 150 minutes,
• wherein a full width at half maximum width (FWHM 2θ) of a (002) peak is in a range of 0.3° to 0.8°, when an X-ray Diffraction (XRD) analysis is performed with respect to the carbon structure.
