The present invention relates to an all-solid-state battery including: a battery supporting member including an oxide-based solid electrolyte of a garnet structure; a positive electrode disposed on a first surface of the battery supporting member; and a negative electrode disposed on a second surface of the battery supporting member, wherein the positive electrode includes: a positive active material layer in contact with the first surface of the battery supporting member and including a positive active material represented by a predetermined chemical formula, and an ion conductor; and a positive current collector disposed on the positive active material layer, a manufacturing method thereof, a secondary battery including the same, and a monolithic battery module including the same.

All-solid-state battery, manufacturing method therefor, secondary battery comprising same and monolithic battery module comprising same

Provided are a silicon oxide-carbon composite, a method of preparing the same, and an energy storage device containing the same. In the method of preparing a silicon oxide-carbon composite, a reaction solution containing an organic solvent including an aromatic compound is provided. Crystalline carbon structures are formed by generating plasma in the reaction solution. A slurry is formed by adding silicon halide and a polyol in the reaction solution in which the crystalline carbon structures are dispersed. The slurry is separated from the organic solvent and subjected to thermal treatment.
