The present invention relates to a positive electrode composite mounted on an all-solid battery, comprising: a metal current collector as a passage through which electrons are received from the outside and electrons inside is supplied to the outside; a positive electrode composite in surface contact with the metal current collect and containing an electrolyte, a positive electrode active material, and a conducting agent; and an electrolytic layer in contact with the positive electrode composite to be symmetrical to the metal current collector, wherein the contents of the electrolyte, the positive electrode active material, and the conducting agent are varied in a non-linear manner toward the metal current collector, and thus, the closer the electrolytic layer, the higher the ion conductivity, and the closer the metal current collector, the higher the electron conductivity, so an active electrochemical reaction is expressed in all spaces constituting the inside of the positive electrode composite. |
