1. An all-solid secondary battery comprising:
a cathode layer comprising a cathode active material layer;
an anode layer; and
a solid electrolyte layer disposed between the cathode layer and the anode layer,
wherein the anode layer comprises an anode current collector and a first anode active material layer disposed on the anode current collector,
wherein the first anode active material layer comprises an organic electrolyte and an anode active material that is capable of forming an alloy with lithium or a compound with lithium,
wherein the anode active material comprises at least one of a carbon-containing anode active material, a metal anode active material, or metalloid anode active material,
wherein the first anode active material layer comprises the organic electrolyte in a range from about 0.1 parts by weight to about 2.5 parts by weight, based on 100 parts by weight of the anode active material,
wherein the organic electrolyte comprises an organic salt comprising an organic cation and an anion, and
wherein the organic cation comprises a heterocyclic cation comprising 1 to 3 heteroatoms.
