1. An all-solid-state secondary battery comprising:
a cathode comprising a cathode active material layer;
an anode comprising
an anode current collector, and
an anode active material layer on the anode current collector, wherein the anode active material layer comprises an anode active material comprising
a first particle comprising amorphous carbon, and
a second particle comprising at least one of a metal or a semiconductor, wherein an amount of the second particle is about 8 weight percent to about 60 weight percent, based on a total weight of the first particle and the second particle, and
a binder;
a solid electrolyte layer between the cathode and the anode; and
a metal layer between the anode active material layer and anode current collector, wherein the metal layer comprises at least one of lithium or a lithium alloy.
