1. An anode layer for all-solid secondary batteries, the anode layer comprising:
an anode current collector; and
a first anode active material layer on the anode current collector,
wherein the first anode active material layer includes a metal-carbon composite including a metal, carbon, and a polyol, and the metal includes silver, zinc, tin, or a combination thereof, and
wherein, in the metal-carbon composite, a content of the metal is about 3 wt % to about 25 wt %, a content of the carbon is about 55 wt % to about 95 wt %, and a content of the polyol is about 2 wt % to about 40 wt %, based on a total weight of the metal-carbon composite.
