1. An electrochemical device, comprising:
a first electrochemical cell having a first electrolyte layer between a first anode layer and a first cathode layer in a stack direction, wherein the first anode layer includes an anode contact region and an anode current collector contact region, and wherein the anode contact region is offset in the stack direction from the anode current collector contact region; and a second electrochemical cell having a second electrolyte layer between a second anode layer and a second cathode layer, wherein the second anode layer contacts the first anode layer at the anode contact region; and an anode current collector tab in contact with the first anode layer at the anode current collector contact region.
