Abstract
An anode-free cell including a housing and a plurality of cathode layers each cathode layer includes a cathode current collector disposed between two cathode active material layers. The anode-free cell also includes a pair of separators, and an anode current collector laminated in between the pair of separators to form a continuous laminated separator-current collector-separator layer. The continuous laminated separator-current collector-separator layer is positioned in between adjacent cathode layers of the plurality of cathode layers in a continuous stacking fold.
