Abstract
An electrochemical cell includes an electrode assembly disposed in a cell housing. A first U-shaped current collector is disposed between the cell housing and the electrode assembly, and is electrically connected to a positive electrode portion of the electrode assembly. A second U-shaped current collector is disposed between the cell housing and the electrode assembly, and is electrically connected to a negative electrode portion of the electrode assembly. The first and second current collectors cooperate to surround all sides of the electrode assembly and to retain the electrode assembly in the desired configuration without requiring a separate restraint.
