Abstract
An electrochemical cell and an electrode for use in an electrochemical cell is provided. The electrochemical cell has a container, a positive electrode disposed in the container and having a wall defining an interface surface, a negative electrode disposed in the container, a separator located between the positive and negative electrodes, and an electrolyte. The second electrode has a unitary piece of electrochemically active material having multiple openings formed in a circumferential surface. The unitary piece may include a slotted tube, first and second members, or a coiled strip.
