Abstract
An electrode having a notch along one edge is provided. The notch prevents unintentional internal shorting between the electrode and internal cell structures having an opposing polarity. In a preferred embodiment, the electrode is used in jellyroll electrochemical cells to avoid contact between the most exterior electrode wrap of the jellyroll and the can. A method of making such an electrode from a continuous strip of electrode material is also provided.
