Abstract
A lithium ion battery electrode, cell, or module, and a method and apparatus for making the same, is provided. The cell includes a first electrode foil having a first body and a first tab. The first body has long edges defining a length, and short edges defining a width. A length-to-width ratio of the first body is at least two, but may be at least five. The first tab extends from one of the long edges of the first body, and is entirely between one of the short edges of the first body and a midpoint of the long edge. A first coating is formed of one of an anodic material and a cathodic material, and substantially covers and least one side of the first body of the first electrode foil.
