Abstract
A current collector for an electrochemical cell is described. Unlike conventional current collector designs, the current collector does not have an unperforated perimeter frame completely bordering or surrounding a perforated interior region. Instead, only that portion of the current collector adjacent to the connector tab is unperforated. Otherwise, perforations extend directly to the perimeter edge.
