Prismatic Cell With Outer Electrode Layers Coated On A Single Side

Abstract

Embodiments of the present invention provide an electrochemical cell including a stack of electrode layers and separator layers. The electrode layers include anode layers and cathode layers disposed in an alternating manner and separated by the separator layers. The two outer electrode layers of the stack are of the same type and are coated with an active material on an inward-facing surface only. The electrochemical cell may include two or more insulating layers disposed at the two ends of the electrode stack, and a pouch enclosing the electrode stack and the insulating layers.
