Abstract
An insulator structure forming a physical barrier encapsulating the entire electrode assembly including all the positive portions and segregating them from the negative leads and the casing is described. By completely encapsulating the electrode assembly including the cathode lead portions from the anode leads and the casing, no opposite polarity structures that can potentially serve as a surface for lithium bridging are left exposed to electrolyte.
