Abstract: To make a pouch format cell, an outermost stack (including a negative electrode and separators positioned on opposed surfaces thereof) is formed. An inner stack is formed, including a positive electrode and a sub-stack (i.e., another negative electrode with separators positioned on opposed surfaces thereof and another positive electrode). The inner stack is positioned on the outermost stack to form a core stack, such that i) one inner stack end substantially aligns with one outermost stack end, ii) another end and a portion of the outermost stack remain exposed, and iii) the inner stack positive electrode is adjacent to one of the outermost stack separators. The outermost stack exposed portion is folded around another inner stack end and to cover a portion of an outer layer of the inner stack. This forms an initial overlay. The core stack is folded around at least a portion of the initial overlay.

Abstract: In an example of a method for preparing a coated lithium battery component, the lithium battery component is selected from the group consisting of a porous membrane, a positive electrode, and a negative electrode. The lithium battery component is coated with a precursor. The precursor includes a mixture of an electrolyte solvent, a lithium compound, and a monomer. Coating the lithium battery component forms a precursor coating on the lithium battery component. The precursor coating on the lithium battery component is exposed to a plasma jet, which causes the polymerization of the precursor to form a polymer coating on the lithium battery component.
