SYSTEMS AND METHODS FOR A STAGGERED INTRODUCTION MULTILAYER POUCH CELL

Methods and systems are provided for manufacturing a staggered introduction multilayer pouch wherein the staggered introduction multilayer pouch is configured to release chemicals into a pouch cell battery on demand during formation, aging and testing (FA&T). In one example, a system may include a main pouch and one or more chemical pouches adjacent to the main pouch. The main pouch may include an electrode stack and include a cathode tab and an anode tab and the chemical pouches may be configured to add chemicals to the main pouch on demand. In some examples, the chemical pouches may contain electrolytes or other additives that can be added to the main pouch on demand according to the FA&T process and the chemical properties of each chemical.
