Apparatus, systems, and methods described herein relate to the manufacture and use of single pouch battery cells. In some embodiments, an electrochemical cell includes a first current collector coupled to a first portion of a pouch, the first current collector having a first electrode material disposed thereon, a second current collector coupled to a second portion of the pouch, the second current collector having a second electrode material disposed thereon, and a separator disposed between the first electrode material and the second electrode material. The first portion of the pouch is coupled to the second portion of the pouch to enclose the electrochemical cell.
