Abstract: Energy storage devices, battery cells, and rechargeable batteries according to some embodiments of the present technology may include an enclosure, and an electrode stack housed within the enclosure. The batteries may include a negative electrode terminal electrically coupled with the electrode stack and disposed on an external surface of the enclosure. The batteries may include a positive electrode terminal electrically coupled with the electrode stack and disposed on an external surface of the enclosure. The batteries may include an electrolyte incorporated within the enclosure. The batteries may also include a reference electrode at least partially in contact with the electrolyte. The reference electrode may be disposed on an external surface of the enclosure, and may be electrically isolated from the negative electrode terminal and the positive electrode terminal.
