    Abstract: Battery systems according to embodiments of the present technology may include a battery including a first electrode terminal and a second electrode terminal accessible along a first surface of the battery. The battery may define a recessed portion of the battery along the first surface of the battery between the first electrode terminal and the second electrode terminal. The battery systems may include a module electrically coupled with the battery. The module may include a circuit board. The module may include a first conductive tab extending from a second surface of the circuit board opposite the first surface of the circuit board. The first conductive tab may be electrically coupling the module with the first electrode terminal. The module may include a second conductive tab extending from the second surface of the circuit board. The second conductive tab may be electrically coupling the module with the second electrode terminal.

    Abstract: The disclosed technology relates to a looped tab for a battery cell. The looped tab may extend from a set of layers. The looped tab may comprise a first portion adjacent to the set of layers and a second portion adjacent to an inner sidewall of the enclosure. The first portion may comprise a covered portion, the covered portion comprising a metal surface and an oxide coating covering the metal surface, the oxide coating configured to prevent contact between a layer in the set of layers or the enclosure and the metal surface of the covered portion.

    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.
