    Abstract: Batteries according to embodiments of the present technology may include a housing including a first terminal disposed on a first side of the housing and a second terminal disposed on the first side of the housing. The batteries may include an electrode stack positioned within the housing. The electrode stack may include an anode current collector. The anode current collector may define an anode tab along a first side of the anode current collector, and be electrically coupled with the first terminal. The electrode stack may include a cathode current collector. The cathode current collector may define a cathode tab along a second side of the cathode current collector. The cathode tab may extend from the cathode current collector in a direction normal to a direction the anode tab extends from the anode current collector. The cathode tab may be electrically coupled with the second terminal.

    Abstract: Energy storage devices, battery cells, and batteries may include a first current collector having an anode active material disposed along a first surface of the first current collector. The cells may include a plurality of first electrodes positioned along a second surface of the first current collector opposite the first surface. The plurality of first electrodes may be characterized by a first orientation. The cells may include a second current collector having a cathode active material disposed along a first surface of the second current collector. The cells may include a separator positioned between the anode active material and the cathode active material. The cells may also include a plurality of second electrodes positioned along a second surface of the second current collector opposite the first surface. The plurality of second electrodes may be characterized by a second orientation substantially orthogonal to the first orientation.
