Energy storage devices, battery cells, and batteries of the present technology may include a first circuit board characterized by a first surface and a second surface opposite the first surface. The second surface may include a conductive layer. The batteries may include a battery stack overlying the first circuit board and electrically coupled with the second surface of the first circuit board. The battery stack may include a plurality of battery cells. The batteries may include a second circuit board overlying the battery stack. The second circuit board may be characterized by a first surface and a second surface opposite the first surface. The second surface may include a conductive layer, and the battery stack may be electrically coupled with the second surface of the second circuit board. The batteries may include a power distribution block electrically coupled with the first and second circuit boards.

Battery configurations having balanced current collectors

Energy storage devices, battery cells, and batteries of the present technology may include a first cell and a second cell disposed adjacent the first cell. The devices may include a stacked current collector coupled between the first cell and the second cell. The current collector may include a grid or matrix, and may include a combination of conductive and insulative materials.
