The direct integration occurs during cell manufacturing, which allows sharing components, reducing operation steps and failure points, and reducing cost and size of the circuits. For example, a portion of a cell enclosure may be formed by a circuit board, providing direct mechanical integration. More specifically, the cell is fabricated right on the circuit board. In the same or other examples, one or both cell current collectors extend outside of the cell boundary and used by other devices, providing direct electrical integration without a need for intermediate connections and eliminating additional failure points.
