Abstract: Disclosed herein are systems, devices, and methods for a hybrid electrochemical cell which utilizes two different chemistries in the same cell. According to one aspect, the hybrid cell includes a first pair of electrode units which form a first electrochemical cell and a second pair of electrode units, which form a second electrochemical cell. The second electrochemical cell utilizes a different chemistry than the first electrochemical cells, but both chemistries share a common electrolyte. The hybrid cell further comprises a common electrolyte layer provided between each pair of electrodes. In certain implementations, the common electrolyte layer is a single cavity such that the electrolyte is shared between both the first and the second electrochemical cell.
