The exemplary embodiments provides a desalination device comprising an electrochemical cell comprising a porous positive electrode, a porous negative electrode, and a membrane positioned between the porous positive electrode and the porous negative electrode, the electrodes comprising a network of conductive material comprising a plurality of electrode active materials dispersed throughout the conductive material, the porous negative electrode and the porous positive electrode have the same electrode active material, a power supply to supply a current to the electrochemical cell, an inlet for providing a feed stream to the electrochemical cell, a first outlet line for removing a concentrated effluent and a second outlet line for removing a desalinated effluent. Also provided is a desalination device having a plurality of electrochemical channels with alternating anion and cation selective membranes, and a porous negative and positive electrode having the same electrode active material.

The flow cell includes first and second reservoirs having a selected volume containing a flowable redox electrode. A membrane separates charged and discharged material. An energy-extraction region includes electronically conductive porous current collectors through or adjacent to which the flowable redox electrodes flow and to which charge transfer occurs. Structure is provided for altering orientation of the flow cell whereby gravity induces flow of the flowable redox electrode between the first and second reservoirs to deliver power. By varying the angle of the cell, flow rate and power delivered on discharge or the charge rate on charge may be varied.
