The method includes forming a pair of electrosorptive electrodes, forming 2 a spacer compartment including a spacer layer and forming surface plates. The electrosorptive electrodes, the spacer compartment and the surface plates are assembled to form a flow channel for water treatment with the spacer compartment being arranged between the pair of electrosorptive electrodes. The electrosorptive electrodes may be formed by loading a solution of electrosorptive materials or ion-exchange materials into a dis- penser and spraying the solution from the dispenser onto current collec- tors. Alternatively, the electrosorptive electrodes may comprise of two- 58 dimensional (2D) MXene materials.
