Capacitive Deionization (CDI) is an emerging technology for the removal of charged ionic species from aqueous solutions and has been widely explored for water desalination applications. The technology is based on reversible salt adsorption–desorption at porous carbon electrodes.  To achieve optimal desalination, CDI electrodes would possess high electrical conductivity, large surface area, good wettability and porous structure for ion and electron transportation.
CDI hardware components include current collector plates (graphite) which assemble electrodes and membranes into the cell and provide channels for flowing electrode slurry.  A set of gaskets provide an aqueous solution compartment and sealing for membranes and electrodes.​
