▎ 摘　　要

NOVELTY - Split electrode comprises an electrode formed on one surface of a current collector, and a multiple of channels are capable of inducing the flow of electrolyte patterned in a lattice pattern on the surface of the electrode, where the channel meets the equation W equal to 10-100 H, where H is depth of channel and W is width of channel. The electrode comprises an ion exchange resin and an electrode active material. The ion exchange resin is sulfonic acid group, carboxy group, phosphonic group, phosphine group, asonic group, selinonic group, primary amine salt, secondary amine salt, tertiary amine salt and quaternary ammonium salt, and comprising a polymer having at least one ion exchange group of a quaternary phosphonium group and a tertiary sulfonium group. The electrode active material comprises at least one of activated carbon, carbon nanotube, carbon aerogel, graphene, graphite, carbon black, ruthenium oxide, nickel oxide, manganese dioxide, lead(IV) oxide and titanium dioxide. USE - The split electrode is useful in capacitive desalination module for capacitive desalination (claimed), and for various water treatment e.g. seawater, hard water, and wastewater treatment. ADVANTAGE - The split electrode has simple maintenance, and can achieve improvement in filtration efficiency by repeating the filtration of the electrolyte many times by forming a grid patterned channel in the existing electrode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a capacitive desalination module comprising split electrode for capacitive desalination.
