Electrode for capacitive deionization in which fabrics of CNT (carbon nanotube) fibres and metal oxides hybridise forming interconnected porous networks, thus comprising a single element, i.e. a hybrid material. The fabrication of electrodes is based on the continuous impregnation of CNT fibres with metal oxide precursors in-line as they are spun from the chemical vapour deposition reaction, followed by thermal treatment (350ºC). Consequently, the electrode of the present invention has a reduced contact resistance and improved charge capacitance which leads to more efficient capacitive deionization systems.
The hybrid electrode presents a better performance as a result of the synergistic effect between both components of the hybrid material, i.e. the CNT fibres and the metal oxide coating. The fibres of CNT constitute a flexible network that guarantees not only textural and electrochemical properties of interest for capacitive deionization but also, ensures such a high electrical conductivity, that allows to discard the use of expensive current collectors and thus to stablish a direct electrical contact between the electrode and the external power source.
They are looking for potential partners from the agrofood, environmental and materials sectors to establish license agreements, preferably industry, and research cooperation agreements also open to academic and other research organisations.
