Researchers from our institute have developed in collaboration with IMDEA Energy a new current collector-free  capacitive deionization architecture based on electrodes consisting of a porous metal oxide network interpenetrated into porous fibres of carbon nanotube. The full device has a large salt adsorption capacity and very high efficiency of 86%, which translates into a low energy consumption per gram of salt removed. His discovery has recently been published in  Journal of Materials Chemistry A journal.
