Abstract

Capacitive Deionization (CDI) is a non-energy intensive water treatment technology. To harness the enormous potential of CDI requires improving performance, while offering industrially feasible solutions. Following this idea, the replacement of costly metallic components has been proposed as a mean of limiting corrosion problems. This work explores the use of nanostructured hybrid networks to enable free-form and metal-free CDI devices. The strategy consists of producing interpenetrated networks of highly conductive flexible carbon nanotube (CNT) fibre fabrics and nanostructured metal oxides, {\gamma}Al2O3 and TiO2, through ultrasound-assisted nanoparticle infiltration and sintering. In the resulting hybrids, a uniform distribution of porous metal oxide is firmly attached to the nanocarbon network while the flexibility, high conductivity and low-dimensional properties of the CNTs are preserved. These electrodes present a high porosity ($105 - 118 m^{2} g^{1}$), notably low electrical ($< 0,1 k \Omega cm^{2}$) and low charge transfer resistance (4 {\Omega}), thus enabling the infiltration of aqueous electrolytes and serving as current collector. In this work we built a large asymmetrical cylindrical CDI device solely made of these electrodes and conventional plastics. The cell provides, high average salt adsorption rates of $1.16 mg /g_{AM} min$ ($0.23 mg/g_{CDIunit} min$, low energy consumption ($0.18 Wh/g_{salt}$) and stable electrochemical performance above 50 cycles for brackish water desalination.

Abstract

Vanadium Redox Flow Batteries (VRFBs) are promising candidates for large- scale energy storage applications however, there are still some obstacles that need to be overcome such as their low energy density (25-30 Wh L-1 for a 1.8 M electrolyte), high cost and large environmental impact due to corrosiveness and the unsustainability of vanadium. To address these challenges, we introduce lignin as a low-cost electrocatalyst and capacity booster for the positive electrolyte. Coated on a glassy carbon electrode, lignin showed electrocatalytic abilities and improved the electrochemical reversibility of the VO2+/ redox couple significantly. In charge and discharge cycles volumetric capacities of 28 Ah L-1 (charge) and 23.5 Ah L-1 (discharge) were achieved with a 0.9 M concentrated vanadium electrolyte which surpassed the maximum theoretical capacity of 24.1 Ah L-1 in the charge. This demonstrates an increase of 7.5 Ah L-1 and 9 Ah L-1 for the charge and discharge cycles, respectively, compared to a pristine carbon felt electrode. This work showcases the noteworthy influence of lignin on vanadium and opens new possibilities for VRFB chemistry.
