Capacitive deionization (CDI) is a rapidly emerging desalination technology that promises to deliver clean water while storing energy in the electrical double layer (EDL) near charged surface capacitive format. Whereas most research this subject area has been devoted using CDI for removing salts, little attention paid storage aspect of technology. However, it would allow compete with other processes if could be stored and reused efficiently. This requires operational aspects optimized...
The sugarcane ethanol industry is currently generating an intensive amount of biowaste while consuming significant water resources. In this work, bagasse fly ash (SCBFA), a major with high amounts fixed carbon, employed as precursor for activated carbon (SCBFA-AC) production.

Faradaic deionization (FDI) is an emerging and promising electrochemical technology for stable efficient water desalination. Battery-type energy storage materials applied in FDI have demonstrated to achieve higher salt removal capacities than carbon-based conventional capacitive (CDI) systems. However, most of the reported systems are based on inorganic intercalation compounds that lack cost, safety sustainability benefits, thereby curtailing development a feasible cell. In this work, we...
Capacitive deionization (CDI) has recently gained some degree of popularity as a water treatment technology. This paper demonstrates the benefits coating low surface area carbon electrodes with sub-micron nanoporous layer either γ-Al2O3 or SiO2. As shown by cyclic voltammetry, oxide layer, having pores sizes ranging from larger micro to meso, substantially increased capacitance for ion removal while still maintaining reasonably high ohmic conductivity. The amount Ca2+ removed in CDI cell...
Metal oxide coated carbon materials were shown to have increased ion removal over many of the uncoated carbons when used in capacitive deionization; however, influence coating was dependent on material as substrate.

Water scarcity, driven by climate change and population growth, necessitates innovative desalination technologies. Conventional methods for brackish water are limited high‐energy demands, especially in the low salinity range, prompting exploration of electrochemical approaches like faradaic deionization. Sodium‐manganese oxides, traditionally used sodium‐ion batteries, show promise as deionization electrode materials due to their abundance, toxicity, cost‐effectiveness. However, capacity...
