“…This could be attributed to the passivation of the anode surface, found at the end of the batch test due to either the dissolution of aluminum or the directly oxidized film formed on the electrode. Passivation affects the polarization resistance causing lower cell potential than the theoretical value [52]. The passive film, indeed, increases the resistance and reduces the release of the coagulant and bubbles, decreasing the current and removal efficiency [53].…”

Abstract:The continuous release of emerging contaminants (ECs) in the aquatic environment, as a result of the inadequate removal by conventional treatment methods, has prompted research to explore viable solutions to this rising global problem. One promising alternative is the use of electrochemical processes since they represent a simple and highly efficient technology with less footprint. In this paper, the feasibility of treating ECs (i.e., pharmaceuticals) using an intermittent electrocoagulation process, a known electrochemical technology, has been investigated. Diclofenac (DCF), carbamazepine (CBZ) and amoxicillin (AMX) were chosen as being representative of highly consumed drugs that are frequently detected in our water resources and were added in synthetic municipal wastewater. The removal efficiencies of both individual and combined pharmaceuticals were determined under different experimental conditions: hydraulic retention time (HRT) (6, 19 and 38 h), initial concentration (0.01, 4 and 10 mg/L) and intermittent application (5 min ON/20 min OFF) of current density (0.5, 1.15 and 1.8 mA/cm 2 ). Results have shown that these parameters have significant effects on pharmaceutical degradation. Maximum removals (DCF = 90%, CBZ = 70% and AMX = 77%) were obtained at a current density of 0.5 mA/cm 2 , an initial concentration of 10 mg/L and HRT of 38 h.

As one of the most promising alternatives to next‐generation energy storage systems, aluminum batteries (ABs) have been attracting rapidly increasing attention over the past few years. In this review, we summarize the recent advancements of ABs based on both aqueous and non‐aqueous electrolytes, with a particular focus on rechargeable non‐aqueous ionic liquid‐based aluminum‐ion batteries (AIBs). Progress of the current intensive investigation on the development of cathode materials and electrolytes in non‐aqueous AIBs are discussed. Then research efforts towards aqueous ABs are described to give readers a broader view of the aluminum battery family. Finally, the review summaries the key challenges underpinning ABs and provides future research perspectives on this growing field.

“…However, most of the solid electrolytes exist in bulk and possess rigid physical properties which reduce the energy density of the battery. Therefore, it is necessary to search for a more suitable solid electrolyte for the aluminium-air battery (Zhang et al, 2014;Pino et al, 2015;Di Palma et al, 2017). In view of this, Wang et al (2019a) introduced the paper-based solid electrolyte to produce low-cost aluminiumair batteries.…”

Global energy demand is rising due to the rapid development and adoption of new technologies in every sector. Hence, there is a need to introduce a clean energy source that does not cause damage to the environment. Aluminium-air battery with its high theoretical specific volumetric capacity is an exciting alternative for post-lithium energy storage and has been at the forefront of energy research for years. However, the conventional aqueous electrolyte-based aluminium-air battery with bulky liquid storage, parasitic corrosion of aluminium in contact with the electrolyte, and formation of a passive oxide or hydroxide layer has precluded its widespread application. In order to achieve successful simplification and cost-effectiveness, a novel idea of a polypropylene-based aluminium-air battery is proposed. In this work, a polypropylene-based aluminium-air battery was constructed using aluminium foil as an anode, carbon fiber cloth as an air-cathode, and Polypropylene and Kimwipes as the separator. The effects of the electrolyte concentration on the aluminium-air battery were investigated and analyzed using various discharge currents. The study showed that the performance of the polypropylene separator is better than that of the Kimwipes separator. The battery capacity is negatively correlated with the concentrations of the electrolyte. At a discharge current of 30 mA, the aluminium-air battery has a specific capacity of 375 mAh g−1 when 1 M of potassium hydroxide was used as electrolyte.
