“…The advantages of GPE over traditional liquid electrolytes are that the GPE can provide better homogeneity of Zn 2+ migration, minimizing the dendrite formation, higher dielectric constant and higher transference number [5,39] . Most recently published articles studied aqueous‐based GPEs, whilst nonaqueous‐based GPEs (NAQ‐GPEs) receive less attention [38a] . However, despite aqueous‐based GPEs exhibiting better mass transport than NAQ‐GPEs, most NAQ‐GPEs show wider operating temperatures.…”

Owing to their high energy density and low cost, zinc‐ion batteries (ZIBs) are gaining much in popularity. However, in practice, issues with hydrogen evolution, zinc dendrite development, corrosion, and passivation persist. Such drawbacks prove difficult to eradicate completely. To address these difficulties, many techniques have been proposed including inhibitor addition, artificial SEI, and Zn electrode modification. As a result, some researchers believe that using non‐proton donor electrolytes or nonaqueous electrolytes can fundamentally solve these problems. Herein, the efforts to apply nonaqueous electrolytes such as organic electrolytes, room‐temperature ionic liquids, and deep‐eutectic solvents to ZIBs are described. An understanding of the mechanisms of nonaqueous ZIBs (NZIBs) regarding zinc plating/stripping and intercalation/deintercalation is also highlighted. Importantly, research gaps are identified in order to pave the way for future study. In addition, an attempt is made to offer a viewpoint on critical topics as well as a benchmarking and enhancement of NZIB technologies.

“…In the dry powder form, the positively charged sodium ions are bonded to the polyacrylate; however, in aqueous solutions, the sodium ions can be dissociated. Instead of the formation of an organized polymer chain, this leads to a swollen gel that can absorb a high amount of water [38].…”

This study recommends Carbopol/zinc oxide (ZnO) hybrid nanoparticles gel as an efficient antibacterial agent against different bacterial species. To this end, ZnO nanoparticles were synthesized using chemical precipitation derived from a zinc acetate solution with ammonium hydroxide as its precipitating agent under the effect of ultrasonic radiation. The synthesized ZnO nanoparticles were stabilized simultaneously in a freshly prepared Carbopol gel at a pH of 7. The chemical composition, phase identification, particle size and shape, surface charge, pore size distribution, and the BET surface area of the ZnO nanoparticles, as well as the Carbopol/ZnO hybrid Nanoparticles gel, were by XRD, SEM, TEM, AFM, DLS, Zeta potential and BET instruments. The results revealed that the synthesized ZnO nanoparticles were well-dispersed in the Carbopol gel network, and have a wurtzite-crystalline phase of spherical shape. Moreover, the Carbopol/ZnO hybrid nanoparticles gel exhibited a particle size distribution between ~9 and ~93 nm, and a surface area of 54.26 m2/g. The synthesized Carbopol/ZnO hybrid nanoparticles gel underwent an antibacterial sensitivity test against gram-negative K. pneumonia (ATCC 13883), Bacillus subtilis (ATCC 6633), and gram-positive Staphylococcus aureus (ATCC 6538) bacterial strains, and were compared with ampicillin as a reference antibiotic agent. The obtained results demonstrated that the synthesized Carbopol/ZnO hybrid nanoparticles gel exhibited a compatible bioactivity against the different strains of bacteria.

“…Solid electrolytes can make batteries much safer, not only because they prevent liquid electrolytes leaks which are potentially toxic or corrosive, but mainly because they mitigate or avoid dendrite growth and subsequent short-circuits. Dendrite growth occurs not only in Li batteries [ 1 ], but also in Na [ 2 ], Al [ 3 ], Ca [ 4 ] and Zn [ 5 ] ones (only apparently not in Mg [ 6 ]), and thus its mitigation is of interest for a broad battery community. Debate as to the mechanism which impedes the growth of metallic dendrites has taken place in the past.…”

Addressing Manufacturability and Processability in Polymer Gel Electrolytes for Li/Na Batteries

Gel electrolytes are prepared with Ultra High Molecular Weight (UHMW) polyethylene oxide (PEO) in a concentration ranging from 5 to 30 wt.% and Li- and Na-doped 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide (PYR14-TFSI) by a simple procedure consisting of dissolving PEO by melting it directly in the liquid electrolyte while stirring the blend. This procedure is fast, reproducible and needs no auxiliary solvents, which makes it sustainable and potentially easy to scale up for mass production. The viability of the up-scaling by extrusion has been studied. Extrusion has been chosen because it is a processing method commonly employed in the plastics industry. The structure and morphology of the gel electrolytes prepared by both methods have been studied by DSC and FTIR, showing small differences among the two methods. Composite gels incorporation high concentrations of surface modified sepiolite fibers have been successfully prepared by extrusion. The rheological behavior and ionic conductivity of the gels have been characterized, and very similar performance of the extruded and manually mixed gels is detected. Ionic conductivity of all the gels, including the composites, are at or over 0.4 mS cm−1 at 25 °C, being at the same time thermoreversible and self-healing gels, tough, sticky, transparent and stretchable. This combination of properties, together with the viability of their industrial up-scaling, makes these gel electrolyte families very attractive for their application in energy storage devices.
