“…On the one hand, the MA-POSS could enhance the mechanical property, and reduce the flammability and heat release during the combustion of composite material. Meanwhile, the MA-POSS could be more compatible with PMMA and the plasticizer for the existence of organic side chain (MA) [35][36][37][38]. Particularly, GPE exhibited optimized electrochemical performance when the mass ratio of MA-POSS was 10 wt% (Fig.…”

Electrochemical energy storage devices, such as lithium ion batteries (LIBs), supercapacitors and fuel cells, have been vigorously developed and widely researched in past decades. However, their safety issues have appealed immense attention. Gel electrolytes (GEs), with a special state in-between liquid and solid electrolytes, are considered as the most promising candidates in electrochemical energy storage because of their high safety and stability. This review summarized the recent progresses made in the application of GEs in the safety regulation of the electrochemical energy storage devices. Special attention was paid to the gel polymer electrolytes, the organic low molecule-mass GEs, as well as the fumed silica-based and siloxane-based GEs. Finally, the current challenges and future directions were proposed in terms of the development of GEs.

An Overview on Anodes for Magnesium Batteries: Challenges towards a Promising Storage Solution for Renewables

et al. 2021

Magnesium-based batteries represent one of the successfully emerging electrochemical energy storage chemistries, mainly due to the high theoretical volumetric capacity of metallic magnesium (i.e., 3833 mAh cm−3 vs. 2046 mAh cm−3 for lithium), its low reduction potential (−2.37 V vs. SHE), abundance in the Earth’s crust (104 times higher than that of lithium) and dendrite-free behaviour when used as an anode during cycling. However, Mg deposition and dissolution processes in polar organic electrolytes lead to the formation of a passivation film bearing an insulating effect towards Mg2+ ions. Several strategies to overcome this drawback have been recently proposed, keeping as a main goal that of reducing the formation of such passivation layers and improving the magnesium-related kinetics. This manuscript offers a literature analysis on this topic, starting with a rapid overview on magnesium batteries as a feasible strategy for storing electricity coming from renewables, and then addressing the most relevant outcomes in the field of anodic materials (i.e., metallic magnesium, bismuth-, titanium- and tin-based electrodes, biphasic alloys, nanostructured metal oxides, boron clusters, graphene-based electrodes, etc.).

A novel catalytic nanocomposite, MNPs/Hal‐POSS‐HEMA‐Pd, composed of halloysite nanoclay and polyhedral oligomeric silsesquioxane is reported. To synthesize the catalyst, magnetic halloysite was vinyl functionalized and then polymerized with 2‐hydroxyethyl methacrylate and methacrylate polyhedral oligomeric silsesquioxane. Afterwards, the latter was palladated to furnish a heterogeneous catalyst with use for catalyzing the reductive degradation of organic dyes, Rhodamine B, and methyl orange with NaBH4. The kinetic and thermodynamic parameters of both reactions were estimated. The results asserted that low content of the catalyst could catalyze the dye reduction reactions to furnish hydrogenated product in quantitative conversion in a very short reaction times (1 min). It is assumed that both halloysite and polyhedral oligomeric silsesquioxane can contribute to the anchoring of Pd nanoparticles. On the other hand, the polymeric network around halloysite can furnish a microenvironment for bringing dyes in the vicinity of active sites. Moreover, unique tubular morphology of halloysite can effectively improve dye adsorption and consequently enhance dye reduction. Additionally, the study of the recyclability of the catalyst approved that it could be magnetically recovered and reused for ten successive reaction runs with trivial leach of Pd (2 wt.%) and decrement of the catalytic activity.
