Metal−organic materials (MOMs) are receiving widespread interest for use in many energy-related applications due to their tunable structure attained by the deliberate selection of metal and ligand components and their associated structure− property relationships. In this work, we demonstrate the dimensional crossover of discrete metal−organic polyhedra, CuMOP-3 (0-D, [Cu 24 (5-sip) 24 (S) 24 ]•xS; 5-sip = 5-sulfoisophthalic acid, C 8 O 7 H 5 S), into Cu-based coordination polymers, CuCP-1 (2-D, [Cu(Im) 4 •Cu 2 (Im) 4 (5-sip) 2 ]•2CH 3 OH) and CuCP-2 (3-D, [Cu 4 (μ 3 -OH) 2 (Im) 2(5-sip) 2 ]•2H 2 O), using the coordinative guest (imidazole (Im, C 3 N 2 H 4 ) and H 2 O) insertion method. Specifically, the variation in the coordination environment at the metal center and secondary building units (SBUs) in response to these guest molecules as well as the changes in the coordination mode of the sulfonate (R-SO 3 − ) functional group in the hemilabile 5-sip ligand induced overall structural and dimensionality changes. Furthermore, the transformation of dimensionality resulted in materials having improved thermal and chemical stabilities along with other physical properties (gas sorption and proton conductivity). This study introduces a new design strategy for achieving dimensional crossover in MOMs by involving both hemilabile organic linkers and coordinative guest insertions.

“…In addition, their compatibility with various metals makes them adaptable for use in diverse metal-air battery systems [8]. However, their relatively lower ionic conductivity compared to liquid systems limits the power output of these batteries, requiring the incorporation of organic/inorganic phases that provide the matrix with the ions capable of performing the conduction process [9]. Hence, the benefits of gel-type polymer electrolyte systems (GPEs) arise from their combination of the favorable attributes found in liquid-type electrolytes, like their high ionic conductivity, and solid-state electrolytes, diminishing the high interface resistance [10,11].…”

Meeting the ever-increasing global energy demands through sustainable and environmentally friendly means is a paramount challenge. In response to this imperative, this study is dedicated to the development of biopolymer electrolytes, which hold promise for improving the efficiency, safety, and biodegradability of energy systems. The present study aims to evaluate hydrogels synthesized from chitosan biopolymer and starch from avocado seed residues in different ratios, and dried using freeze-thawing and freeze-drying techniques. Epichlorohydrin was used as a chemical crosslinker to create a suitable degree of swelling using an ionic solution. Physical freezing crosslinking strategies such as freezing–thawing and freezing–drying were performed to generate a denser porous structure in the polymer matrix. Subsequently, synthesized electrolytes were immersed in 12 M KOH solution to improve their electrochemical properties. The effect of the different ratios of starch in the hydrogels on the structural properties of the materials was evaluated using characterization techniques such as FTIR and XRD, which allowed to confirm the crosslinking between chitosan and starch. The electrochemical performance of the hydrogels is assessed using electrochemical impedance spectroscopy. A maximum conductivity value of 0.61 S·cm−1 was achieved at room temperature. The designed materials were tested in prototype zinc–air batteries; their specific capacity value was 1618 mA h·g−1, and their obtained power density was 90 mW·cm−2. These substantial findings unequivocally underscore the potential of the synthesized hydrogels as highly promising electrolytes for the application in zinc–air battery systems.

Solid polymer electrolytes (SPEs) for lithium metal batteries have garnered considerable interests owing to their low cost, flexibility, lightweight, and favorable interfacial compatibility with battery electrodes. Their soft mechanical nature compared to solid inorganic electrolytes give them a large advantage to be used in low pressure solid‐state lithium metal batteries (SSLMBs), which can avoid the cost and weight of the pressure cages. However, the application of SPEs has been hindered by their relatively low ionic conductivity. In addressing this limitation, enormous efforts have been devoted to the experimental investigation and theoretical calculations/simulation of new polymer classes. Recently, metal‐organic frameworks (MOFs) have been shown to be effective in enhancing ion transport in SPEs. However, the mechanisms in enhancing Li+ conductivity have rarely been systematically and comprehensively analyzed. Therefore, this review provides an in‐depth summary of the mechanisms of MOF‐enhanced Li+ transport in MSPEs in terms of polymer, MOF, MOF/polymer interface (MPI) and solid electrolyte interface (SEI) aspects, respectively. Moreover, the understanding of Li+ conduction mechanisms through employing advanced characterization tools, theoretical calculations and simulations are also reviewed in this review. Finally, the main challenges in developing MSPEs are deeply analyzed and the corresponding future research directions are also proposed.This article is protected by copyright. All rights reserved
