Summary: This Perspective highlights the pathways to prepare porous ionic liquids using easily accessible materials for reduced environmental impact. The study demonstrates that suspensions of porous solids are stable in eutectic mixtures, which indicates their potential in preparing porous ionic liquids. Porous ionic liquids maintain the wide electrochemical window observed in their precursor pure ionic liquids, making them suitable for green electrochemical reactions, especially those involving gases with enhanced solubility in the porous suspensions. Furthermore, their capacity as gas-rich media suggests potential sustainable biomedical and pharmaceutical applications, provided that non-toxic, biocompatible ionic liquids and porous solids are utilized.

Summary: A series of cyanines with varying methine chain lengths and terminal groups were reacted with a specific cation after excitation in the NIR region, resulting in the generation of free radicals and conjugate acids. This study investigated the efficiency of free radical and cationic polymerization, as well as their combination as a hybrid system. By using NIR-LED exposure and varying the sensitizers, different photopolymerization efficiencies were achieved. The results showed that the combination of free radical and cationic polymerization can work effectively in hybrid systems.

Summary: In this study, we investigate the influence of ionic correlations on the reaction rates and selectivity of CO2 electroreduction. Through experiments, we find that at intermediate concentrations, the reduction rates of CO2 are accelerated and the efficiency of CO production is enhanced. The acceleration of CO2 reduction is due to the amplification of potential-dependent driving forces, rather than changes in onset potential. These findings are applicable to both cocatalytic and noncatalytic ions.

Summary: The interactions between counterions and electronic carriers in electrically doped semiconducting polymers play a crucial role in charge carrier delocalization, electronic conductivity, and thermal stability. Introducing dianions in semiconducting polymers leads to double doping, minimizing structural distortions but altering the electrostatic interactions. Polymeric ionic liquids (PILs) with croconate dianions prove useful in studying the role of counterions in p-type semiconducting polymers, preventing cation diffusion during ion exchange. The choice of croconate dianions influences the thermoelectric performance and thermal stability of the doped semiconducting polymer.

Summary: We investigated the sodium electrochemistry and the evolution and chemistry of the solid-electrolyte interphase (SEI) during cycling of Na metal electrodes in two ionic liquid (IL) electrolytes. We found that the IL based on the phosphonium cation demonstrated superior performance and stability compared to the pyrrolidinium-based counterpart, even after the addition of water. This research breakthrough shows promise for the development of high-capacity Na metal anodes and future higher-temperature Na-metal-based batteries.

Summary: The relationship between formation procedure and interfacial characteristics of electrodes in sodium-ion batteries is crucial for cell performance. We successfully shortened the formation time and improved the cycling performance of the sodium-ion half cell through optimized formation protocols in superconcentrated ionic liquid electrolytes. Our findings show that high C-rate formation contributes to a highly conductive and thinner solid-electrolyte interphase (SEI) layer, facilitating Na+ diffusion kinetics. This work provides a cost-effective and time efficient formation protocol for NIBs.

Summary: In order to utilize the advantages of high energy density lithium-metal batteries, their cycle life and safety need to be improved. External compression has been shown to enhance the performance of these batteries by reducing dendrite growth and improving lithium deposition morphology. This study investigates the behavior of high-capacity Li||LFP pouch cells in pyrrolidinium-based ionic liquid electrolytes under different levels of compression and discusses the mechanisms that affect the cell performance and failure. The results indicate that higher compression leads to more uniform and less dendritic lithium deposition.

Summary: Transdermal monitoring and drug delivery have attracted attention due to the development of minimally invasive microneedle (MN) devices. Recent research has focused on incorporating conducting polymers (CPs) onto MNs, but the biocompatibility of CPs in skin and the effects of electrical biasing on cells have not been extensively studied. This study found that cells cultured at a low seeding density exhibited lower viability and proliferation after exposure to electrochemically biased MNs comprising PEDOT polymers.

Summary: Ion transport in composite electrodes is crucial for the performance of lithium-metal batteries, and the use of ionic conducting polymers as binders has been suggested. In this study, two poly(ionic liquid) polymers were analyzed as binders in LiFePO4 cathodes, and PMTFSI-Li showed the best performance with high specific capacity and long lifespan. Surprisingly, the presence of ionic binders also affected the lithium metal deposition morphology, leading to a more homogeneous plating and mitigating mossy lithium growth.
