“…Compared with the traditional polymers, polymer ionic liquids (PILs)‐based gel electrolytes could be considered as suitable gel electrolytes for SLICs due to the high miscibility between PILs and ILs. Two families of PILs were prepared by Ponkratov via a free radical copolymerization, and a polymer modification followed by ion exchange [44] . The first one could be used as electrolyte because of its satisfactory ionic conductivity while the other one was applied as the component of the electrode films due to the adequate formability.…”

Ionic liquids are considered to be promising electrolyte solvents or additives for rechargeable batteries (i. e., lithium‐ion batteries, sodium‐ion batteries, lithium‐sulfur batteries, aluminum‐ion batteries, etc.) and supercapacitors. This is related with the superior physical and electrochemical properties of ionic liquids, which can influence the performance of rechargeable batteries. Therefore, it is necessary to write a roadmap on ionic liquids for rechargeable batteries. In this roadmap, some progress, critical techniques, opportunities and challenges of ionic liquid electrolytes for various batteries and supercapacitors are pointed out. Especially, properties and roles of ionic liquids should be considered in energy storage. Ionic liquids can be used as electrolyte salts, electrolyte additives, and solvents. For optimizing ionic liquid‐based electrolytes for energy storage, their applications in various energy storage devices should be considered by combing native chemical/physical properties and their roles. We expect that this roadmap will give a useful guidance in directing future research in ionic liquid electrolytes for rechargeable batteries and supercapacitors.

“…Chemical polymerization of conducting polymers in aqueous solution using hydrophobic PIL as a stabilizer has allowed to make entrapped conducting polymers inside the microparticles [29] for potential applications in OLED [25]. Recently, vapor polymerization of a conducting polymer with PIL was presented, to make materials for supercapacitors [30]. Combinations of zwitter-ionic PILs (PZILs) with covalent linkage to polypyrrole graphene-oxide layers or on gold nanoparticles with polypyrrole nanotubes have been presented for sensor applications [31,32].…”

Improving the Electrochemical Performance and Stability of Polypyrrole by Polymerizing Ionic Liquids

et al. 2020

Polypyrrole (PPy) based electroactive materials are important building blocks for the development of flexible electronics, bio-sensors and actuator devices. As the properties and behavior of PPy depends strongly on the operating environment—electrolyte, solvent, etc., it is desirable to plant immobile ionic species into PPy films to ensure stable response. A premade ionic polymer is not optimal in many cases, as it enforces its own structure on the conducting polymer, therefore, polymerization during fabrication is preferred. Pyrrole (Py) was electropolymerized at low temperature together with a polymerizable ionic liquid (PIL) monomer in a one-step polymerization, to form a stable film on the working electrode. The structure and morphology of the PPyPIL films were investigated by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), Fourier-transform infrared (FTIR) spectroscopy and solid-state NMR (ssNMR) spectroscopy. The spectroscopy results confirmed the successful polymerization of Py to PPy and PIL monomer to PIL. The presence of (TFSI–) anions that balance the charge in PPyPIL was confirmed by EDX analysis. The electrical properties of PPyPIL in lithium bis(trifluoromethanesulfonyl)-imide (LiTFSI) aqueous and propylene carbonate solutions were examined with cyclic voltammetry (CV), chronoamperometry, and chronopotentiometry. The blend of PPyPIL had mixed electronic/ionic conductive properties that were strongly influenced by the solvent. In aqueous electrolyte, the electrical conductivity was 30 times lower and the diffusion coefficient 1.5 times higher than in the organic electrolyte. Importantly, the capacity, current density, and charge density were found to stay consistent, independent of the choice of solvent.

“…Numerous reports have already demonstrated the potential of PILs in applications including catalysis, 21,22 dye-sensitized solar cells, 23 electrochromic devices, 24,25 gas separation membranes, 26,27 antimicrobial surfaces, 28 sensors and actuators, 29,30 electrolyte-gated transistors, 31 fuel cells, 32 as well as devices for energy storage such as batteries or super-capacitors. [33][34][35][36] Most of these applications rely on PILs having enhanced ion conducting properties generally in the form of highly viscous liquids. Several strategies have been developed to yield mechanically stable PIL-based solid electrolytes.…”
