polymerized ionic liquids (polyiLs) combine the unique properties of ionic liquids (iLs) with macromolecular polymers. But anion diffusivities in polyILs can be three orders of magnitude lower than that in ILs. Endeavors to improve ion transport in polyILs urgently need in-depth insights of ion transport in polyILs. As such in the work we compared ion transport in poly (1-butyl-3-vinylimidazoliumtetrafluoroborate) (poly ([BVIM]-[BF 4 ])) polyIL and 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM]-[BF 4 ]) IL. The diffusivities of ions in the polyIL and IL were measured and computed. According to the results of the molecular dynamics simulations performed, in the iL the coupling motion between an anion and the ions around determines the ion diffusivities, and the ion association lifetime gives the time scale of ion transport. But in the polyiL, the hopping of an anion among cages composed of cationic branch chains determines the diffusivity, and the associated anion transport time scale is the trap time, which is the time when an anion is caught inside a cage, not the ion association lifetime, as Mogurampelly et al. regarded. The calculation results of average displacements (ADs) of the polyIL chains show that, besides free volume fraction, average amplitudes of the oscillation of chains and chain translation speed lead to various diffusivities at various temperatures.

“…In addition to the SPE composites for battery systems, the polymeric ionic liquid (PIL) has been intensively studied in which they are synthesized from monomers of IL. Several ionic liquids are used for the polymerization, including: triethylmethylammonium bis(fluorosulfonyl)imide (N 1222 FSI), [ 142 ] EMImTFSI, or PYR14‐TFSI (EMIm: 1‐ethyl‐3‐methylimidazolium, and PYR14: 1‐butyl‐1‐methylpyrrolidinium), [ 143 ] 1‐vinyl‐3‐dodecylimidazolium bis(trifluoromethanesulfonyl) imide (VDIM‐TFSI), [ 144 ] N ‐Propyl‐ N‐ methylpyrrolidinium bis(fluorosulfonyl)imide (C3mpyrFSI), [ 145 ] 1‐vinyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide [ 56 ] and 1‐butyl‐1‐methylpyrrollidium bis(flouromethane sulfonyl) (BuMePyr‐TFSI).

Ionic liquids (ILs) have emerged as a novel class of chemical compounds for the development of advanced (multi)functional materials with outstanding potential in applications of several areas due to their unique properties and functionalities. The combination of ILs with polymers, in a composite, allows for developing smart materials, which synergistically combine the features of specific polymers and ILs. Moreover, ILs can be extensively modified by the incorporation of functional groups with specific properties into the cation, anion, or both. Thus, it is possible to tune the IL, the polymer, or both to obtain a broad spectrum of multifunctional composites and address the specific requirements of many applications. This work focusses on advanced materials and strategies concerning ILs and polymers for the development of smart IL/polymer‐based materials for applications including responsive and sensitive sensors, actuators, environment, batteries, fuel cells, and biomedical applications.

“…In particular, a Na//NaFePO 4 cell with P 111i4 FSI ionic liquid and NaFSI (sodium salt) as the electrolyte delivered a capacity of 85 mAh g −1 at C/2 at 50 °C, with a capacity retention of 95% after 100 cycles. Recently, this group further fabricated an ion gel membrane based on 50 wt.% poly(DADMA)-TFSI (a PIL that is already used in lithium batteries [306]) and 50 wt.% C3mpyrFSI, to which was added 14 mol% NaFSI salt plus 5 wt.% Al 2 O 3 nanoparticles to improve the mechanical properties [616]. 50 wt.% C3mpyrFSI was the optimum concentration, as a higher concentration, despite increasing the transference number, decreases the ionic conductivity.…”

Building Better Batteries in the Solid State: A Review

Most of the current commercialized lithium batteries employ liquid electrolytes, despite their vulnerability to battery fire hazards, because they avoid the formation of dendrites on the anode side, which is commonly encountered in solid-state batteries. In a review two years ago, we focused on the challenges and issues facing lithium metal for solid-state rechargeable batteries, pointed to the progress made in addressing this drawback, and concluded that a situation could be envisioned where solid-state batteries would again win over liquid batteries for different applications in the near future. However, an additional drawback of solid-state batteries is the lower ionic conductivity of the electrolyte. Therefore, extensive research efforts have been invested in the last few years to overcome this problem, the reward of which has been significant progress. It is the purpose of this review to report these recent works and the state of the art on solid electrolytes. In addition to solid electrolytes stricto sensu, there are other electrolytes that are mainly solids, but with some added liquid. In some cases, the amount of liquid added is only on the microliter scale; the addition of liquid is aimed at only improving the contact between a solid-state electrolyte and an electrode, for instance. In some other cases, the amount of liquid is larger, as in the case of gel polymers. It is also an acceptable solution if the amount of liquid is small enough to maintain the safety of the cell; such cases are also considered in this review. Different chemistries are examined, including not only Li-air, Li–O2, and Li–S, but also sodium-ion batteries, which are also subject to intensive research. The challenges toward commercialization are also considered.
