“…This is not the characteristic feature of polymeric ionogels, since they exhibit signicantly lower ionic conductivity than their parent ILs. 12 On the other hand, supramolecular ionogels possess certain disadvantages which are mainly related to their inferior mechanical strength and low(er) temperature range of their quasi-solid state with the sol-gel transition temperature being oen below 100 C. However, recent investigations reported on supramolecular ionogels with an enhanced mechanical strength and thermal stability. [13][14][15][16] Such results are promising and encourage further research in the direction for nding new LMWGs, which would efficiently gel ILs producing highly conductive, however mechanically and thermally stable supramolecular ionogels.…”

“…97 The four kinds of redox-active poly(ionic liquid)s were synthesized from poly(diallyldimethylammonium) (PDADMA) type poly(ionic liquid), which is a well-known commercially available poly(ionic liquid) already applied as a polymeric electrolyte for lithium batteries due to its low cost, non-corrosive nature, and safety. 98,99 As can be seen in Figure 5A, PDADMA was used as a mother poly(ionic liquid) and incorporated with AQ, TEMPO, and methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (TFSI) by anion exchange reactions, resulting in their homopolymer and copolymer forms. In addition, the ratio of redox-active groups and TFSI was controlled in the copolymers.…”

Recently, one of the most important scientific issues for a better future life for humanity is achieving the ability to intelligently harvest, store, and utilize energy with good efficiency because we are facing critical environmental pollution and exhaustion of energy resources. Moreover, dramatic developments in advanced electronics, such as portable and wearable devices and electric vehicles, are being realized. Therefore, energy storage systems (ESSs) are very important for the operation of these advanced electronics. Among the energy storage materials, redox-active polymers are very attractive for ESSs because they have outstanding advantages compared with metal-based energy storage materials. For this reason, redox-active polymers are currently attracting much attention. In this review, we classify the redox-active organic groups of redoxactive polymers. In addition, the latest advances in redox-active polymers and their promising application potential for ESSs are discussed with a specific focus on precise molecular designs, nanoarchitectonics, and other new approaches.

“…Previous studies on the influence of the PIL scaffold on Li + mobility have drawn some different conclusions. [32][33][34][35] For instance, Schönhoff et al [35] demonstrated that a positively charged polymer can selectively interact with anions based on the diffusion coefficient for each ionic species. Tiemblo et al proposed that the presence of polyelectrolyte induces the formation of Li-poor and Li-rich domains within the ionogel, enabling fast Li + transport through anion exchange in the Li-rich domain.…”

Monolithic ionogel electrolyte membranes (IGEMs) based on gelling scaffolds and ionic liquids have aroused intensive interest because of their broad processing compatibility, nonflammability, and favorable thermal and electrochemical features. However, the absence of functional scaffolds that concurrently enable high mechanical strength and Li+ transportability of IGEMs constrains the battery power and safety. Herein, a task‐specific IGEM monolith featuring high Li+ conductivity and outstanding thermal stability is demonstrated, whereby electrospun positively charged poly(ionic liquid) nanofibers serve as a thermotolerant scaffold for the IGEM. Regulating the Li+ environment in the IGEM enables the shift from the sluggish vehicular to fast structural Li‐ion transport mode. With the unique IGEM, the solid‐state Li||LiFePO4 cells achieve improved rate capability and good cyclability in a wide temperature range from 0 to 90 °C. Furthermore, practical solid‐state Li||LiFePO4 pouch cells with a cathode capacity of ≈2 mAh cm−2 have also been demonstrated.
