“…The Tg of the PEOx-PC copolymerbased SPE also decreased with the increase of the LiTFSI content (up to 30 wt.%). Vidal's group [81] found that the oligomer poly, PPO-PEO-PPO (POP: propylene oxide), based triblock polymer electrolyte showed a highly compliant to Arrhenius model, which is beneficial to the improvement on the ionic conductivity of the PEO-based SPE (Figs. 7(a) and 7(c)-7(f)).…”

Solid polymer electrolytes (SPEs) possess comprehensive advantages such as high flexibility, low interfacial resistance with the electrodes, excellent film-forming ability, and low price, however, their applications in solid-state batteries are mainly hindered by the insufficient ionic conductivity especially below the melting temperatures, etc. To improve the ion conduction capability and other properties, a variety of modification strategies have been exploited. In this review article, we scrutinize the structure characteristics and the ion transfer behaviors of the SPEs (and their composites) and then disclose the ion conduction mechanisms. The ion transport involves the ion hopping and the polymer segmental motion, and the improvement in the ionic conductivity is mainly attributed to the increase of the concentration and mobility of the charge carriers and the construction of fast-ion pathways. Furthermore, the recent advances on the modification strategies of the SPEs to enhance the ion conduction from copolymer structure design to lithium salt exploitation, additive engineering, and electrolyte micromorphology adjustion are summarized. This article intends to give a comprehensive, systemic, and profound understanding of the ion conduction and enhancement mechanisms of the SPEs for their viable applications in solid-state batteries with high safety and energy density.

“…This result indicates that the fraction of available Li + for conduction is the highest, and there are fewer interactions between dissociated Li + and EO units in the CPE-0.2LAP-IL-TFSI membrane. 42 The Li + transference number ( t + ) was calculated based on the chronoamperometric curves and the corresponding interfacial/bulk resistances before and after 10 mV DC polarization ( Fig. 2b , S7, and Table S2 † ).…”

“…(5) Last but not least, Vancaeyzeele et al [82] reported recently that the oligomer lithium salts synthesized from the Jeffamine-type PEAs were fully amorphous and highly conductive at high temperatures (e. g., 4.8 • 10 À 3 S cm À 1 at 100 °C). This would bring new opportunities for designing robust Jeffamine-based polysalts in the near future.…”

Rechargeable batteries are important building blocks for a sustainable and electrified society thanks to their strong capability of storing electrical energies under chemical forms. JEFFAMINE®, a series of polyetheramines (PEAs) currently produced by Huntsman Corporation, has been emerging as a promising candidate for accessing high-performance electrolytes and other cell components of rechargeable batteries. In this review, a brief history of the Jeffamine-type PEAs and the synthetic chemistry of the Jeffamine-based polymers are presented. The main applications of the Jeffamine-based polymers in rechargeable batteries are discussed and highlighted, including various kinds of polymer electrolytes, polymeric binders, redox-active materials, and interfacial layers stemming from the Jeffamine-type PEAs. Lastly, future directions on the rational design of Jeffamine-based materials are provided with the aim of improving the electrochemical performance of rechargeable batteries.
