Flame-retardant composite gel polymer electrolyte with a dual acceleration conduction mechanism for lithium ion batteries

Sandwich-like solid composite electrolytes employed as bifunctional separators for safe lithium metal batteries with excellent cycling performance

“…6–8 In this context, on the one hand, lots of efforts for safe LMBs commonly focus on exploring fire-prevention systems by introducing a fire retardant into electrolytes, 9,10 modifying separators with inorganic particles, 11,12 designing thermoresponsive switch membranes and so on. 13–15 On the other hand, the studies aspiring to achieve long cycling properties pay close attention to fresh strategies of electrolyte/electrode interface engineering for dendrite-free lithium anodes, such as in situ formation of an artificial SEI film, 16–18 construction of three-dimensional lithium matrices, 19 preparation of high-strength composite separators as mechanical barriers, 20,21 and interfacial redistribution of ions across the separators or at the lithium metal surface. 22–24 Both categories of these methods provide diversified perspectives for the progress of high-performance LMBs, while most of them only achieve high fire resistance or good lithium dendrite inhibition alone.…”

Utilizing an Oxygen-Rich Interface by Hydroxyapatite to Regulate the Linear Diffusion for the Stable Solid-State Electrolytes

“…As shown in Figure 2b, the higher O density in PEO-HAP SPE makes the transport path smoother, so a lower migration energy barrier can be obtained. 40 The ionic conductivity of PEO-HAP SPE is shown in Figure 2c.…”

Three-Dimensional Printable, Highly Conductive Ionic Elastomers for High-Sensitivity Iontronics

“…used a lithium salt and a cross-linked copolymer network to prepare a solvent-free ICE that exhibited good mechanical properties in various sensing devices . However, challenges still exist, for example, the currently reported conductivity of ICEs should be further improved compared with gel-based ionic conductors to achieve some soft iontronics that required high conductivity …”

“…36 However, challenges still exist, for example, the currently reported conductivity of ICEs should be further improved compared with gel-based ionic conductors to achieve some soft iontronics that required high conductivity. 37 Here, we introduced a dynamically cross-linked, highly conductive, high-transparency, and stretchable solvent-free ICE. Lithium bis(trifluoromethane)sulfonimide (LiTFSI) was added to molten polyethylene glycol (PEG) to inhibit its crystallization at lower temperatures, even at −60 °C, to form a liquid polymer electrolyte (LPE).…”
