In situ formed self-healable quasi-solid hybrid electrolyte network coupled with eutectic mixture towards ultra-long cycle life lithium metal batteries

Rationally Designed Fluorinated Polycation Electrolytes for High-Rate, Dendrite-Free Lithium Metal Batteries

“…44,45 The absorption peak at 1351 cm −1 was indicative of the −SO 2 − stretching vibration within the MAIL structure. 46 The appearance of the above characteristic peaks in EFA proved that MAIL, PFS, PEGMA, and PEGDMA were successfully copolymerized into the polymer network.…”

“…The characteristic peak associated with C–O–C stretching was identified at the wavenumber of 1035 cm –1 . The absorption peaks observed at 1519 and 1492 cm –1 were assigned to the stretching vibrations of the aromatic ring CC and the −CF stretching vibration in the PFS, respectively. , The absorption peak at 1351 cm –1 was indicative of the −SO 2 – stretching vibration within the MAIL structure . The appearance of the above characteristic peaks in EFA proved that MAIL, PFS, PEGMA, and PEGDMA were successfully copolymerized into the polymer network.…”

Temperature-Responsive Solvation of Deep Eutectic Electrolyte Enabling Mesocarbon Microbead Anode for High-Temperature Li-Ion Batteries

“…New concepts in electrolytes, such as solid electrolytes, − ionic liquids, , high-concentration electrolytes, , and deep eutectic electrolytes (DEEs), − are widely regarded as advanced electrolytes with high safety. DEEs possess promising potential for next-generation Li batteries serving in high-temperature environments thanks to their low cost, easy preparation, nonflammability, and nonvolatility. − DEEs are formulated by mixing two or more components through Lewis or Brønsted acid/base interactions.…”

Lithiophilic Nanowire Guided Li Deposition in Li Metal Batteries

“…[13,14] This results in excess electrolyte consumption, causing high overpotentials with low coulombic efficiencies during the charge/discharge process. [3,4,15] Several strategies have been proposed to overcome issues in Li-metal anodes such as modification of electrolytes to promote uniform Li deposition, using different salts and salt concentrations, [16][17][18] additives, [19,20] fluorinated solvents [21][22][23] and (quasi) solid state electrolytes [24,25] as well. Another strategy involves the formation of artificial SEI layers that can limit electrolyte consumption.…”
