“…The weight ratio of PLTB/PVDF-HFP/(EC/DMC) was 0.50/0.50/2.0 (w/w/w). The thickness of the solvent swollen PLTB@PVDF-HFP membrane was ∼75 m. The surface morphology, the ionic conductivity, the electrochemical stability and lithium ion transference number of the solvents swollen PLTB@PVDF-HFP membrane were reported in our previous works [26].…”

“…Moreover, it was reported that the cell using LiBOB-based electrolyte maintained stable performance at elevated temperature due to excellent thermal stability and absence of HF [20,21]. Recently we reported a novel kind of "main-chain" type polymeric lithium tartaric acid borate, which possessed a high thermal decomposition temperature at 330 • C. It was verified that the ethylene carbonate/dimethyl carbonate (EC/DMC) swollen polymeric lithium tartaric acid borate @ poly(vinylidene fluorideco-hexafluoropropylene (PLTB@PVDF-HFP) exhibited a superior ionic conductivity at room temperature ( = 0.50 mS cm −1 ) and significantly high lithium ion transference number (t Li+ = 0.91) [26]. In addition, the gel-like PLTB@PVDF-HFP electrolyte could play a positive role in preventing the generation of Li dendrite [25].…”

a b s t r a c tThe LiMn 2 O 4 based lithium batteries using commercially available electrolytes suffer from poor cycling performance at elevated temperatures (above 55• C). This is mainly caused by the Mn dissolution generated from HF thermally decomposed from the LiPF 6 salt at elevated temperatures. In this paper, a single-ion gel polymer electrolyte (polymeric lithium tartaric acid borate @ poly(vinylidene fluoride-cohexafluoropropylene) was explored for improving the cycling performance of the LiMn 2 O 4 based lithium battery at elevated temperatures owing to superior thermal stability and comparable ionic conductivity. It was manifested that the Li/LiMn 2 O 4 cells using this single-ion gel polymer electrolyte showed stable charge/discharge voltage profiles, preferable rate capability and excellent cycling performance both at room temperature and elevated temperature of 55• C. The dissolution of metallic Mn in this electrolyte is significantly suppressed than that of LiPF 6 electrolyte. These superior performances could endow this single-ion gel polymer electrolyte a promising alternative to the conventional liquid electrolyte system in the LiMn 2 O 4 battery at elevated temperatures.

“…Auf der Suche nach einem idealen Lithiumsalz als Alternative für LiPF 6 wurde in den letzten Jahrzehnten eine enorme Forschungsarbeit geleistet, um neue Lithiumsalze zu entwickeln, zu synthetisieren und zu charakterisieren . Dabei sind die am intensivsten erforschten Lithiumsalze für Lithium‐Batterien thermisch und chemisch beständige Lithiumborate (typischerweise Lithiumbis(oxalato)borat (LiBOB), Lithiumdifluoro(oxalato)borat (LiDFOB)) und Lithiumimide (typischerweise Lithiumbis(trifluormethansulfonyl)imid (LiTFSI), Lithiumbis(fluorsulfonyl)imid (LiFSI)).…”

Durch einfaches Mischen verschiedener Lithiumsalze im Elektrolyten werden Gemischtsalz‐Elektrolyte formuliert, um einen synergistischen Effekt zu bewirken. Auf dem Gebiet der Lithium‐Batterien der nächsten Generation wurden große Fortschritte mit Gemischtsalz‐Elektrolyten erzielt. In diesem Aufsatz wird die Entwicklung derartiger Gemischtsalz‐Elektrolyten näher ausgeführt. Die Ziele der Formulierung von Gemischtsalz‐Elektrolyten für Lithium‐Batterien werden zusammengefasst: Verbesserung der thermischen Stabilität (Sicherheit), Verhindern der Korrosion der Aluminiumfolie des Kathoden‐Stromkollektors, Steigerung der Leistung über einen breiten Temperaturbereich (oder bei niedrigen oder hohen Temperaturen), Bildung günstiger Grenzflächenschichten an beiden Elektroden, Schützen der Lithium‐Metall‐Anode, Erreichen einer hohen Ionenleitfähigkeit usw. Darüber hinaus diskutieren wir wesentliche Aspekte bei der Formulierung von Gemischtsalz‐Elektrolyten für Lithium‐Batterien.

“…TGA showed decomposition temperatures of PLTB, PLPB, and PLDB were higher than 240 °C, beneficial to safety performances of battery. Based on “rigid–flexible coupling,” PLTB/PVDF‐HFP‐based gel polymer electrolytes were prepared by doctor‐blading and soaking process in PC or EC/DMC . Among them, PC swollen PLTB/PVDF‐HFP electrolyte possessed high Li + transference number of 0.93, which was much higher than LiBOB‐based electrolytes (<0.6) .…”

Polymer electrolytes have aroused wide interest in lithium batteries, but their comprehensive performances (including ionic conductivity, electrochemical window, and mechanical strength) need to be enhanced for high‐energy lithium batteries. A rigid–flexible coupling strategy is proposed to enhance the comprehensive performances of polymer electrolytes. To date, “rigid–flexible coupling” has been widely applied in gel and solid polymer electrolytes. For many kinds of polymer electrolytes, their ionic conductivity, electrochemical window, interfacial stability, and mechanical properties are significantly improved by “rigid–flexible coupling,” breaking their inherent application barriers in high‐energy lithium battery. Herein, recent key progress in rigid–flexible coupling polymer electrolytes is reviewed in terms of their design concepts, chemical‐physical properties, electrochemical performances, and battery properties. This overview also conducts a perspective for rigid–flexible coupling polymer electrolytes. It is hoped that fresh and established researchers can obtain a clear perspective of “rigid–flexible coupling” and this mini review can also throw light on the exploration of high‐energy polymer lithium batteries.
