Effects of the porous structure on conductivity of nanocomposite polymer electrolyte for lithium ion batteries

Enhanced electrochemical and mechanical properties of P(VDF-HFP)-based composite polymer electrolytes with SiO2 nanowires

“…Among available power sources, much attention has been focused on lithium ion batteries employing polymer electrolytes instead of traditional liquid electrolyte solutions. This appears to be the most promising option because of intrinsically higher safety [1][2][3][4].…”

Novel Stable Gel Polymer Electrolyte: Toward a High Safety and Long Life Li–Air Battery

“…18,19 Meanwhile, to obtain the GPEs with improved ionic conductivity and interfacial properties at the lithium electrode, ceramic fillers, such as TiO 2 , SnO 2 , MgO, Al 2 O 3 and SiO 2 have been incorporated into host polymers. [20][21][22][23][24] Last but not least, owing to the existence of oxygenated radicals produced during the discharge process, some polymer compounds will be oxidized and unstable at the presence of Li 2 O 2 , such as P(VdF-HFP), poly(ethylene oxide) (PEO), polyacrylomtrile (PAN), 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 4 poly(vinyl chloride) (PVC), poly(vinylidene fluoride) (PVDF), and poly(vinylpyrrolidone) (PVP). [25][26][27] Thus, comprehensive work is required to address the stability issue of polymer-based electrolytes, and the exploration of stable GPE becomes significant for achieving Li-air battery with long operating life.…”

Study of P (VDF-HFP)/CNTs Composite Microporous Polymer Electrolyte for Li-Ion Batteries

“…MPE has higher ionic conductivity than solid polymer electrolyte and higher stability than liquid electrolyte, providing a solution to safety problems [2]. Many polymers have been reported to be used as MPEs, such as poly (vinylidene fluoride) (PVDF) [3] and polyvinyl chloride (PVC) [4]. The copolymer such as poly (vinylidene fluoride-hexafluoropylene) (P (VDF-HFP)) [5] perform well as the electrolyte materials.…”
