Effects of preparation conditions on porous polymer membranes by microwave assisted effervescent disintegrable reaction and their electrochemical properties

Polymer composites and blends for battery separators: State of the art, challenges and future trends

“…Thus, P(VDF-HFP) with effervescent disintegrant CPE i.e., the combination of the organic acid and base used in effervescent disintegrable reaction, showed a stable electrochemical window above 5 V [121]. The inclusion of MgO particles also enhanced the electrochemical stability of P(VDF-HFP) [130] and the addition of PZS into PEO extended the electrochemical stable window above 5 V [127].…”

Preparation and Characterization of Composite Microporous Gel Polymer Electrolytes Containing SiO2(Li+)

“…Special interest today is focused on composite gel polymer electrolyte systems having high ionic conductivity at ambient temperatures, since they may find unique applications, for example in rechargeable lithium batteries, separators, and fuel cells. Polyacrylonitrile (PAN) [1], poly(vinylidene fluoride) (PVDF) [2][3][4], poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) [5,6] and poly(methyl methacrylate) (PMMA) [7][8][9] are the most common host polymers used for preparing gel electrolytes. Ceramic fillers such as SiO 2 [10], Al 2 O 3 [11], TiO 2 [12] and BaTiO 3 [13] have been incorporated along with the host polymer in order to obtain composite polymer electrolytes with improved electrical and mechanical properties.…”

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

“…Gel polymer electrolytes (GPEs), wherein a polymer matrix such as poly(methylmethacrylate) (PMMA) [5][6][7], polyacrylonitrile (PAN) [8], poly(vinylidenefluoride) (PVDF) [9][10][11] or poly(vinylidene-fluoride-co-hexafluoropropylene) [P(VDF-HFP)] [12,13] is swollen in a liquid electrolyte becoming plasticized (i.e. a gelled polymer electrolyte), have attracted particular attention because they may provide lighter, safer and cheaper batteries with longer shelf life, leak proof construction and easy fabrication into desired shape and size [14].…”
