“…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. The ceramic fillers can promote electrochemical properties, but only by physical action without directly contributing to the lithium ion transport process.…”

In this paper, the single ionic conductor SiO 2 (Li ? ) was first synthesized from Tetraethylorthosilicate and c-(2,3-epoxypropoxy) propyltrimethoxysilane (KH560) by sol-gel hydrolysis and then neutralized by lithium hydroxide in methanol. The poly(vinylidene fluoride) based composite microporous gel polymer electrolytes (CMGPEs) doped with SiO 2 (Li ? ) was prepared by phase inversion method and the desirable CMGPEs was obtained after being activated in liquid electrolyte. The physicochemical properties of the CMGPEs were characterized by FT-IR, DSC, XRD, TG, stress-strain response and electrochemical measurements. It was found that with the addition of SiO 2 (Li ? ), the degree of crystallization of microporous polymer membrane was decreased while its porosity increased, which could promote the absorption and gelation of liquid electrolyte. In addition, due to vast amount of Li ? ions in the SiO 2 (Li ? ), it would promote ionic conductivity at room temperature for the CMGPEs. When the content of SiO 2 (Li ? ) reached 5 %wt, the ionic conductivity of the CMGPEs could reach 10 -2 S/cm order of magnitude at room temperature and the reciprocal temperature dependence of ionic conductivity of as-prepared CMGPEs follow arrhenius equation, in addition, its electrochemical stability window could reach 5.2 V.

“…The NCPEs show tremendous technological potential to develop flexible solid state polymeric batteries over the solid polymer electrolytes (SPEs). The main advantages of NCPEs are their mechanical properties, ease of fabrication of desirable shapes/sizes, and they are also important for improving the proper contact between electrode-electrolyte in polymeric batteries [1][2][3][4][5][6][7][8]. In the recent past, several PEO-based polymer electrolytes have been widely investigated because of their potential application in polymeric batteries.…”

Synthesis, characterization and polymeric battery studies of Na + ion conducting NanoComposite Polymer Electrolyte (NCPE) membranes: (1-x) [75PEO: 25NaPO 3 ]: x SiO 2 , where x = 0 -15 wt. (%), has been reported. NCPE membranes have been casted using a novel hot-press technique in place of the traditional solution cast method. The dispersal of SiO 2 in SPE host: (75PEO: 25NaPO 3 ), a conductivity enhancement of an order of magnitude achieved in NCPE film: [93 (75PEO: 25NaPO 3 ): 7 SiO 2 ]. This has been referred to as Optimum Conducting Composition (OCC). Material characterizations have been done with the help of XRD, SEM and DSC techniques. The ion transport behaviour in hot-pressed NCPEs has been discussed on the basis of experimental measurements on some basic ionic parameters viz. conductivity (σ), ionic mobility (µ), mobile ion concentration (n) and ionic transference number (t ion ). The temperature dependent conductivity studies have been done to compute the activation energy (E a ) values from the 'log σ -1/T' Arrhenius plots. The ion conducting solid state polymeric battery was fabricated and cell-potential discharge characteristics have been studied at different load conditions.

“…14,22 However, in fact, the role of ceramic fillers seems to be quite different from that of liquid plasticizers, which significantly change the dynamics of polymer chain and thus promote the segmental conductivity. 23,24 In contrast, the T g values of the PEO-based electrolyte systems were not noticeably changed by the addition of ceramic fillers, preserving the initial amorphous structures. Lewis acid-base type interactions between filler surface groups and cations/ anions appear to be responsible for conductivity enhancement (acidic > basic > neutral > weakly acidic).…”

The current solid polymer electrolytes suffer from poor conductivity, low mechanical and electrochemical stability toward the lithium electrodes. To improve the performance of solid polymer electrolytes, the addition of nanoparticle fillers to the polymer electrolyte is being extensively investigated. In this paper, a brief review on the state of art of solid fillers for lithium battery electrolytes is presented.
