In this work, we report a new method to enforce the comprehensive performances of gel polymer electrolyte (GPE) for lithium ion battery. Poly(methyl methacrylateacrylonitrile-vinyl acetate) [P(MMA-AN-VAc)] is synthesized as polymer matrix. The physical and electrochemical performances of the matrix and the corresponding GPEs, doped with nano-SiO 2 and nano-ZrO 2 particles individually or simultaneously, are investigated by scanning electron microscopy, thermogravimetry, electrochemical impedance spectroscopy, and charge/discharge test. It is found that the membrane co-doped with 5 wt.% nano-SiO 2 +5 wt.% nanoZrO 2 and the corresponding GPE combine the advantages of those doped individually with 10 wt.% nano-SiO 2 or 10 wt.% nano-ZrO 2 . Accordingly, the comprehensive performances of the membrane and the corresponding GPE, in terms of thermal stability, ionic conductivity, and electrochemical stability on the anode and cathode of lithium ion battery, is enforced by co-doping 5 wt.% nano-SiO 2 and 5 wt.% nano-ZrO 2 .

This paper reported on a new gel polymer electrolyte (GPE) based on polyethylene (PE) non-woven fabric supported poly(acrylonitrile-vinyl acetate) (P(ANVAc)/PE) membrane for lithium ion battery use. The preparation and performances of the P(AN-VAc)/PE membrane and its GPE based on 1 M LiPF 6 in dimethyl carbonate/diethylene carbonate/ethylene carbonate (1:1:1 in volume) were investigated with a comparison of the unsupported P(AN-VAc) membrane. It is found that the P(AN-VAc)/PE membrane shows better mechanical strength and pore structure for electrolyte uptake than the P(AN-VAc) membrane, and subsequently the GPE based on P(AN-VAc)/PE exhibits higher ionic conductivity and electrochemical stability on cathode than the GPE based on P(AN-VAc). With the support of the non-woven fabric, the ionic conductivity of the GPE at room temperature increases from 1.4 to 3.8 mS cm -1 , the oxidation decomposition potential of the GPE on a stainless steel is improved from 5.0 to 5.6 V (vs. Li/Li ? ). The mesocarbon microbeads (MCMB)/LiMn 2 O 4 battery using P(AN-VAc)/ PE as separator retains 94% of its initial discharge capacity after 100 cycles at C/2 rate, showing that the P(AN-VAc)/ PE membrane is a possible alternative to the expensive separator for current liquid lithium ion battery.

“…), and sufficient dimensional stability to serve as separators in batteries [2,3]. In order to meet the above requirements, porous polymer membranes as polymer matrices for polymer electrolytes have been extensively studied [4][5][6]. Up to now, several processing methods have been developed for porous membranes' preparation including solvent casting [7,8], phase inversion [9,10], and electrospinning [11].…”

A series of novel fibrous polymer electrolytes with high ionic conductivity based on electrospun poly (methyl methacrylate-co-2-acrylamido-2-methylpropanesulfonic acid lithium) (P(MMA-co-AMPSLi)) membranes were prepared and characterized. P(MMA-co-AMPSLi) was synthesized by free radical copolymerization of MMA and AMPS, followed by ion exchange of the H ? with Li ? . The fibrous polymer electrolytes were fabricated by immersing the electrospun P(MMA-co-AMPSLi) membranes into the liquid electrolyte. Fourier transform infrared spectroscopy and 1 H-nuclear magnetic resonance were used to characterize the structure of the copolymers. Thermogravimetric analysis was applied to investigate the thermal properties of the copolymers. Scanning electromicroscope was employed to observe the morphology of electrospun membranes before and after soaking the liquid electrolyte. AC impedance and linear sweep voltammetry were adopted to measure the electrochemical properties of the fibrous polymer electrolytes. The incorporation of the AMPSLi units effectively improved the electrospinnability of the copolymer, increased the dielectric constants of the electrospun membranes, and enhanced the dimensional stability by maintaining the pore structures even after the membranes absorbing large amounts of liquid electrolytes. As a result, the ionic conductivity of the polymer electrolytes increased with the increase in the molar ratio of AMPSLi units, and the highest ion conductivity was up to 4.12 9 10 -3 S cm -1 at room temperature. Meanwhile, the polymer electrolytes studied in this work exhibited a sufficient electrochemical stability (up to 5.0 V) that allows the safe operation in lithium-ion batteries.
