“…The remarkable improvement in the cycle performance of SiO 2 /Al 2 O 3 (1:1)-coated PI membranes was probably due to the favorable interface characteristic as well as strong affinity of SiO 2 /Al 2 O 3 (1:1)-coated PI membranes and the liquid electrolyte. Besides, SiO 2 and Al 2 O 3 could capture the acidic electrolyte magazines and trace amounts water of electrolyte, and reduce the capacity attenuation of battery [24][25][26]. The presence of SiO 2 reduced the impedance interface, the existence of Al 2 O 3 increased the ionic conductivity.…”

“…Based on our previous optimization [28,29,[31][32][33], doping 10 wt.% nanoparticles yields the best performance. Therefore, a total content of 10 wt.% nanoparticles was considered in this paper.…”

“…In our previous reports, it has been found that nano-SiO 2 is effective for the ionic conductivity improvement of GPEs [28][29][30][31][32][33], but the thermal stability of the matrix doped with nano-SiO 2 is not as good as those doped with other nanoparticles such as nano-Al 2 O 3 [34]. Considering the significant difference in chemical composition between SiO 2 (MW=60) and ZrO 2 (MW=123), we proposed a new method in this work for the performance enforcement of GPE by co-doping nano-SiO 2 and nano-ZrO 2 .…”

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 .

“…Inorganic nanoparticles, on one hand, provide transportation paths for lithium ion due to their Lewis-acid property, contributing to the increased ionic conductivity. The involved GPEs include nano-SiO 2 doped poly(butyl methacrylate-styrene) GPE [26] , poly (methyl methacrylate-acrylonitrile-vinyl acetate) (P(MMA-AN-VAc)) [ 35 ] and poly(methyl 4 methacrylate-co-butyl acrylate) [ 36 ] based GPEs, and nano-Al 2 O 3 doped poly(methyl methacrylate-vinyl acetate)-co-poly(ethylene glycol) diacrylate [ 37 ] , poly(ethylene oxide)-poly(vinylidene fluoride-hexafluoropropylene) [ 38 ] and poly(acrylonitrile-co-methyl methacrylate) [39] based GPEs. Among the inorganic nanoparticles that have been reported in GPEs, nano-Al 2 O 3 and nano-SiO 2 are believed to be most effective for the performance improvement of GPEs [33,34] .…”

In this article, we report a novel gel polymer electrolyte (GPE) for lithium ion battery, which is prepared by using poly(methyl methacrylate-acrylonitrile-ethyl acrylate) (P(MMA-AN-EA)) as polymer matrix and doping nano-SiO 2 and nano-Al 2 O 3 simultaneously.The influences of the ratio of two nanoparticles on the pore structure, electrolyte uptake and thermal stability of the resulting membrane and the ionic conductivity and electrochemical stability of the corresponding GPE are understood by scanning electron microscopy, mechanical strength, thermogravimetry, electrochemical impedance spectroscopy, linear sweep voltammetry and cyclic voltammetry. Particularly, the performance of the developed GPE for its application in lithium ion battery is evaluated in Li/LiNi 0.5 Mn 1.5 O 4 half cell by charge/discharge test. It is found that there exists a synergistic effect between nano-SiO 2 and 2 nano-Al 2 O 3 . The performances of the resulting membrane and the corresponding GPE are effectively improved by using nano-SiO 2 and nano-Al 2 O 3 simultaneously than individually.Co-doping 5 wt.% nano-SiO 2 and 5 wt.% nano-Al 2 O 3 provides the membrane with a higher thermally decomposed temperature of 325 o C and a better electrolyte uptake of 198.1%, the corresponding GPE with an increased ionic conductivity of 2.2×10 -3 S.cm -1 at room temperature and an enhanced oxidative stability up to 5.5 V (vs. Li/Li + ), and the LiNi 0.5 Mn 1.5 O 4 cathode with an improved rate capability of 104.2 mAh.g -1 at 2 C and an improved capacity retention of 94.8% after 100 cycles. These improved performances result from the combining advantages of both nano-SiO 2 and nano-Al 2 O 3 , in which the former contributes to the improved ionic conductivity caused by stronger Lewis-acid property, while the latte to the better thermal and structural stability by its stiffness characterization.
