“…It would result in the decrease in overall current density through the electrolyte due to the increase in the resistance to the flow of ions through the electrode–electrolyte interface. However, in the present case, the dispersed nanofiller SiO 2 having high surface area congregates on the surface of the electrode efficiently thus retarding the electrolyte–electrode reaction and successfully impeding the formation of SEI layer and hence passivation is suppressed …”

“…The enhancement in the electrochemical stability was due to the Lewis acid–base interaction between the nanofiller and CF 3 SO 3 − of the salt thereby impeding the decomposition of the zinc salt anion . Thus, the obtained satisfactory working voltage range of the nanocomposite gel film appears to be sufficient for its safety operation as a separator in zinc batteries at room temperature . The presence of non‐notched small background current signifies the absorption of trace impurities in the electrolyte by the nanopowders leading to a clean system with the higher decomposition voltage of ~5.07 V …”

“…Generally, the passivation of zinc electrode, due to its reactive nature with the PEs, leads to the formation of a non‐uniform solid electrolyte interface (SEI) passivation layer on the electrode materials. It would result in the decrease in overall current density through the electrolyte due to the increase in the resistance to the flow of ions through the electrode–electrolyte interface.…”

Zinc ion conducting nanocomposite gel polymer electrolytes (NCGPEs) comprising of poly(vinyl chloride) (PVC)/poly(ethyl methacrylate) (PEMA) blend, zinc triflate [Zn(OTf)2] salt, 1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIMTFSI) ionic liquid (IL) and fumed silica (SiO2) viz. [PVC/PEMA–Zn(OTf)2–EMIMTFSI–SiO2] exhibited the highest ionic conductivity value of 6.71 × 10−4 Scm−1 at room temperature. The ion–filler–polymer interactions and probable conformational changes observed in the structure of the gel composites due to the entrapment of IL and dispersion of nano‐sized SiO2 were confirmed from X‐ray diffraction (XRD) and Attenuated total reflection‐Fourier transform infrared (ATR‐FTIR) spectroscopy. Scanning electron microscopic (SEM) images of NCGPEs demonstrated uniform surface with abundant interconnected micropores. The cationic transport number of NCGPE samples has been found to be appreciably enhanced up to a maximum of 0.69 thus demonstrating a considerable improvement in Zn2+ ion conductivity. The NCGPE film possesses an electrochemical stability window up to 5.07 V (vs. Zn/Zn2+) and ensures feasible zinc stripping/plating in the redox process. The addition of SiO2 into the gel polymer electrolyte system has effectively reduced the glass‐transition temperature (Tg) of the NCGPE films and also accomplished improved thermal stability up to approximately 180 °C which were ascertained from Differential scanning calorimetry (DSC) and Thermogravimetric (TG) results. © 2019 Wiley Periodicals, Inc.

“…Because the electrolyte wetted at the interface remained in the holes during battery assembly and was not extruded by the steel sheet. The carbonyl side groups attributed to the structure of the acrylate unit played a strong role in the oxygen in the carbonate plasticizer 28 . Therefore, polyacrylate in PEA can contain liquid electrolyte to raise conductivity of PEA.…”

Solid polymer electrolyte is expected to be widely used in solid-state lithium batteries due to its good mechanical manufacturability and low cost. But the low ion conductivity, poor interface compatibility hindering the development of solid-state batteries. In this work, a rigid-flexible ultrathin ($13 μm) poly (ether-acrylate) (PEA) solid electrolyte membrane was prepared by controlling the mutual penetration of porous skeleton and electrolyte. For comparison, a thick PEA membrane ($30 μm) was also provided. We found that the thicker PEA membrane exhibits a porous structure and rough surface due to the physical shrinkage of polymer, while the ultrathin PEA shows more compact and flexible. Structural advantages give it higher tensile strength (114.7 MPa), doubled ionic conductance (218 mS), and higher lithium ion migration number from 0.81 to 0.93. Meanwhile, better interface contact was also achieved due to the smoother surface of ultrathin PEA, which promotes the uniform distribution of charges and uniform SEI film on the surface of lithium anode, thus inhibits the growth of lithium dendrites. Due to the improvement of basic physical properties and good interface contact, the assembled NCM622/PEA/ Li solid-state battery shows improved rate and cycle performances. Highperformance solid-state lithium batteries is expected to developed according to this ultrathin solid electrolyte membrane.

“…After drying at 75℃ for 2 days, an electrochemical window of 4.8V was obtained.With the decrease of electrolyte in the membrane, the ionic conductivity of the membrane decreased from 0.947 mS/cm to 0.150 mS/cm. (Table S1) The carbonyl side groups attributed to the structure of the acrylate unit play a strong role in the oxygen in the carbonate plasticizer [3] . Therefore, ETPTA can contain a large amount of liquid electrolyte, resulting in a very high conductivity of the gel.…”
