“…As presented in Figure S22 in the Supporting Information, the deconvolution of the F 1s spin‐orbital singlet in pure PVDF‐HFP separator is located at 687.6 eV, corresponding to the CF bond. The CF bond shifts to a higher binding energy (688.1 eV) for the active oxide/polymer separator (Figure k), demonstrating the enhanced interaction between strong electron‐withdrawing groups of CF (PVDF‐HFP) and O (CuO), which is consistent with the results of DFT calculations.…”

“…The relatively strong signals of Cu and O in the wide-scan survey XPS spectrum reveal the existence of CuO on the surface of the PVDF/CuO separator ( Figure S21, Supporting Information). The CF bond shifts to a higher binding energy (688.1 eV) for the active oxide/polymer separator (Figure 4k), demonstrating the enhanced interaction between strong electron-withdrawing groups of CF (PVDF-HFP) and O (CuO), [57] which is consistent with the results of DFT calculations. The singlet peak located at 932.1 eV is assigned to Cu + from Cu 2 O, [55] which likely formed during the hydrothermal reaction.…”

Structural/compositional characteristics at the anode/electrolyte interface are of paramount importance for the practical performance of lithium ion batteries, including cyclic stability, rate capacity, and operational safety. The anode‐electrolyte interface with traditional separator technology is featured with inevitable phase discontinuity and fails to support the stable operation of lithium ion batteries based on large‐capacity anodes with structural change in charges/discharges, such as transition metal oxide anodes. In this work, an anode/electrolyte framework based on an oxide anode and an active‐oxide‐incorporated separator is proposed for the first time and investigated for lithium ion batteries. The architecture builds a robust anode‐separator interface in LIBs, shortens Li+ diffusion path, accelerates electron transport, and mitigates the volume change of the oxide anode in electrochemical reactions. Remarkably, 4 wt% CuO addition in the separator leads to a 17% enhancement in the overall capacity of a battery with a CuO anode. The battery delivers an unparalleled record reversible capacity of 637.2 mAh g−1 with a 99% capacity retention after 100 charge/discharge cycles at 0.5 C. The high performance are attributed to the robust anode‐separator interface, which gives rise to enhanced interaction between the oxide anode and the same‐oxide‐incorporated composite in the separator.

“…In recent years, there has been growing demand of polymer electrolytes (PEs) for superior applications such as batteries, fuel cells, solar cells, supercapacitors etc., because of numerous outstanding properties such as light weight, safety, easiness in processing, high compliance, better adherence to the electrodes and prospect of fabrication into thin film geometries . However, owing to the low ionic conductivity of solid polymer electrolytes (SPEs), they are hardy applied in large‐scale commercial electronic equipment . Fortuitously, gel polymer electrolytes (GPEs) have currently received significant attention due to their excellent advantages in terms of high ionic conductivity, excellent mechanical and chemical stability .…”

Nanocomposite gel polymer electrolytes (NCGPEs) comprising of the solution of zinc trifluoromethanesulfonate [Zn(OTf)2] in 1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIMTFSI) ionic liquid entrapped in poly(vinyl chloride)/poly(ethyl methacrylate) blend and dispersed with zirconia (ZrO2) nanofiller has been prepared via simple solution casting method. The free standing film of the composite gel polymer electrolyte system exhibited the maximum room temperature ionic conductivity of 3.63 × 10−4 Scm−1 at 3 wt% nanofiller concentration with the accomplishment of highest zinc ion transference number of 0.66. The interaction and complexation among various constituents of the resultant NCGPEs has been confirmed from X‐ray diffraction (XRD) and Attenuated total reflection‐Fourier transform infrared (ATR‐FTIR) spectroscopic studies. Differential scanning calorimetry (DSC) and thermogravimetric (TG) analyses further corroborates the improved thermal behavior of ZrO2 added gel polymer electrolytes as compared with that of filler‐free gel electrolytes. The porous morphology of the thin films was observed by scanning electron microscopy (SEM) whereas the electrochemical properties of the NCGPEs were studied utilizing linear sweep voltammetry (LSV) and cyclic voltammetry (CV).

A gel material that can be applied to industry needs to fulfill two requirements: excellent mechanical properties and high temperature resistance. Previous research developed a hydrogel enhanced by sub‐5 nm particles, with excellent mechanical properties. While its application in the open environment is still limited by the volatilization of inner moisture, in this research, a non‐volatile gel (NV gel) enhanced by 5‐nm spherulites is manufactured. The NV gel remains stable after staying at 90 °C for 24 h. Meanwhile, being enhanced by sub‐5 nm nanospherulites, the NV gel shows good mechanical properties: with 200 ppm nanoparticle content, the tensile strength reaches 814 kPa and the compressive stress is 173.41 MPa at a recoverable 99% strain. The high temperature resistance is characterized by thermogravimetric analysis (TGA) and mechanical testing after thermal treatment. Transmission electron microscopy, scanning electron microscopy, Fourier transform infrared spectroscopy, time of flight secondary ion mass spectrometry, and thermogravimetric analysis are used to evaluate the microstructure of NV gel. Possessing non‐volatile and good mechanical properties at the same time, this NV gel becomes very suitable for fulfilling the application requirement as an engineering material.
