“…Silver ions and silver-based compounds are known bactericides and have geared research interests towards nanoparticles as antibacterial agents (Crabtree et al, 2003;Furno et al, 2004;El-Shanshoury et al, 2011;Abdeen et al, 2014;Kamel et al, 2016;Masoud et al, 2018;Ibrahim et al, 2019;Abdallah et al, 2020). Several studies proposed that silver nanoparticles show efficient antibacterial activity due to the large surface area that comes in contact with the microbial cells and thus, includes a higher percentage of interaction than larger particles of the identical parent material (Mulvaney et al, 1996;Morones et al, 2005;Pal et al, 2007).…”

“…On the other hand, the ether oxygens on the PEO polymer chains and counter anions of the lithium salts are Lewis bases. Therefore, the filler particles weaken the interaction between the polymer chains and enhance the lithium salt dissociations by attraction of the polymer chains and the counter anions of the lithium salts, respectively 15‐21 …”

Electrospun core‐shell nanofibers based on polyethylene oxide reinforced by multiwalled carbon nanotube and silicon dioxide nanofillers: A novel and effective solvent‐free electrolyte for lithium ion batteries

Summary Insertion of conductive fillers into solvent‐free polymer electrolytes enhances electrochemical behavior of the electrolyte membranes leading to higher ionic conductivity, lower capacity fading, and so on. Although, the presence of the conductive fillers in the polymer matrixes increases the risk of electrical shorting, herein, polyethylene oxide (PEO)‐based core‐shell nanofibers were prepared via a simple electrospinning method. In the core‐shell electrospun fibers, ethylene carbonate (EC) and lithium perchlorate (LiClO4) were used as a plasticizer and as a lithium salt, respectively. The core component was enwrapped by the PEO/EC/LiClO4 shell part incorporated with SiO2 nanoparticles. Various properties of the fabricated membranes were evaluated by changing the ratio of multiwall carbon nanotubes (MWCNTs) in the core part of the nanofibers. The morphology and core‐shell structure of the electrospun fibers were studied by FESEM and TEM images. According to FTIR and XRD results, addition of the EC plasticizer and the fillers into the as‐spun fibers increased the fraction of free ions and the amorphous regions. From electrochemical impedance spectroscopy studies, the ionic conductivity enhanced by insertion of the plasticizer molecules and the filler particles into the core‐shell structures. The highest ionic conductivities of 0.09 and 0.21 mS.cm−1 were obtained for the free‐filler and the filler‐loaded nanofibrous membranes, respectively. The prepared mats obeyed the Arrhenius behavior ( R2~1). Dielectric studies confirmed the obtained data from the ionic conductivities. Furthermore, the capacity residual was enhanced from 69% to 85% by incorporation of the MWCNTs filler into the core component of the electrospun nanofibers. The presented results may facilitate development of versatile nanofibrous membranes embedded with the conductive fillers as solvent‐free electrolytes applicable in lithium‐ion batteries.

“…8,9 In recent years, several SPEs with high ionic conducting property based on poly (ethylene oxide) (PEO), poly (methyl methacrylate) (PMMA), polyacrylonitrile (PAN), and poly (vinylidene fluoridehexaflour propylene) (PVDF-HFP) had been reported. [10][11][12][13][14][15] Especially, because of their (the ether chains) strong interactions with lithium ions and the unique ionic conducting characteristics, much attention had been devoted to SPE based on PEO. [16][17][18] However, the properties of PEO-based SPEs studied at present were far from being able to meet the applicable requirement.…”

SUMMARY Solid polymer composite electrolyte (SPCE) with good safety, easy processability, and high ionic conductivity was a promising solution to achieve the development of advanced solid‐state lithium battery. Herein, through electrospinning and subsequent calcination, the Li0.33La0.557TiO3 nanowires (LLTO‐NWs) with high ionic conductivity were synthesized. They were utilized to prepare polymer composite electrolytes which were composed of poly (ethylene oxide) (PEO), poly (propylene carbonate) (PPC), lithium bis (fluorosulfonyl)imide (LiTFSI), and LLTO‐NWs. Their structures, thermal properties, ionic conductivities, ion transference number, electrochemical stability window, as well as their compatibility with lithium metal, were studied. The results displayed that the maximum ionic conductivities of SPCE containing 8 wt.% LLTO‐NWs were 5.66 × 10−5 S cm−1 and 4.72 × 10−4 S cm−1 at room temperature and 60°C, respectively. The solid‐state LiFePO4/Li cells assembled with this novel SPCE exhibited an initial reversible discharge capacity of 135 mAh g−1 and good cycling stability at a charge/discharge current density of 0.5 C at 60°C.
