Nanofibrous solid polymer electrolytes were prepared using the electrospinning method. These nanofibres were constructed from poly(ethylene oxide), lithium perchlorate and ethylene carbonate, which were incorporated with multi‐walled carbon nanotube (MWCNT) and graphene oxide (GO). The morphological properties of the as‐prepared electrolytes and the interaction between the components of the composites were characterized using scanning electron microscopy and Fourier transform infrared spectroscopy, respectively. X‐ray spectra and differential scanning calorimetry indicated an increase in amorphous regions of the nanofibrous electrolytes on addition of the fillers. However, the crystalline regions were increased on incorporation of fillers into polymeric film electrolytes. The conductivity values of the nanofibrous electrolytes reached 0.048 and 0.057 mS cm−1 when 0.35 wt% MWCNT and 0.21 wt % GO were introduced into the nanofibrous structures, respectively. The capacity and cycling stability of the nanofibrous electrolytes were improved by incorporation of MWCNT filler. Furthermore, stress and elongation modulus were improved at low MWCNT and GO filler contents. Results revealed that the nanofibrous structures could be promising candidates as solvent‐free electrolytes applicable in lithium ion batteries. © 2019 Society of Chemical Industry

“…To facilitate Li + transportation in solid polymer electrolytes, one efficient strategy is adding inorganic fillers such as zero‐dimensional SiO 2 , TiO 2 , Al 2 O 3 , 1D Li 0.33 La 0.557 TiO 3 nanowires, and 2D graphene oxide and MXene into the polymer matrix, producing inorganic/polymer electrolytes . Such inorganic fillers usually enable to plasticize polymers, reducing polymer crystallinity and enhancing the molecular chain motion of the polymers .…”

“…Particularly, the fillers with abundant chemical functional groups (such as OH) can facilely combine with the ionic species via Lewis acid–base interactions, acquiring highly dissociated lithium salts, thereby greatly promoting the Li + transportation at inorganic filler/polymer matrix interfaces . Therefore, high surface area fillers with abundant functional groups such as graphene oxide, vermiculite sheets, and MXene‐Ti 3 C 2 are beneficial to the formation of highly conductive polymer electrolytes (≈10 −4 S cm −1 ) . For instance, in the case of adding emerging MXene‐Ti 3 C 2 in PEO electrolyte, the ionic conductivity can be improved to 7.0 × 10 −10 S cm −1 , five times than that of the pure PEO electrolyte (1.4 × 10 −10 S cm −1 ) .…”

Although solid polymer electrolytes have some intrinsic advantages in synthesis and film processing compared with inorganic solid electrolytes, low ionic conductivities and mechanical moduli hamper their practical applications in lithium‐based batteries. Here, an efficient strategy is developed to produce a unique solid polymer electrolyte containing MXene‐based mesoporous silica nanosheets with a sandwich structure, which are fabricated via controllable hydrolysis of tetraethyl orthosilicate around the surface of MXene‐Ti3C2 under the direction of cationic surfactants. Such unique nanosheets not only exhibit individual, thin, and insulated features, but also possess abundant functional groups in mesopores and on the surface, which are favorable for the formation of Lewis acid–base interactions with anions in polymer electrolytes such as poly(propylene oxide) elastomer, enabling the fast Li+ transportation at the mesoporous nanosheets/polymer interfaces. As a consequence, a solid polymer electrolyte with high ionic conductivity of 4.6 × 10−4 S cm−1, high Young's modulus of 10.5 MPa, and long‐term electrochemical stability is achieved.

Lithium iron orthosilicate (LFS) cathode can be prepared via the polyol-assisted ball milling method with the incorporation of carbon derived from eggshell membrane (ESM) for improving inherent poor electronic conduction. The powder X-ray diffraction (XRD) pattern confirmed the diffraction peaks without any presence of further impure phase. Overall, 9 wt.% of carbon was loaded on the LFS, which was identified using thermogravimetric analysis. The nature of carbon was described using parameters such as monolayer, and average surface area was 53.5 and 24 m 2 g −1 with the aid of Langmuir and Brunauer-Emmett-Teller (BET) surface area respectively. The binding energy was observed at 285.66 eV for C-N owing to the nitrogen content in eggshell membrane, which provides more charge carriers for conduction. Transmission electron microscopy (TEM) images clearly show the carbon coating on the LFS, the porous nature of carbon, and the atom arrangements. From the cyclic voltammetry (CV) curve, the ratio of the anodic to the cathodic peak current was calculated as 1.03, which reveals that the materials possess good reversibility. Due to the reversibility of the redox mechanism, the material exhibits discharge specific capacity of 194 mAh g −1 for the first cycle, with capacity retention and an average coulombic efficiency of 94.7% and 98.5% up to 50 cycles.Energies 2020, 13, 786 2 of 13 iron silicate (Li 2 FeSiO 4 ) arrived in 2005 with the theoretical capacity twice the time of LiFePO 4 . It is also a safer and environmentally benign cathode material for energy storage applications [17]. Physical and electrochemical factors such as structural imperfection, ion diffusion, and low electronic conduction inhibit the utilization of theoretical capacity [18]. The inherent poor electronic conduction and ionic diffusion must be resolved by adopting some approaches such as particle size reduction [19], metal doping [20], and carbon coating on the surface of LFS [21]. The reduced particle size of LFS paved a way to shorten the Li + diffusion path. Hence, nanosized materials are still emerging in Li-ion batteries [22]. Cation doping is an effective strategy for widening the Li + diffusion channel and increases the output voltage of LFS-based Li-ion batteries [23]. Carbon coating is another effective approach to improve the electronic conductivity of cathodes made from Li 2 FeSiO 4 . Not only does it display excellent conduction behavior, carbon established an ideal matrix for cathode LFS which is due to the high dispersal over the surface. Besides, carbon coating prevents the decomposition of the electrolyte and integrates the particles within the volume. In this LFS, different carbon sources have been used to enhance the conductivity of LFS [24]. In the sol-gel method, sorbitanlaurat was used as carbon source by Qu et al. [25] and obtained the specific discharge capacity of 187 mAh g −1 at 0.1 C. Yen et al. [26] reveals that carbon derived from L-ascorbic acid on LFS exhibits the capacity of 137 mAh g −1 at slow rate (C/16). The biolo...
