“…The results of this study confirmed that the increase in dopant molarity gives an effect on the increment of conductivity [11]. G. M. Hou, and co-worker, in 2016, showed a new polymer nanocomposite of nano-titanium dioxide/polyethylene oxide within situ synthesis hyper-branch poly (amine-ester) and its applications as a polymer electrolyte [12]. Al-Mokaram and his groups prepared Ppy/CH/TiO2 Nanocomposite Films [13].…”

Conducting polymer nanocomposites are the forthcoming materials for developing technologies, as they possess a combination of unique properties of their components. This study used the sol-gel technique to prepare and fabricate nanocomposite of polyaniline (PANI), with nanomaterial (TiO2), doped by tin (Sn+2) (PANI/Sn+2/TiO2). Novel nanocomposites were prepared in different ratios (5%, 10%, 15%, 20%, and 25%) of weight for the nanomaterial (Sn+2/TiO2) to the polymer (PANI). The prepared nanocomposites were characterized with several techniques including Fourier transform infrared (FT-IR) Spectrometer, Ultraviolet-visible (UV-vis.) spectroscopy, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), and Atomic Force Microscopy (AFM). This research has presented the role of nanomaterial and described the easy process of their homogenous distribution in the (PANI/Sn+2/TiO2) nanocomposites. The electrical conductivity of the prepared materials was examined and confirmed by electrical conductivity. The combination of Sn+2/TiO2 in the PANI matrix will be very valuable for the improvement of the physical and chemical properties of the polymer's conductivity.

“…This change had also been reported in similar studies. Hou et al [ 29 ] studied the crystallinity of hyper-branched poly(amine-ester) (HBPAE)/HBPAE-g-TiO 2 /PEO electrolyte by in situ synthesis of hyperbranched poly(urethane)-doped TiO 2 /PEO composite materials. The lowest crystallinity of the SPEs was acquired when the TiO 2 content reached 15 wt.%, while the value showed a slight improvement as the TiO 2 content further increased.…”

“…As a result, the improvement in electrochemical and mechanical performance is greatly restricted. A method called in situ synthesis was recently proposed to introduce ceramic particles through reactions occurring among different elements or compounds [ 5 , 19 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. The in situ synthesized ceramic particles possess clean surface and good dispersibility, excellent compatibility with the polymers, and high interface binding strength.…”

ZnO nanoparticles were successfully in situ synthesized in the form of PEO–COO− modified ZnO by a three-step method, based on which the solid polymer electrolytes (SPEs), based on polyethylene oxide (PEO) with excellent electrochemical performance, were prepared. The evolution of the electrochemical and mechanical performances of the SPEs with the ZnO content (0–5 wt.%) was investigated in detail. The mechanical property of the SPEs demonstrated a Λ-shaped change trend as increasing the ZnO content, so that the highest value was acquired at 3 wt.% ZnO. The SPE containing 3 wt.% ZnO had the most outstanding electrochemical performance, which was significantly better than that containing directly-added ZnO (2 wt.%). Compared with the latter, the ion conductivity of the former was improved by approximately 299.05% (1.255 × 10−3 S·cm−1 at 60 °C). The lithium-ion migration number was improved from 0.768 to 0.858. The electrochemical window was enhanced from 5.25 V to 5.50 V. When the coin cell was subject to the cycling (three cycles in turn from 0.1 C to 3 C, and subsequent fifty cycles at 1 C), the 68.73% specific capacity was retained (106.8 mAh·g−1). This investigation provides a feasible approach to prepare the SPEs with excellent service performance.

“…Generally, with increasing ceramic content, the ionic conductivity increases. The ionic conductivity reaches the maximum at the percolation threshold, such as 10 wt% LLZTO [ 75 ], 25 wt% LATP [ 92 ], 20 wt% LAGP [ 93 ], 5 wt% MnO 2 [ 90 ] and 7.5 wt% TiO 2 [ 94 ]. However, further increasing the ceramic content will block ion transmission and cause a decrease in ionic conductivity.…”

“…There are some criteria for the coating layer. First, the coating layer should have a similar surface energy to PEO for increasing the surface affinity between ceramic and polymer, greatly providing good compatibility and promoting Li + transportation at ceramic/polymer interfaces [ 94 , 170 ]. For example, PDA-coated LLZTO showed a lower contact angle of 76°, whereas pristine LLZTO showed a higher contact angle of 116° with PEO solution (Fig.…”

Composite solid electrolytes (CSEs) with poly(ethylene oxide) (PEO) have become fairly prevalent for fabricating high-performance solid-state lithium metal batteries due to their high Li+ solvating capability, flexible processability and low cost. However, unsatisfactory room-temperature ionic conductivity, weak interfacial compatibility and uncontrollable Li dendrite growth seriously hinder their progress. Enormous efforts have been devoted to combining PEO with ceramics either as fillers or major matrix with the rational design of two-phase architecture, spatial distribution and content, which is anticipated to hold the key to increasing ionic conductivity and resolving interfacial compatibility within CSEs and between CSEs/electrodes. Unfortunately, a comprehensive review exclusively discussing the design, preparation and application of PEO/ceramic-based CSEs is largely lacking, in spite of tremendous reviews dealing with a broad spectrum of polymers and ceramics. Consequently, this review targets recent advances in PEO/ceramic-based CSEs, starting with a brief introduction, followed by their ionic conduction mechanism, preparation methods, and then an emphasis on resolving ionic conductivity and interfacial compatibility. Afterward, their applications in solid-state lithium metal batteries with transition metal oxides and sulfur cathodes are summarized. Finally, a summary and outlook on existing challenges and future research directions are proposed.
