Special Issue Information

Dear Colleagues,

Rechargeable batteries offer promising solutions to the energy-shortage issue. Lithium-ion batteries (LIBs) are among the most widely investigated systems; however, cost and safety concerns have limited their large-scale application. Although inorganic materials show ultra-high electrochemical performance, their further application is limited due to the shortage of resources, unfriendly environment, high price and other shortcomings. Polymers play an important role in batteries, such as separators, solid electrolytes, anode materials, cathode materials, etc.

The Special Issue of "Functional Polymer Composites Applied in Batteries" focuses on the application and research progress of polymers and their derivatives in various batteries, such as lithium/zinc/sodium/potassium-ion batteries and supercapacitors. In this Special Issue, original research articles and reviews are welcome, including but not limited to the abovementioned topics.

The polymeric material polyvinyl pyrrolidine/carboxymethyl cellulose (PVP/CMC) was mixed with different quantities of tungsten-trioxide nanoparticles (WO3 NPs). The samples were created using the casting method and Pulsed Laser Ablation (PLA). The manufactured samples were analyzed by utilizing various methods. The halo peak of the PVP/CMC was located at 19.65°, confirming its semi-crystalline nature, as shown in the XRD analysis. FT-IR spectra of pure PVP/CMC composite and PVP/CMC composite incorporated with various contents of WO3 obtained a shift in band locations and change in intensity. Optical band gap was calculated via UV–Vis spectra, which decreased when increasing the laser-ablation time. Thermogravimetric analyses (TGA) curves showed that samples’ thermal stability had improved. The frequency-dependent composite films were used to determine AC conductivity of the generated films. When increasing the content of tungsten-trioxide nanoparticles, both (ε′) and (ε′′) increased. The incorporation of tungsten trioxide enhanced the ionic conductivity of PVP/CMC/WO3 nano-composite to a maximum of 10−8 S/c. It is expected that these studies will have a significant impact on several utilizations, such as energy storage, polymer organic semiconductors, and polymer solar cells. Full article

Activated carbons (ACs) for supercapacitors were synthesized from Eucommia ulmoides Oliver (EUO) wood by H3PO4 with systemic activation processes. The target structure of ACs could be prepared by adjusting the technological parameters. As the H3PO4 concentration was 25%, the mass ratio of feedstocks to activator was 1:4, the activation time was 6 h, and the activation temperature was 400 °C, the obtained AC revealed a high specific surface area (2033.87 m2·g−1) and well-developed mesoporous (the rate of mesoporous was 96.4%) with the best economic feasibility. Besides, it possessed excellent electrochemical performance: the maximum specific capacitance reached up to 252 F·g−1, the charging and discharging period was 3098.2 s at 0.2 A·g−1, and the retention rate of specific capacitance reached 92.3% after 10,000 cycles. This low temperature and convenience technology provide a valuable reference for synthesizing the EUO-based ACs, making high-value utilization on the EUO branches, and owning a broad application prospect in supercapacitors.

The phenomenon of ordered self-assembly on solid substrates is a topic of interest in both fundamental surface science research and its applications in nanotechnology. The regulation and control of two-dimensional (2D) self-assembled supra-molecular structures on surfaces have been realized through applying external stimuli. By utilizing scanning tunneling microscopy (STM), researchers can investigate the detailed phase transition process of self-assembled monolayers (SAMs), providing insight into the interplay between intermolecular weak interactions and substrate–molecule interactions, which govern the formation of molecular self-assembly. This review will discuss the structural transition of self-assembly probed by STM in response to external stimuli and provide state-of-the-art methods such as tip-induced confinement for the alignment of SAM domains and selective chirality. Finally, we discuss the challenges and opportunities in the field of self-assembly and STM. Full article
