Summary: With the increasing demand for electrochemical energy storage, commercial lithium-ion and metal battery systems have been developed. The separator, an essential component of batteries, plays a crucial role in determining their electrochemical performance. However, conventional polymer separators have limitations that hinder the development of electric vehicle power batteries. Advanced graphene-based materials have emerged as a solution to these challenges. Incorporating advanced graphene-based materials into the separator of batteries can overcome these issues and enhance their capacity, stability, and safety. This review provides an overview of the preparation and applications of graphene-based materials in different types of batteries, and outlines future research directions in this field.

Summary: Efficient thermal coupling between graphene and polymer matrix is crucial for achieving high thermal conductivity polymer-graphene nanocomposites. In this study, edge-functionalization of graphene nanoplatelets is shown to enable a larger enhancement of thermal conductivity compared to basal plane functionalization. The anisotropy of thermal transport in graphene and the weak van der Waals bonding between layers contribute to the beneficial effect of edge bonding. This study provides a novel pathway for achieving high thermal conductivity polymer nanocomposites.

Summary: High-performance PVDF separators have been successfully fabricated for lithium-ion batteries (LIBs) using a crystallization template in PVDF/PBSU blends. The co-continuous structures of crystalline and amorphous phases in PVDF contribute to superior mechanical performance and heat resistance. The removal of PBSU results in the formation of 3D interpenetrated nanochannels, enhancing the diffusion channels and improving the safety of LIBs. The optimal PVDF-30 specimen exhibits higher discharge capacity, higher coulombic efficiency, and enhanced cycle stability compared to the reference material.

Summary: Through hydrothermal assembly and high-temperature carbonization, we designed a novel NiCo2O4@nitrogendoped carbon nanotube@3D graphene (NCO@CT@3DG) aerogel to overcome the issues of large volume expansion and poor electrical conductivity in redox-based electrode materials. The NCO@CT@3DG aerogel exhibited excellent electrochemical properties as an anode material for lithium-ion batteries, with high capacity, superior cycle and rate performance. The outstanding properties are attributed to the synergistic effect of each component and the unique graphene aerogel hybrid structure. This study demonstrates the great potential of 3DG aerogel hybrid structure in improving electrochemical properties of active materials with high volume expansion and poor conductivity.

Summary: This work proposes a facile covalent self-assemble strategy to prepare the ZrN@rGO composite for enhanced LIB. The results show that a strong Zr-C covalent bond is formed between ZrN and rGO, and electron transfer promotes charge density at the ZrN@rGO heterointerface. The volume change of ZrN can be effectively alleviated by coupling with rGO, leading to a high specific capacity in the lithium-ion battery.

Summary: Extensive research has revealed that oxygen evolution reaction (OER) in alkaline conditions involves dynamic surface restructuring. The development and design of sulfide/oxide pre-catalysts can reasonably adjust the composition and structure after surface reconstruction, which is crucial for OER. This study utilized a simple two-step hydrothermal method to achieve in situ S leaching and doping, inducing the composition change and structure reconstruction of CoFe oxides. The transformed FeOOH and CoOOH exhibited excellent OER activity and could be easily mass-produced using low-cost iron based materials and simple methods.

Summary: Zero-dimensional organic-inorganic metal halides (OMHs) are gaining attention in the fabrication of light-emitting diodes due to their broad emission band and high photoluminescence quantum yield. This work synthesized a zero-dimensional organic tetraphenylphosphonium bismuth chloride (TBC) that showed efficient blue light emission, with the emission mechanism attributed to the transition of Bi3+ ions. White light-emitting diodes (WLEDs) were fabricated using TBC, along with green-emitting and red-emitting single crystals, achieving single-component white emissions. These findings demonstrate the different emission mechanism of ns2 ions-based OMHs and highlight the potential of bismuth-based OMHs in WLEDs applications.

Summary: The revolutionary design concept of high-entropy alloys has brought new opportunities and challenges to the development of advanced metal materials. In this work, AlCrCuFe2NiTix high-entropy flux cored wires were prepared by combining the design idea of a high-entropy alloy with the characteristics of flux cored wire. AlCr-CuFe2NiTix high-entropy surfacing alloys were prepared using gas metal arc welding technology. The wear properties of the alloys were analyzed, and the phase composition, microstructure, strengthening mechanism, and wear mechanism were discussed. The results show that the alloys exhibit a dendritic microstructure with BCC/B2 + FCC phases. Increasing Ti content leads to the precipitation of Laves phase. The alloys show improved microhardness and wear resistance due to the precipitation of coherent B2 and Laves phases. However, excessive Ti addition results in the increase of Laves phase and reduced wear resistance of the alloys.

Summary: In this study, six bimetallic FeCo particles were synthesized via the hydrothermal method at different Fe:Co ratios. The Fe:Co ratio not only modulates the composition of the particles but also influences their structure and magnetic properties. The FeCo alloys showed a transformation from an Fe-based structure to a Co-based structure with increasing Co content. The Fe:Co ratio of 1:1 and 3:1 resulted in particles with the highest and lowest saturation magnetization, respectively.

Summary: We conducted a study on the formation of ultra-fine Y-Ti-Ta-O nano-oxides in Ta+B micro-alloyed 13CrWTi-ODS alloys using electron microscopy and first-principles calculations. The Y-Ti-Ta-O nano-oxides were found to be mainly Y2(Ti,Ta)2O7, with an average size of 7 nm and a number density of 6.8 x 1023 m-3. Excess boron was found to enhance the adhesion of some low-sigma grain boundaries but weaken the Fe/Y2Ti2O7 interface, while excess tantalum enhanced the Fe/Y2Ti2O7 interface but caused serious degradation of grain boundaries.

Summary: The structure and magnetism of cobalt ferrites after Mn2+-Tb3+ co-doping were studied. Co-doped samples exhibited cubic spinel structure and spherical shape of ferrite nanoparticles. The redistribution of Co2+ and Fe3+ ions between octahedral and tetrahedral sites was observed due to Mn2+-Tb3+ co-doping. The coercivity and magnetization saturation of co-doped samples were significantly improved, leading to a maximum energy product that is 190% higher than that of the un-doped sample.

Summary: Recently, there has been an increasing interest in developing ultra-fine nanostructured electrodes with extensive reaction areas to enhance the performance and low-temperature operation of solid oxide fuel cells. The use of a refined approach involving co-sputtering metal alloys and oxide targets has demonstrated the feasibility of nano-columnar structures in perovskite-based electrodes, expanding the temperature range of thin film electrodes. This study systematically examines the effects of chamber pressure control in the co-sputtering process and identifies the intricate relationship between sputtering pressure and film structure. By fine-tuning the columnar growth in the electrode, significant improvements in performance and thermo-mechanical properties were achieved, resulting in high-performance all-sputtered solid oxide fuel cells.
