Summary: Amorphous zinc oxide incorporated with sulfur-doped carbon composite nanofiber (ZnO@S-CNF) was prepared through electrospinning and calcination for supercapacitor applications. Its self-supporting electrode achieved a high capacitance of 209 F/g at 1 A/g and sustained 158 F/g at 10 A/g. An asymmetric supercapacitor (ASC) assembled with ZnO@S-CNF as the positive electrode and carbon nanofiber as the negative electrode showed a specific energy of 11.2 Wh/kg at a specific power of 900 W/kg in the voltage range of 0-1.8 V. The enhanced performance was attributed to the increased surface area, micropore volume, and heteroatom content. This study provides a feasible approach for developing carbon composite electrodes with remarkable performance.

Summary: The symmetry and conductivity of perovskite oxides are greatly influenced by the size and valence states of cations. By substituting La3+ with Sr2+ and Mn3+ with Fe3+, the crystal symmetry and ionic-electronic conductivity of the perovskite can be improved. The use of carbon nano-onions as a negative electrode in an asymmetric hybrid supercapacitor greatly enhances its rate capability. Tuning the conductivities and using appropriate carbon-derived negative electrodes can pave the way for high-rate hybrid devices using different perovskites.

Summary: Graphene oxide (GO) has been widely studied for its improved properties compared to pure graphene, which make it suitable for electrochemical energy storage applications. The oxygenated groups on the surface of GO enhance its ionic mobility and density of states while maintaining the same specific area as pure graphene. Moreover, the porous morphology of the electrode enhances electrode-electrolyte interactions and increases the contact area. This study investigates the structural aspects of porous GO electrodes in different ionic liquids using atomistic molecular dynamics simulations and provides insights into the charging mechanisms in the presence of each electrolyte.

Summary: CO2 cycloaddition with epoxides is an important process for CO2 conversion to generate cyclic carbonates. However, the catalytic efficiency of porous organic polymers (POPs) for this process is typically low and requires severe conditions or prolonged reaction time. In this study, amine-impregnated porous organic polymers (HCP-TPP-Co-EDA-10 and HCP-TPP-Co-PEI-5) were developed to enhance the interaction with CO2 and improve catalytic efficiency. These catalysts exhibited strong binding affinity with CO2 and high catalytic yield under mild conditions. The turnover number (TON) and turnover frequency (TOF) achieved were among the highest reported so far. Additionally, the catalysts showed excellent recyclability and stability for CO2 conversion. The use of amines as chemisorption sites for CO2 provides a simple strategy for designing highly efficient functionalized hyper-cross-linked polymers (HCPs) for CO2 capture and chemical conversion.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
