Summary: A simplistic nitrogen-doped hierarchically porous carbon material (HPC-A) was developed and hot-pressed on a carbon cloth (CC) substrate to fabricate capacitive bioanodes (HPC-A-CC) for enhanced electricity generation and storage in microbial fuel cells (MFCs). The HPC-A-CC anode exhibited higher power density, total charge, electrochemical activity, and capacitive behavior compared to the plain CC anode, and the HPC-A-CC biofilm showed higher cell viability and a more uniform spatial distribution.

Summary: MFC anodic denitrification combined with solid-phase denitrification was achieved by adding slow-release carbon source fillers (CPSP) to the anolyte. The MFC experimental group with CPSP showed a slightly longer start-up period but exhibited higher maximum output voltage and power density compared to the control group. CPSP improved the affinity and tolerance of MFC to nitrate, alleviated electron competition, and enhanced coulombic efficiency.

Summary: This review summarizes the progress in carbon-based materials for oxygen reduction reaction (ORR) catalysts and their utilization in microbial fuel cells (MFCs). Incorporating transition metals and heteroatoms into carbon can enhance the ORR activity and power generation in MFCs. Nitrogen-doped carbons have abundant active sites and superior conductivity, stability, and catalytic activity. Carbon-based catalysts and biomass-derived carbons show potential to replace expensive Pt catalysts for ORR.

Summary: A photocathode-microbial electrochemical coupling system (PC-MFC) using black phosphorus-doped titanium dioxide nanobelt (BP/TB) as a photocatalyst was constructed to degrade hydroxychloroquine (HCQ, used to treat COVID-19). The degradation efficiency of HCQ (100 mg/L) in the coupling system reached 73.7% within 8 hours, higher than photocatalysis (69.5%), MFC (25.6%), and adsorption (9.6%). The PC-MFC achieved complete degradation of HCQ (100 mg/L) within 96 hours, significantly higher than the MFC (51.1%).

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: An efficient phase inversion-impregnation approach is developed to fabricate BaO-decorated Ni8 mol% YSZ anode-supported tubular solid oxide fuel cells (SOFCs) with anti-coking properties. BaO nanoislands are successfully introduced inside the Ni-YSZ anode, leading to higher peak power densities and improved stability in methane fuel. Density functional theory calculations suggest that the loading of BaO nanoislands facilitates carbon elimination by capturing and dissociating H2O molecules to generate OH.

Summary: Li-CO2 batteries, which utilize CO2 and have a high energy density, are hindered in practical applications due to slow kinetics and safety hazards. This study introduces a stable and highly conductive ceramic-based solid electrolyte and a metal-organic framework catalyst to improve the safety and performance of Li-CO2 batteries. The optimized Li-CO2 cell shows outstanding specific capacity and cycle life, and the post-cycling analysis reveals the degradation mechanism of the electrodes. First-principles calculations based on density functional theory are also performed to understand the interactions between the catalyst and the host electrode. This research demonstrates the potential of MOF cathode catalyst for stable operation in Li-CO2 batteries.

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.
