Summary: The relatively lower power density of Microbial fuel cells (MFCs) is primarily due to weak biofilm habitation and sluggish extracellular electron transfer at the anode interface. To address this challenge, porous CoFe2O4 nanoparticles were used as anode electrocatalysts to facilitate biofilm formation and enhance electron transfer. Experimental results showed that MFCs equipped with CoFe2O4 anode achieved a maximum power density approximately 3.4 times higher than that of the pristine carbon cloth, and the biofilm density and viability on the anode were improved.

Summary: Microbial fuel cells (MFCs) have great potential for recovering electrical energy from waste and biomass, but their practical application is hindered by inefficient power production and high costs. In this study, a bacteria/electrospun oriented carbon nanofibers integrating with carbon nanotubes (BEO-CNFs/CNTs) anode was developed to enhance MFC performance. The BEO-CNFs/CNTs anode greatly improved bacterial loading content and extracellular electron transfer (EET) efficiency, leading to a significantly higher power density than other anodes. This research provides a new perspective for preparing efficient anodes using electrospinning technology.

Summary: This research successfully increased the power density of microbial fuel cells (MFCs) by designing a new type of anode electrocatalyst, Fe/N-3 @ CNFs. Fe/N-3 @ CNFs have a porous structure with uniformly distributed Fe nanoparticles, providing a larger surface area for the survival of electroactive bacteria and enhancing electron transfer efficiency. Electrochemical measurements showed that Fe/N-3 @ CNFs exhibited excellent electrocatalytic activity, with a maximum power density 1.8 times higher than Fe@CNFs and 3.6 times higher than carbon cloth. Additionally, the study found that the addition of melamine increased the electronic conductivity of the carbon matrix and promoted the abundance of electroactive bacteria and the release of positively charged iron mediators.

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.
