Summary: Polyaniline, the most famous conducting polymer, has poor utilization of its theoretical capacity and inferior cycling stability. In this study, its fully reduced form, leucoemeraldine base (LB), is investigated as an alternative to the commonly used emeraldine salt and base (ES and EB). LB shows significantly improved capacity utilization (92%) and cycling stability (84% capacity retention after 1000 cycles). This work enhances our understanding of polyaniline and promotes its practical application as a low-cost, high-performance, sustainable, and green cathode material for energy storage devices.

Summary: Quinoxaline (Q) is a promising anolyte active material in nonaqueous redox flow batteries due to its high solubility and low reaction potential. This study investigates the effect of ion species on Q reaction in acetonitrile solvent through electrochemical measurements and theoretical analysis. The results show that Q exhibits excellent electrochemical reversibility and a low-reaction potential under tetrabutylammonium hexafluorophosphate (TBAPF(6)) conditions, making it a very promising candidate for anolyte active materials. The coupling of Q with the catholyte 1,4-di-tert-butyl-2,5-bis (2-methoxyethoxy)benzene (DBBMEB) demonstrates a high-voltage and high-energy-density redox flow battery.

Summary: Increasing concentrations of redox-active species in organic redox flow batteries can improve viability but can also lead to inefficient electrochemical cycling and low material utilization at higher current densities. We studied a highly soluble and stable redox-active couple, N-(2-(2-methoxyethoxy)ethyl)phenothiazine (MEEPT), and its bis(trifluoromethanesulfonyl)imide radical cation salt (MEEPT-TFSI), and demonstrated robust cycling performance with 1 M electrolyte concentration, achieving 94% materials utilization, 89% capacity retention, and 99.8% average coulombic efficiency over 435 h (100 full cycles). This study establishes the potential for high-performing, concentrated nonaqueous electrolytes while highlighting possible failure modes in such systems.

Summary: Flowable suspension-based electrodes (FSEs) have gained attention due to their improved performance and flexible operation in electrochemical flow cells. However, FSEs can exhibit non-Newtonian characteristics under certain conditions, causing large pumping losses and flow-dependent transport rates. In this study, a one-dimensional model integrating porous electrode theory and FSE rheology is developed to explore scaling relationships and design rules for electrochemical devices. The model identifies key dimensionless groups and establishes property-performance relationships for FSEs, providing guidance for practical operating envelopes.

Summary: Reducing the platinum (Pt) loading in polymer electrolyte fuel cells (PEFCs) is important for their widespread use, but it leads to polarization losses at higher current densities. The morphology of carbon supports in PEFC cathodes affects the deposition of Pt, resulting in different kinetic and transport resistances. In this study, we develop a model to differentiate the sink terms for Pt on the surface and in the pits of carbon supports, and assess the impact of nanoscale ohmic resistance on PEFC performance. We estimate the micropore resistances based on experimental local oxygen transport resistances and simulate polarization curves to evaluate the effect of micropore resistance.

Summary: Redox flow batteries (RFBs) face challenges due to complex failure modes, such as membrane crossover, leading to reduced capacity and cycling efficiency. Redox-active oligomers (RAOs) are proposed as a solution, but their impact on flow cell performance is not well understood. This study shows that oligomeric derivatives of TEMPO have lower diffusivities but maintain good charge transfer characteristics. The variations in mass transport rates lead to differences in flow cell polarization and cycling performance.
