Summary: This study constructed a physical model to investigate the impact of different design parameters on the performance of nonaqueous redox flow batteries. The results demonstrated that increasing the concentration of active material and the surface area of the electrode enhanced the kinetics of redox reactions. The modeling also revealed that the local current density was higher near the membrane due to lower ionic conductivity of electrolytes compared to the current collector. Additionally, reducing the electrode thickness and improving the membrane conductivity reduced voltage loss caused by ohmic resistance and improved battery performance.

Summary: The lack of suitable membranes for nonaqueous electrolytes limits cell capacity and cycle lifetime in organic redox flow cells. The study revealed a trade-off between lifetime and Coulombic efficiency, with nonselective separators achieving more stable performance but suffering from low Coulombic efficiencies, while ion-selective membranes achieving high Coulombic efficiencies but experiencing capacity loss over time. Additionally, when electrolytes are premixed prior to cycling, high Coulombic efficiency can be maintained but capacity is lost due to cell imbalance, which can be recovered by electrolyte rebalancing.

Summary: In this article, a new aqueous biphasic system (ABS) with near neutral pH and highly soluble organic/organometallic active species is presented, which effectively prevents crossover due to the thermodynamic separation of active species. This ABS serves as the best example of a Static Membrane-Free Battery, exhibiting the highest maximum theoretical energy density (21.7 Wh L-1), enhanced coulombic efficiency (96%), and stable performance over 250 cycles. Additionally, a novel membrane-free flow-reactor has been specifically designed to maintain a stable liquid-liquid interphase, resulting in a flow battery with a two-fold increase in power density, high coulombic efficiencies, and excellent capacity retention over 100 cycles. This study demonstrates the feasibility of the biphasic electrolyte concept in a truly Membrane-free Flow Battery for the first time.

Summary: Electrochemical Impedance Spectroscopy (EIS) is used as a nondestructive method to quickly characterize the degradation of LIBs. This study applies a physics-based EIS model to interpret the EIS spectra of Li-NMC(5:2:3) half-cell during cycling and relates it to cell capacity degradation. The results show that the polarization impedance increases with the number of cycles, especially in the mid-frequency range. The diffusion coefficient, ionic conductivity, and cathode reaction rate decrease with the number of cycles, with the cathode reaction rate causing the most significant impedance variation. The charge transfer resistance at specific OCVs is linearly related to cell capacity fade beyond 10 cycles.

Summary: 3-ferrocenyl-estra-1,3,5(10)-triene-17-one (2), [Fe(C5H5)(C24H25O3)], crystallizes in monoclinic space group C2. The Cp rings adopt a nearly eclipsed conformation, and the Cp plane is tilted with respect to the substituted phenyl plane. Weak intermolecular interactions such as C-H···π and C-H···O were analyzed. Density functional theory studies revealed a rotational barrier for the C3-O1 bond. Fluorescence quenching and in silico docking studies suggest that human serum albumin forms a complex via van der Waals and hydrogen bonding interactions.
