Summary: In this study, a non-aqueous static organic battery using phenothiazine and phthalimide derivatives as active electrolytes was investigated. Among the different derivatives studied, 4-tertiary butyl phthalimide showed excellent performance with high capacity retention, coulombic efficiency, and rate performance. The mechanism of degradation was also studied, revealing that the dimerization of the radical did not affect the redox-active functional group.

Summary: With the rapid growth of renewable sources in electricity generation, the use of grid-scale battery storage is increasing. Aqueous redox flow batteries have the potential to provide safe and scalable energy storage, but high costs have hindered commercialization. The development of a single-flow battery using a multiphase electrolyte offers a low-cost system, but suffers from low Coulombic efficiency. This study compares a theoretical battery model to experimental results, revealing key findings and the need to incorporate gravitational effects in future models.

Summary: Rechargeable aluminum organic batteries (RAOBs) are a promising energy storage device due to the low cost and sustainability of aluminum and organic resources. A redox-active polymer cathode with carbonyl and azo groups was designed and synthesized, showing high capacity, stability, charging capability, and wide temperature range. Fundamental insights into the cathode and electrolyte interface structure were gained through various analysis techniques. The study demonstrates the importance of the alumination/de-alumination reaction and the rich Al2O3- and AlN-based cathode electrolyte interface for the impressive performance of RAOBs.

Summary: Redox flow batteries, specifically membraneless batteries, are being explored for grid-scale energy storage. A mathematical model for membraneless electrochemical cells using single laminar flow between electrodes and different phases of reactants is presented. The study investigates slow and fast reactant transport between phases and shows that increasing nonaqueous phase volume fraction improves battery performance. The analytical approximations agree well with numerical solutions, establishing a useful theoretical framework for single-flow batteries with multiphase flow.

Summary: This study investigates the effects of local field fluctuation introduced by the disorder term on the performance of quantum batteries. The results show that the disorder term can compensate for the disruptive effects of decoherence and improve the performance of quantum batteries. By adjusting the strength of the disorder parameter and choosing a suitable initial state, the amount of free ergotropy and the half-life time of the quantum battery can be enhanced.

Summary: The MTMO (modified TEMPO mediated oxidation) process was used to increase the carboxylic acid group (COOH) content on the surface of lower crystallinity carbon materials (LCCMs), resulting in improved hydrophilicity without defects. The process is environmentally friendly and has advantages such as a recyclable oxidizing agent and room-temperature aqueous treatment. The MTMO-GF electrodes showed improved performance in vanadium ion redox reaction and vanadium redox flow battery tests, with higher current densities and lower charge transfer resistance compared to CH-GF electrodes.

Summary: In this study, a series of polybenzimidazole-polyvinylchloride polymer blends decorated with different quaternary ammonium groups were investigated. The blend with 90% polybenzimidazole content and decorated with DABCO showed superior performance, including low polarization resistance, low swelling, and high stability in acidic media. This suggests that quaternary ammonium functionalized polybenzimidazole-polyvinylchloride systems are excellent candidates for modification or fabrication of thinner membranes to reduce membrane resistance without compromising vanadium blocking properties.
