Summary: A quaternized polybenzimidazole (PBI) membrane was synthesized by grafting a dimethylimidazolium end-capped side chain onto PBI. The hybrid membrane exhibited lower swelling ratio, higher mechanical strength, and better oxidative stability compared to the pristine membrane, but the morphology conducive to ion transport was only successfully developed in the pristine membrane. Both membranes showed good alkaline stability at 80 degrees C and demonstrated promising power densities at 60 degrees C for fuel cell applications.

Summary: In this study, polymerized [HVIM]H2PO4 ionic liquids (PIL) were introduced into an OPBI membrane to improve proton transfer and enhance chemical stability. By regulating the intrinsic viscosity of PIL, entanglement between PIL chains and OPBI chains was enhanced to prevent PIL loss and oxidative degradation of membrane materials. The 2.34-PIL/OPBI membrane exhibited the highest proton conductivity of 113.9 mS•cm(-1) at 180°C, which is 3.5 times higher than the original OPBI membrane. It also showed a high remaining weight of 92.1% and lower degradation in mechanical strength and proton conductivity under harsh conditions. This study presents a simple and effective method to enhance the chemical durability of PA-PBI membranes as HT-PEMs by blending PIL with OPBI.

Summary: Highly concentrated aqueous binary solutions of acetate salts show potential for electrochemical applications, including energy storage. These solutions have high solubility and can reduce ion activity, leading to better stability of the electrolyte. The addition of Li+ or Na+ allows compatibility with intercalation materials, making them suitable for rechargeable alkaline-ion batteries. However, a deeper understanding of their physicochemical properties is still needed.

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.
