Summary: The development of fast proton-conducting materials with high chemical stability above 100 degrees C is challenging but crucial for PEMFCs. In this study, a benzimidazole-linked COF (PBI-COF) was successfully employed as a fast proton conductor above 100 degrees C for PEMFC applications. The PBI-COF demonstrated excellent proton conductivity, low water swelling, and long-term durability, surpassing many reported proton conductors.

Summary: Commercial proton exchange membrane heavy-duty fuel cell vehicles require a more durable composite membrane that can potentially conduct protons. We developed a composite membrane incorporating silicotungstic heteropoly acid (HPA) and other materials, which showed less swelling, more hydrophobic properties, and higher crystallinity than conventional membranes. This composite membrane demonstrated a proton conductivity of 0.130 +/- 0.03 S cm(-1) at 80 degrees C and 95% RH, and survived more than 800 hours under accelerated stress test conditions.

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.
