Silicon/carbon (Si/C) nanocomposites have recently received much attention as Li-ion battery negative electrodes due to their mutual synergetic effects in capacity and mechanical integrity. The contribution of Si the total Si/C determines structural efficiency. Herein, we report on a multi-layered, one-dimensional nanostructure that exhibits theoretical specific nanocomposite. Concentrically tri-layered, compartmentalized, C-core/Si-medium/C-shell nanofibers were fabricated by triple coaxial...
Through controlling the cross-linking and thickness of low-cost methylated polybenzimidazole anion exchange membranes by using imidazolium chloride as a catholyte additive, we improved energy efficiency at current density 100 mA cm–2 for all-vanadium redox flow batteries (RFBs) to 82%, compared 76% with Nafion 212 membrane 67–78% previously reported standard electrolyte. Moreover, thermal stability analysis charged catholytes, direct observations vanadium precipitation variable temperature...
ABSTRACT Sulfonated copper phthalocyanine (CuPCSA) was embedded into Nafion membranes in ratios of 0, 1.25, 2.5, 5, and 7.5 wt %. The absence CuPCSA related peaks WAXS patterns indicated that did not form crystalline phases during membrane formation. Tensile strength Young's modulus were highest the range 2.5–5 % CuPCSA. As demonstrated for 212, weight gain swelling water‐based solutions decreases when sulfuric acid concentration increases from 0 to 2 M. In M acid, addition gain. contact...
Enhancing the durability of polymer electrolyte membrane fuel cells (PEMFCs) is critical for advancing a hydrogen‐powered clean energy future. A major obstacle to improving PEMFC reactive oxygen species (ROS) that deteriorate performance by oxidizing electrode assembly (MEA). While CeO x ‐based nanomaterials are widely used as antioxidants, they often undergo decline in efficacy their nanostructure deformation, hampering stable operation. Here, mesoporous silica nanoparticles (MSNs) reported...
