Thick NMC-LMO blend positive electrodes were manufactured using dry-powder electrostatic spray deposition (ESD) to avoid the use of unwanted solvents. The effects of two dry powder mixing processes prior to ESD on the dry-made electrodes were investi

Perfluorinated ionomers, in particular, Nafion, are a critical component in hydrogen fuel cells as the ion conducting binder within the catalyst layer in which it can be confined to thicknesses on the order of 10 nm or less. It is well reported that

Physical gels are swollen polymer networks consisting of transient crosslink junctions associated with hydrogen or ionic bonds. Unlike covalently crosslinked gels, these physical crosslinks are reversible thus enabling these materials to display high

Applications of polymer thin films include functional coatings, flexible electronics, membranes and energy conversion. The physical properties of polymer films of nanoscale thicknesses typically differ from the bulk, due largely to entropic effects a

Ion-containing polymers, in particular Nafion, are a critical component in hydrogen fuel cells, where they are not only used as the proton conducting membrane but also as the ion conducting binder within the catalyst layer. Within the catalyst layer,

We have previously shown1,2 that there is a suppression in both swelling and water diffusivity when Nafion is confined to thin and ultrathin films. We have also shown that the modulus of ultrathin Nafion films increases upon confinement3,4, as well a

Proton exchange membrane (PEM)-based fuel cells are being aggressively targeted as an alternative energy source for transportation and stationary power due to their high charge density and low operating temperatures. While the structure, transport an
