New Non-Platinum Fuel Cell Catalyst

The Kisailus research group at the University of California, Riverside, has  developed a novel fuel cell catalyst made of porous carbon nanofibers doped with inexpensive metal or metal oxide nanoparticles that provide active sites for energy conversion and storage. The active or catalytic nanoparticles are embedded and integrated with graphitic nanofibers and are accessible to the surrounding environment due to high porosity. The extensive graphitic networks within these nanofibers also exhibits enhanced conductivity. Cobalt oxide- graphite composite nanofibers showed equivalent catalytic activity to fuel cell platinum catalysts like platinum on carbon (Pt/C). When operated under fuel cell conditions, the nanofiber formulation provides enhanced durability.  Fig. 1 Metal oxide-graphite composite and porous nanofibers with highly controllable diameter, particle size and performance. Fig. 2 Linear sweep voltametry curves shows that the graphitic nanofibers doped with metal ions have higher current densities than commercial platinum on carbon (Pt/C).

Process to Synthesize Size Controlled Nanocrystalline Materials for Battery Electrodes

Researchers at UCR have developed a scalable and affordable process for synthesizing nanostructure materials like LiFePO4 (LFP) at low temperatures (150 to 200 oC) with highly reproducible sizes and morphologies. The nanocrystalline structures may be utilized as active elements in battery cathodes or anodes to enhance charging cycle stability or enhance capacitance (including when doped with conductive metals). The process is performed at relatively low temperatures, and uses environmentally friendly solvents.  This results in lower up front and ongoing manufacturing costs in cathode and anode production.  The particle size and shape, as well as crystal orientation of the produced structures can be controlled, not only preventing loss of performance and capacity due to increased stresses and charge de-stabilization, but also improving rate capability.  The nanostructures created with this method will result in increased battery power and energy density. Fig. 1: Reproducible nanoprism crystal morphologies produced via the method described here.   Fig. 2: Reproducible nanobelt crystal morphologies produced via the method described here.

Clock Power Reduction Utilizing Adiabatic Charging Method Via a Switched-Capacitor Circuit

Normally, charging a capacitive load from a voltage source invokes a ½ CV2 energy penalty. The concept of adiabatic charging, where the capacitor is charged more slowly than nominally afforded by the natural RC time constant of the charging circuit in the pursuit of reducing energy dissipation to below ½ CV2, has been around for decades. However, there has not been any solution to enabling this slow charging phenomenon in a practical, low-overhead embodiment. For example, prior work used separate DC-DC converters to provide multiple voltage levels, or used resonant inductors, both of which invoke significant area overhead.

Hyperelastic Binder For Printed, Stretchable Electronics

Stretchable electronics are a new, emerging class of electronic devices that can conform to complex non-planar and deformable surfaces such as human organs, textiles, and robotics. Functional fillers incorporated with elastic polymers form composites for use in intrinsically stretchable electronics. These composites can be amenable to high-throughput, low-cost, additive printing technologies that include screen, inkjet, flexography, and 3D printing. However, the properties of the functional and elastic materials used to date have been mutually antagonistic, thus limiting achievement of state-of-the-art functional properties and high elasticity. The present invention relates to the development of random composite inks using triblock copolymer for stretchable electronics. The key novelty offered here is the ability to tolerate higher loadings of inelastic, functional materials without sacrificing the elastic properties of the ink.
