Investigation of a space propulsion concept using inertial electrostatic confinement
… confinement (IEC) grids that are asymmetrically designed. In this study, which used argon as a propellant, a retarding potential analyzer (RPA) was used to measure the exhaust of HIIPER, and results showed the presence of electrons and ions, with ion energies equal to the helicon bias voltage and …

Thermodynamics and kinetics of Mg intercalation for multivalent cathode applications
… MV metal anode (such as Mg) with a high voltage cathode has the potential to surpass the energy densities achieved by current Li-ion batteries, along with improved safety and lower costs. However, moving into newer chemistries leads to newer challenges, such as developing cathodes that can …

Thermodynamic stability of perovskite and lanthanum nickelate-type cathode materials for solid oxide fuel cells
… with the oxygen reduction reaction(ORR) at the cathodes. Hence, improving the cathode design will greatly enhance the overall performance of SOFCs. Lanthanum nickelate, La2NiO4+δ (LNO), is a mixed ionic and electronic conductor that has competitive surface oxygen exchange and transport …

Analysis of Ionomer-coated Carbon Nanofiber for use in PEM Fuel Cell Catalyst Layers
… over the last two decades. A new electrode design with improved control over factors such as ionic and electrical pathways, porosity, and catalyst placement, could allow the application of less expensive catalyst alternatives. In this work, a novel electrode design based on ionomer-coated …

Design and synthesis of Ni-rich and low/no-Co layered oxide cathodes for Li-ion batteries
… requirements of different application scenarios. Cathodes are an essential component of LIBs, which governs the performance of commercial LIBs. Layered transition metal oxide, i.e., LiNixCoyMn1-x-yO2 (NMC), is one family of cathodes that are widely applied in the prevailing commercial LIBs. With …
