Investigations of rate limitation in nanostructured composite electrodes and experiments towards a 3D Li-ion microbattery
… discharge rate limitation within LiFePO4 composite electrode structures have been investigated. It was found that for composite electrodes containing ‘small particles’ of active material solid state processes are not necessarily rate limiting. A simple model has been developed to describe …

Impact of Inert-electrode on the Performance and Electro-thermal Reliability of ReRAM Memory Array
… However, since platinum (Pt) acting as the inert electrode is not an economic choice for industrial production, a Back End of Line (BEOL)-compatible replacement of Pt is highly desirable. A systematic investigation has been conducted and metals such as Ru, Rh and Ir are found to be the best …

Water Management in the PEM Fuel Cell by Incorporating a Novel Siloxane Polymer in the Electrode Layer
… employing a hydrophilic substance COMP-1 in the electrode layer. This modified electrode was hypothesized to prevent the cell from dehydrating by retaining water in the catalyst layer. The improvement would accelerate PEM fuel cell technology to be commercialized in the automotive sector. Through …
