Nano Materials and Thin Films for Electrochemical Energy Storage and Conversion
In our group, four projects are related to nano science and technology. We have developed a nano-porous proton-conducting membrane with a typical pore size of 1.5nm. On the basis of this membrane we have developed a direct methanol fuel cell and a direct ethylene glycol fuel cell which, at time of writing, have demonstrated the highest recorded power densities (0.5 and 0.32W/cm2 respectively). We are studying synthesis routes for highly active nano-size platinum-alloy catalysts (2-5nm in size) for use in hydrogen and in alcohol fuel cells (in collaboration with Prof. Golodnitsky). We have developed and demonstrated the first on-chip three-dimensional thin-film lithium-ion microbattery (collaboration with Prof. Golodnitsky and with Prof. Nathan of the Faculty of Engineering). In collaboration with Prof. Golodnitsky, Prof. Scrosati (
We were the first to develop a procedure for orienting the helices of poly ethylene oxide (PEO) in the orthogonal direction by casting the film under magnetic field (MF), the result of which is a one-order-of-magnitude increase in polymer electrolyte (PE) conductivity and a similar decrease in PE/lithium electrode interfacial resistance (in collaboration with Prof. Golodnitsky).
