Research Interest

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 (Rome) and with Prof. Wieczorek (Warsaw) we have developed and characterized a single-ion lithium polymer-electrolyte conductor using anion nano traps. 

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).
