Research Interest

Nano Materials and Thin Films for Electrochemical Energy Storage and Conversion

Ever-shrinking applications such as smart cards, miniature remote sensors, RFID tags, and medical implants are creating an ever-growing need for smaller and thinner batteries to power the devices. Short ion diffusion path enables high-power capability of thin-film batteries. One of the key drawbacks of these batteries is limited scalability for applications that demand high areal energy density. The effective surface area of an electrode can be increased without increasing its physical size by depositing thin films on the high-aspect-ratio 3D-perforated substrates and using materials with very fine particle size. This can boost both: the surface area of the electrodes and their volume by orders of magnitude, enabling high current rates to be achieved in conjunction with high energy values per battery footprint. Our research is focused on the development of simple and inexpensive electrochemical synthesis of nanoparticle high-performance battery materials for coating of irregular surfaces, such as in three-dimensional thin-film microbatteries, which break the classical battery energy-power compromise.

Enhancing the lithium-ion conduction of polymer electrolytes for all-solid-state lithium and lithium-ion batteries is by now an old theme, and there has been much research done over the years. However, the problem of obtaining polymer electrolytes (PE) with sufficiently high conductivity (>1mS/cm) still persists, and is still relevant from both scientific and technological points of view. We recently presented a procedure for orienting the polyethylene-oxide (PEO) helices in the perpendicular direction by casting the PEs under a magnetic field, which enhances the ionic conductivity of the plane perpendicular to the film by about one order of magnitude. The magnetic-field effect is even more pronounced in polymer electrolytes with incorporated diamagnetic and ferromagnetic nano-fillers. Our current efforts address the original research approach for the development of single-molecule, orthogonally-oriented ion-conducting polymer channels (helices) by the attachment of nanosize core-shell magnetic particles to the end groups of the polymer helix, followed by casting of a polymer electrolyte film under a gradient magnetic field.

Current Main Projects (together with Prof. E. Peled):
