A technical poster on electrochemical supercapacitors, reported by three graduate students and three faculty members from the Chemical & Biomolecular Engineering and Physics departments of Clarkson University, received first place at the annual meeting of the American Institute of Chemical Engineers (AIChE) last semester.

The work, presented as a poster titled "Electrochemical Supercapacitors Based on Polymerizable Ionic Liquids," was authored by Clarkson Professors Ruth Baltus, Sitaraman Krishnan, and Dipankar Roy, in collaboration with graduate students Joshua Close, Surya Moganty and Pubudu Goonetilleke.aiche-poster

The poster received first place among 161 (national and international) posters presented at a technical session of the Materials Engineering and Sciences Division.

Surya Moganty, the primary author of the award-winning poster, is a doctoral student in the Chemical and Biomolecular Engineering department, working under the supervision of Prof. Ruth Baltus, department chair. Joshua Close is a master’s student in the same department, working with Baltus. Sitaraman Krishnan is an assistant professor of chemical and biomolecular engineering. Pubudu Goonetilleke recently received his Ph.D. in physics under the supervision of Dipankar Roy, professor of physics. Goonetilleke has joined the Intel Corporation as a process engineer.

The work is part of Clarkson University’s ongoing research efforts involving novel materials and techniques for sustainable energy storage and conversion.

Electrochemical supercapacitors are efficient systems for the storage and delivery of electrical energy, and they can function in complementary/hybrid modes with certain batteries, such as lithium ion rechargeable batteries.

The Clarkson researchers are developing and characterizing novel materials for advanced supercapacitors that will have high energy-storage capacities, strong resistance against decomposition, as well as a wide range of operational temperatures.

Ionic liquids are low melting organic salts that are liquid at room temperature. The Clarkson team has polymerized these liquids in the presence of carbon nanotubes and is investigating these polymer films for supercapacitor electrolytes.

When sandwiched between thin metal electrodes, these materials can provide small, light-weight supercapacitors that also have rather high charge-storage capabilities. In this compact configuration, the mechanical stability of the device improves, and other problems (such as leakage of electrolytes) associated with liquid-based capacitors are avoided.

Clarkson University launches leaders into the global economy. One in six alumni already leads as a CEO, VP or equivalent senior executive of a company. Located just outside the Adirondack Park in Potsdam, N.Y., Clarkson is a nationally recognized research university for undergraduates with select graduate programs in signature areas of academic excellence directed toward the world’s pressing issues. Through 50 rigorous programs of study in engineering, business, arts, sciences and health sciences, the entire learning-living community spans boundaries across disciplines, nations and cultures to build powers of observation, challenge the status quo, and connect discovery and engineering innovation with enterprise.
