Lasering Leads to Flexible Graphene Electrodes (2 of 3) (VIDEO)

American Association for the Advancement of Science (AAAS)

Caption

In this movie an LSG electrochemical capacitor is packaged in the ionic liquid 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIMBF4). After charging the electrochemical capacitor at a constant potential of 3.5 V, it is used to light up a red light emitting diode (with a minimum operating potential of 2 V) for about 24 minutes. This image relates to a paper that appeared in the March 16, 2012, issue of Science, published by AAAS. The paper, by M.F. El-Kady at University of California, Los Angeles (UCLA) in Los Angeles, Calif., and colleagues was titled, "Laser Scribing of High-Performance and Flexible Graphene-Based Electrochemical Capacitors."
