YUNASKO recently participated in Electrical Energy Storage Applications and Technologies (EESAT) conference in San Diego, CA during October 11-13, 2017.
EESAT is the premier energy storage technical meeting which has proven to be at the international forefront of advancing leading-edge research, development, and deployment of energy storage ideas, projects and challenges. The 2017 EESAT theme is “Energy Storage Evolution and Revolution”. This year’s meeting provides a format to revisit critical, turning point research coupled with new frontiers in technology development and emerging applications for the smarter modern electricity grid.
Dr. Sergii Tychina, YUNASKO new business development manager presented company’s approaches to improve performance of ultracapacitors, namely increasing energy and power densities.
Increase in power density was obtained due to a number of improvements including an approach based on studying the electrolyte in-pore mobility in positive and negative electrodes. It enables to substantially increase the ultracapacitor power output to about 100 kW/kg and efficiency to over 99.0%.
However, the low energy density is still a weak point of all the ultracapacitors that does close many doors to the market. An increase in energy has been achieved due to so-called parallel hybridization of the electrode/electrolyte system, wherein both positive and negative electrodes contain nanoporous carbon and Li-intercalated metal oxides as balanced mixtures.
