Supercapacitors in Aqueous Electrolyte Reaching the Performance of Organic Electrolyte-Based Systems (Electric Vehicles: Everything is Changing)

AC/AC capacitors using mixed salt aqueous electrolyte operate up to 1.6 V while taking advantage of pseudocapacitive contributions related with redox reactions at the carbon/electrolyte interface. Consequently, the energy density reaches that of systems based on organic electrolyte. The use of a special antifreezing additive allows the operating temperature range to be extended down to -40°C.

Elżbieta Frąckowiak is full professor in the Institute of Chemistry and Technical Electrochemistry at Poznan University of Technology, Poland.

She is involved in research devoted to storage and conversion of energy - electrochemical capacitors, lithium-ion batteries, fuel cells, hydrogen electrosorption into carbon materials. Activated carbons, carbon nanotubes, carbons enriched in heteroatoms (nitrogen, oxygen), graphenes, conducting polymers, composites and redox active electrolytes are the most often used materials for her research.

Chair of Division 3 "Electrochemical Energy Conversion and Storage" in the International Society of Electrochemistry (2009-2014). She is a member of the International Advisory Board of the journal Energy & Environmental Science from 2008.

Laureate of the prestigous Award of the Foundation for Polish Science (2011). She was decorated with Oficer Medal of Restituta Polonia (2011) and Medal Sapienti Sat (2012). Member of the Polish Academy of Sciences (2013) and the Fellow of the Royal Society of Chemistry (2014).

Author of over 150 publications, a few tens of patents and patent applications, 22 chapters, co-editor of 2 books. Her number of citations exceeds 9 900, Hirsch index is 44.
