In September 2025, GRAPHERGIA’s partner, the  Institute of Materials Research of DLR (German Aerospace Center), presented an abstract at the 9th International Symposium on Materials for Energy Storage and Conversion (mESC‑IS 2025).  This abstract, entitled “Ionic liquid integrated high-voltage polymer gel electrolyte to improve the capacitance and cyclic stability of supercapacitors”, was presented by Dr. Apurba Ray, who is the co-author of the publication with Professor Bilge Saruhan (both from DLR, Germany).

Introduction to the abstract:

With the rapidly increasing demand for the most promising electrical energy storage devices, supercapacitors (SCs) have attracted widespread interest due to their high capacity, specific power density and long cyclic performance. To date, symmetric electrodes made of various types of porous carbons such as activated carbon (AC), carbon nanofibers, carbon nanotubes (CNT), and graphene/reduced graphene oxide (rGO) are commonly used for commercial electrical double-layer capacitors (EDLCs) or supercapacitors. Electrolytes also play an important role for supercapacitor devices through their physical, thermal and electrochemical properties.
