The innovation potential increases going from the inner to the outer regions of the radar chart. Target values are chosen based on best available option on the market: 3.0 V maximum operating voltage (maximum cell voltage for industrial supercapacitor devices), 65 mS/cm ionic conductivity (using Acetonitrile as a solvent in electrolytes), registered REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) status for commercial availability, toxicity comparable to Propylene Carbonate (electrolyte component used in various commercial electrochemical energy storage devices) and <10 EUR/kg material cost (cost target for industrial electrolytes).
