Hybrid Electrolyte Supercapacitor

A new and patented type of supercapacitor electrolyte that. It makes it possible to combine the benefits of a classic aqueous and a modern organic electrolyte in one system, thanks to a unique interface control and nanotechnology. This means that the new technology has made it possible to produce a supercapacitor with a much larger voltage window than what can normally be obtained in an aqueous electrolyte, while still offering the high conductivity, lower price, and far more environmentally friendly material technology that are characteristic of an aqueous electrolyte.


  1. Consultant fees that InnoCell has requested
  2. Challenges with access to SDU’s Roll2Roll production method Further development into a production model with nearly doubled energy density compared to current supercapacitors, while also halving production price. InnoCell will collaborate with NanoSyd (MCI), as a Roll2Roll production method may be used for scaling.

Solution idea

  1. Follow-up regarding solicitation of bids for consultancy portion
  2. Assist with access to Roll2Roll

Project deliverables

  • Development of a reliable Roll2Roll production method (NanoSyd MCI and InnoCell)
  • Upscaling of material production (InnoCell)
  • Lifetime determination and material optimisation (CIE MCI and InnoCell)
  • Development of packaging technique (ERD and InnoCell)
  • Development and demonstration of supercapacitor-based converter system (ERD ApS and CIE)
