Atomic layer-coated graphene electrode-based micro-flexible and structural supercapacitors

  • Start: 01/10/2023
  • End: 30/09/2027

The overall objective of the ARMS project is to integrate graphene-rich bio-based carbon materials and graphene-decorated carbon fibers, and to develop scalable and cost-effective atomic layer deposition (ALD) manufacturing technology to fabricate sustainable supercapacitors with high energy densities (> 50 Wh/kg) comparable to batteries without sacrificing the power density and cycle life to open opportunities to establish a new value chain for supercapacitor manufacturing.

The consortium will achieve this goal by a combination of factors, working in a coordinated fashion: process modification to enable production of high-graphene-content porous carbon for printed flexible energy storage, conformal graphene coating onto carbon fibres for structural supercapacitors, decoration of both types of electrodes with ultra-thin conformal ALD coating of MnO2 and Fe2O3 for increased stability and voltage window (to be scaled up to roll-to-roll), and development of novel, environmentally-friendly electrolytes.

The energy storage devices enabled by this work will be integrated into two use-case demonstrators to show the viability of the concept: 1) a wireless sensor device powered a printed flexible supercapacitor, and 2) a drone powered by structural supercapacitors which are simultaneously structural parts of the drone.
