What if your mobile phone had:

  • a processor and memory which drained 1/10th of the power?
  • a safe battery with three times the energy density and 10 times more charge?
  • a transparent solar coating so that the battery could be recharged by the sun?
  • a display with a quarter of the thickness, drawing 1/3 of the power and was unbreakable?
  • half the weight that it does today?

Your phone would need charging once a month and replacing once a decade. Today’s excellent technologies operate at a level way below the scientific limits to performance. Royce can turn the possibilities above into reality.

Energy Efficient ICT focuses on:

Energy Generation: new materials that are able to power autonomous devices by harnessing energy from the environment.

Energy Storage: significant improvements in the energy density, longevity, cost and compatibility of the various energy storage technologies required to power the next generation of ICT devices.

Energy Use: radical approaches to reduce power consumption in processing and memory, towards the theoretical limits that are many orders of magnitude below current silicon-based technology, and making devices more lightweight.


Royce@ Cambridge works closely with the Imperial/Leeds ‘Atoms to Devices’ core area, particularly in materials nanofabrication. Connections with the Oxford-led ‘Energy Storage’ core area are already established and there is a natural complementarity between large-scale storage in Oxford and the smaller-scale novel battery systems under study in Cambridge. ‘Chemical Materials Discovery’ led by
Liverpool provides a natural link for the identification and development of very new functional materials systems. The Manchester-led ‘2D Materials’ core area has excellent links with Cambridge through the Graphene Centres at both institutions.
