Our work

The overall objective of the ARMS project (Atomic layer-coated gRaphene electrode-based Micro-flexible and Structural supercapacitors (ARMS)) is to integrate comprehensive materials and processes, including 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 totally eco-friendly supercapacitors with energy density reaching > 50 Wh/kg that is comparable to batteries without sacrificing the power density, cycle life or eco-friendliness, and open up opportunities to establish a new value chain for supercapacitor manufacturing with European SMEs as key players.

 
Unveiling the inner world of the activated carbon

Activated carbon, produced by heating organic matter in the absence of oxygen and then undergoing activation, is an incredibly versatile material with applications ranging from soil improvement and water purification to energy storage. While our colleagues from the Latvian State Institute of Wood Chemistry have provided valuable insights into surface area, pore volume, and pore size distribution, we at the Institute of Solid State Physics, University of Latvia (ISSP UL) see beyond the carbon’s surface.
