Powering up energy storage: Estonian tech nominated for prestigious prize
Three Estonian scientists have been nominated for European Patent Office (EPO) prize for developing superior carbon-based materials for the energy storage devices known as ultracapacitors. The invention uses a material called curved graphene, which increases the amount of energy stored by the ultracapacitors. Inventors state their ultracapacitors can charge within 15 seconds, withstand over one million charge cycles, and are free from toxic materials.
