Standard rechargeable batteries are only marginally suited for high performance: «To raise the energy density, you need to increase the voltage or the capacity, and that is where
traditional electrode materials and electrolytic fluids reach their limits,» explains the physicist.
Not exact matches
Unlike
traditional supercapacitors, which use the same
material for both
electrodes, the anode and cathode in an asymmetric supercapacitor are made up of different
materials.
Bonaccorso adds that the challenge ahead is to demonstrate a disruptive technology in which two - dimensional
materials not only replace
traditional electrodes, but more importantly enable the design of whole new device concepts.
