"materials cheap, available in large quantities and non-toxic... equally conductive in all three spatial directions and temperature-resistant up to 400 C... supercapacitors... very high power density... can be charged many times faster than conventional batteries. While supercapacitors store far less energy than batteries these new electrode materials are intended to reduce this gap.... also suitable for the thin-film processes often used in industry for application on substrates... LEDs and solar cells"
