CARBON NANOTUBE-BASED ELECTRODE AND RECHARGEABLE BATTERY

摘要

Carbon nanotube-based electrode materials for rechargeable batteries have a vastly increased power density and charging rate compared to conventional lithium ion batteries. The electrodes are based on a carbon nanotube scaffold that is coated with a thin layer of electrochemically active material in the form of nanoparticles. Alternating layers of carbon nanotubes and electrochemically active nanoparticles further increases the power density of the batteries. Rechargeable batteries made with the electrodes have a 100 to 10000 times increased power density compared to conventional lithium-ion rechargeable batteries and a charging rate increased by up to 100 times.
