A new architecture for lithium-ion battery anodes has the potential to enable portable electronics to be charged in 10 minutes instead of hours.
Researchers at the University of California, Riverside (UCR) developed the three-dimensional, silicon-decorated, cone-shaped carbon-nanotube cluster architecture for lithium-ion battery anodes. Silicon has a total charge capacity that is 10 times higher than commercial graphite-based lithium-ion battery anodes, and would potentially result in a 63% increase of total cell capacity and a battery that is 40% lighter and smaller.
The UCR team developed the architecture via chemical vapor deposition and inductively coupled plasma treatment.
The researchers say lithium-ion batteries based on the novel architecture demonstrated a high reversible capacity and excellent cycling stability. Moreover, they showed excellent electrochemical stability and irreversibility even at high charge and discharge rates, nearly 16 times faster than conventionally used graphite-based anodes.
