Abstract
A cathode of lithium-ion battery includes a carbon fiber film. The carbon fiber film includes at least one carbon nanotube film including a number of carbon nanotubes joined end to end and extending along a same direction. Each of the number of carbon nanotubes is joined with a number of graphene sheets, and an angle is between each of the number of graphene sheets and the number of carbon nanotubes.
