Abstract
A lithium ion battery includes at least one cathode electrode, at least one anode electrode, and an electrolyte. The cathode electrode includes at least one first carbon nanotube paper and at least one cathode electrode plate. The cathode electrode plate locates on a surface of the at least one first carbon nanotube paper, and includes a plurality of stacked first carbon nanotube films. A cathode active material is dispersed in the plurality of first carbon nanotube films. An anode electrode includes at least one first second carbon nanotube paper and at least one first anode electrode plate. The anode electrode plate is located on a surface of the at least one first second carbon nanotube paper, and includes a plurality of stacked second carbon nanotube films. An anode active material is dispersed in the plurality of second carbon nanotube films.
