Abstract
A method for making a positive electrode includes the following steps: dispersing a plurality of carbon nanotubes in water, to form a carbon nanotube dispersion; adding an aniline solution into the carbon nanotube dispersion, to form a mixed solution; adding an initiator into the mixed solution, to form a carbon nanotube composite structure preform; freeze-drying the carbon nanotube composite structure preform in a vacuum environment; carbonizing the carbon nanotube composite structure preform in a protective gas after freeze-drying, to form a carbon nanotube composite structure; and adding a positive electrode active material into the carbon nanotube composite structure. The present application also relates to the positive electrode and a battery including the positive electrode.
