PURPOSE: A secondary battery is provided, to improve the discharging capacity and to enhance the rate capability by using the carbon nanotube as a conducting material. CONSTITUTION: The secondary battery comprises a positive electrode, an electrolyte and a negative electrode, wherein carbon nanotubes are used as a conducting material providing the moving channel of reactant materials and the moving channel of electrons. The carbon nanotube can be replaced by carbon nano-wire or carbon nano-particle. Optionally the mixture of the carbon nanotube and carbon black is used as a conducting material. Preferably the secondary battery is a sulfur-based secondary battery comprising a Li/S battery, a Li/FeS battery, a Li/Ti2S battery and a Li/organosulfur battery, or a lithium-based secondary battery comprising a lithium ion battery, a lithium polymer battery and a Li/MnO2 battery.
