An electrode comprising a three-dimensional heteroatom doped carbon nanotube macromaterial

摘要

An electrode comprising an anode and / or cathode comprising a three-dimensional boron doped carbon nanotube macromaterial is disclosed.The anode and / or cathode can be prepared using chemical vapor deposition using a metal foil, such as copper foil, as a substrate, or in other embodiments, bonded to the metal foil after the preparation.The anode and / or cathode are porous and a portion of the pores may be filled with an appropriate anode or cathode active material.The preferred active material of the anode comprises lithium metal or lithium containing alloy.The preferred active material of the cathode comprises lithium salts such as lithium oxide or lithium sulfide.Batteries, capacitors and supercapacitors having these anodes and / or cathodes are also disclosed.
