Carbon-based composite material, preparation method therefor, and application thereof

Abstract

The invention discloses a carbon-based composite material and its preparation method and application, which belongs to the technical field of carbon material preparation. The carbon-based composite material comprises the substrate, carbon film and structural carbon which are integrated into one body. The electron, ion and atom transmission and chemical structure characteristics of the carbon-based composite materials are modified by the carbon film and structural carbon containing alkali and/or alkali earth elements resulting in the carbon-based composite materials having excellent physical and chemical properties, which can be used for various applications including battery electrodes, capacitor electrodes, various sensors, solar cell electrodes, electrolytic water hydrogen production electrodes, hydrogen storage materials, catalysts and catalyst carriers, composite materials, reinforcing materials.
