This material is composed of nanoscale graphene flakes (single-layer or few-layer, thickness <3 nm) combined with porous carbon particles (pore size 2–50 nm, specific surface area 300–1000 m²/g), forming a uniformly dispersed black powder. The graphene provides high conductivity (electrical conductivity >10⁴ S/m) and rapid two-dimensional transport channels, while the porous carbon contributes high specific surface area and abundant pore structures (synergy of mesopores/micropores). The combination creates a hierarchical porous network. It features lightweight (density 0.5–1.2 g/cm³), excellent conductivity, and chemical stability. When used as an electrode material for lithium/sodium-ion batteries and supercapacitors, it can significantly enhance rate performance (high capacity retention at high current densities) and cycle life (>1500 cycles), making it suitable for applications in new energy storage, flexible electronics, and efficient energy conversion.
