We report a flash Joule heating method for the rapid preparation of graphene-like materials. The L-GHS exhibited a uniform diameter of 200 nm and an ideal specific surface area of 670 m² g⁻¹. Meanwhile, the specific capacity of L-GHS remained at 942 mA h g⁻¹ after 600 cycles (1 A g⁻¹), which shows excellent electrochemical performance.
