On July 10, 2025, a team from the School of Materials Science at Tsinghua University published research results in Nature Materials, revealing that gas-phase white carbon black can serve as an ideal catalyst support for the growth of carbon nanotubes. By chemical vapor deposition, acetylene is decomposed into carbon atoms at 850 ℃, forming a 2-5nm diameter single-walled carbon nanotube array on the surface of gas-phase white carbon black. Experimental data shows that the conductivity of the material reaches 1.2 × 10 ⁴ S/cm, which is three times that of traditional carbon black. At present, CATL has reached a cooperation agreement with the research and development team, planning to apply it to the next generation of solid-state battery current collectors, which is expected to reduce battery internal resistance by 15%.
