A Covalent 3D CNT@rGO Nano-Hybrid for High-Efficiency Conductivity in Lithium-Ion Batteries.

ABSTRACT: The limitations of conventional conductive agents in lithium-ion batteries, such as carbon black and graphite flakes, have driven the search for high-performance alternatives. Carbon nanotubes (CNTs) and graphene offer exceptional conductivity and lower dosage requirements, but face challenges related to high costs and complex fabrication processes. Herein, we develop a facile and cost-effective one-step chemical vapor deposition (CVD) strategy to achieve ultrahigh-yield CNT growth (7692.31%) on reduced graphene oxide (rGO), constructing a covalently integrated 3D CNT@rGO composite. When deployed as a conductive agent in LiFePO₄ cathodes, the 3D architecture establishes multidirectional conductive networks that facilitate unimpeded electron/ion transport during electrochemical r
