As a three-dimensional lithiophilic current collector, we created a hollow Co 3 [Co 6 ] 2 embedded high-conductivity carbon film. Both experimental estimation and experiment show that lithiophilic hollow CoCoPBA nanoparticles provide abundant active sites due to their large surface area, effectively reducing nucleation overpotential and making lithium deposition simpler and more uniform. According to h-CoPBAs@SWCNT electrodes, they have a flat and uniform Li deposition morphology, which is useful in prolonging lithium metal anodes' cycle life.
