Abstract:Carbon materials have been favored as lithium-ion battery anodes in both research and commercial field. This work presents a simple, scalable production namely “triple-boost” method to synthesize hierarchical porous carbon anode for Li ion storage. The polymerization of acetylacetone (Hacac) forms the precursor of carbon, while nickel acetylacetonate (Ni(acac)2), Fe3O4 nanoparticles, and 5-phenyl tetrazole are mixed to the precursor as three boosters, which dramatically improve the performance of lithium-ion battery (LIB). The obtained hierarchical porous carbon anode material has a high charge capacity of 1125.2 mAh·g−1 at a current density of 0.1 A·g−1, and it also exhibits a high-rate performance of 523.3 mAh·g−1 at a current density of 5 A·g−1. Meanwhile, 1000 cycles under 0.5 A·g−1 current density indicates its long cycle life, as the capacity attenuation of each cycle is only 0.008 %.
