【 摘 要 】

tsA novel hierarchical structure constructed by encapsulating cobalt sulfide nanowires within nitrogen-doped porous branched carbon nanotubes (NBNTs) is designed for lithium-ion batteries.The unique hierarchical Co9S8@NBNT electrode displayed a reversible specific capacity of 1310 mAh g−1 at a current density of 0.1 A g−1.
