To solve the low conductivity and huge volume change of cobalt-based anode, the tuneable Co3O4structure is constructed through a template-free hydrothermal strategy and calcination under different atmosphere. Multi-shelled Co3O4(MS-Co3O4) and pomegranate-like Co3O4encapsulated in carbon (CS-Co3O4@C) are fabricated from the same micron-sized cobalt-based polymeric precursor. MS-Co3O4manifests a capacity of 1195 mAh·g−1at a current density of 200 mA·g−1and delivers an initial coulombic efficiency (ICE) of 80.3%. In addition, CS-Co3O4@C delivers a reversible capacity as high as 676 mAh·g−1at 2000 mA·g−1after 500 cycles. Such high capacity, remarkable cycling and rate performances are attributed to hollow multi-shelled structure and carbon network skeleton, which promote the initial coulombic efficiency, relieve volume change and facilitate the migration of Li-ion.
