Abstract

Porous hierarchical NiMn2O4/C tremella-like nanostructures are obtained through a simple solvothermal and calcination method. As the anode of lithium ion batteries (LIBs), porous NiMn2O4/C nanostructures exhibit a superior specific capacity and an excellent long-term cycling performance even at a high current density. The discharge capacity can stabilize at 2130 mA h g-1 within 350 cycles at a current density of 1000 mA g-1. After a long-term cycling of 1500 cycles, the capacity is still as high as 1773 mA h g-1 at a high current density of 4000 mA g-1, which is almost five times higher than the theoretical capacity of graphite. The porous NiMn2O4/C hierarchical nanostructure provides sufficient contact with the electrolyte and fast three-dimensional Li+ diffusion channels, and dramatically improves the capacity of NiMn2O4/C via interfacial storage.
