Interconnected porous NiO@MnO2 nanosheets as anodes with excellent rate capability for lithium-ion batteries
چکیده انگلیسی
Interconnected porous NiO@MnO2 nanosheets are synthesized on nickel foam by hydrothermal method. As an anode of lithium-ion batteries (LIBs), such a architecture could shorten the diffusion distance of lithium ions and largen the contact area between the active material and electrolyte. It displays a high capacity of 1000 mAh g−1 after 160 cycles at a rate of 1.0 C. More importantly, the electrode exhibits an excellent rate performance, it delivers a capacity about 787 mAh g−1 at 5.0 C. The superior lithium storage properties suggest that the interconnected porous NiO@MnO2 nanosheets can function as a promising anode material for high-performance LIBs.
