Electrochemical properties of SnO2 nanoparticles immobilized within a metal-organic framework as an anode material for lithium-ion batteries

SnO2 nanoparticles have been immobilized inside MIL-101(Cr) crystals achieving the novel SnO2@MIL-101(Cr) anode material with a multiple-core/shell structure. Under the protection of MIL-101(Cr) shell, the pulverization and aggregation of SnO2 during cycling have been diminished. Both good cyclability and rate capability with a reversible capacity of similar to 510 mA h g(-1) at 0.1C after 100 cycles have revealed.
