Carbon coated nanoporous SnOxSb@C alloy has been fabricated and applied as anode in LIBs. It delivers a high capacity of 850 mA h g−1 and high-rate performance by synergetic enhanced electronic/ionic conductivity.
Ultrasmall Co3O4 nanoparticle with thin porous carbon shell is reported by employing metal–organic framework as precursor and CO2 as oxidizing atmosphere, which exhibits a long cycling stability and high rate performance for Li-ion battery.
