Lithium-ion batteries (LIBs) can store considerable green and clean energies. Meanwhile, as environment-friendly second batteries, LIBs have high energy density and power density. As anode materials for LIBs, SiO2 is one of the most abundant and eco-friendly sources on the earth. Although it has high theoretical capacity (1965 mAh g-1), SiO2 particles due to its low conductivity and poor mechanical property can’t be widely applied in the field of LIBs. To solve above problems, carbon modification has been elucidated to effectively enhance the electrochemical performance of SiO2-based anodes. We adopted a facile method to prepare attapulgite (AT)/polyacrylonitrile (PAN) aerogel precursor and then the precursor was pre-oxidated and carbonized. We expected AT-based aerogels contributed to high specific capacity and PAN provided high structural integrity and electric conductivity.
