Abstract Sn-based oxides have been considered as promising anode candidates for lithium-ion batteries (LIBs), but their commercialization is always impeded by severe volume expansion and unsatisfactory electron conductivity. In order to overcome these disadvantages, a novel SnO2/C nanocomposites are devised and fabricated via a 3D-network composite-gel precursors derived from macromolecule polyacrylamide, in which ultrasmall SnO2 nanocrystals (
