Description
Summary:[Display omitted] •Composite mode from polyacrylamide could be extended to other materials.•A tailored temperature guarantee ultrafine SnO2 and N-doped porous framework.•Unique structure unfolded ultra-high rate performance of 357.8 mAh/g at 12.8A/g.•Facile, scalable and energy saving technology has promising industrial prospects. 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 (
