Facile Synthesis of a Tin Oxide-Carbon Composite Lithium-Ion Battery Anode with High Capacity Retention

A tin oxide-carbon composite (SnOx-C) was fabricated as a candidate for use as an anode in lithium-ion batteries through the pyrolysis of a ditin citrate precursor. The simultaneous formation of tin oxide and semigraphitized carbon via a facile, solid-state pyrolysis yielded a composite containing tin oxide nanocrystals surrounded by a framework of flexible, porous carbon. Fabrication of tin oxide nanoparticles encased in semigraphitized carbon,...
