Sumario:Increasing the energy density of lithium-ion batteries (LIBs) can broaden their applications in energy storage but remains a formidable challenge. Herein, with polyacrylic acid (PAA) as phase separation agent, macroporous Co(2)SnO(4) with hollow skeletons was prepared by sol-gel method combined with phase separation. As the anode of LIBs, the macroporous Co(2)SnO(4) demonstrates high capacity retention (115.5% at 200 mA·g(−1) after 300 cycles), affording an ultrahigh specific capacity (921.8 mA h·g(−1) at 1 A·g(−1)). The present contribution provides insight into engineering porous tin-based materials for energy storage.
