Porous Multicomponent Mn–Sn–Co Oxide Microspheres as Anodes for High-Performance Lithium-Ion Batteries

[Image: see text] Porous multicomponent Mn–Sn–Co oxide microspheres (MnSnO(3)–MC400 and MnSnO(3)–MC500) have been fabricated using CoSn(OH)(6) nanocubes as templates via controlling pyrolysis of a CoSn(OH)(6)/Mn(0.5)Co(0.5)CO(3) precursor at different temperatures in N(2). During the pyrolysis process of CoSn(OH)(6)/Mn(0.5)Co(0.5)CO(3) from 400 to 500 °C, the part of (Co,Mn)(Co,Mn)(2)O(4) converts into MnCo(2)O(4) accompanied with structural transformation. The MnSnO(3)–MC400 and MnSnO(3)–MC500 microspheres as secondary nanomaterials consist of MnSnO(3), MnCo(2)O(4), and (Co,Mn)(Co,Mn)(2)O(4). Benefiting from the advantages of multicomponent synergy and porous secondary nanomaterials, the MnSnO(3)–MC400 and MnSnO(3)–MC500 microspheres as anodes exhibit the specific capacities of 1030 and 750 mA h g(–1) until 1000 cycles at 1 A g(–1) without an obvious capacity decay, respectively.
