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.
