A new simple process for synthesis of heterogeneous yolk‐shell microspheres is introduced. The core/shell‐structured microspheres are prepared by a one‐pot spray pyrolysis process. The removal of one kind of metal oxide by a dry process produces heterogeneous yolk‐shell microspheres. The yolk‐shell Sn@C microspheres show superior electrochemical properties as anode materials for lithium‐ion batteries.
