摘要	A novel and simple ion-exchange method was developed for the synthesis of nano-SnO/micro-C hybrid structure. The structure of the as prepared nano-SnO/micro-C was directly revealed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). SnO particles with the size about 25 nm were well confined in amorphous carbon microparticles. Carbon matrix in micrometer scale not only acts as a protective buffer for the SnO nanoparticles during the battery cycling processes, but also avoids the shortcomings of nanostructures, such as low tap density and potential safety threats. Electrochemical behaviors of the nano-SnO/micro-C were tested as anode material in lithium ion batteries. The initial reversible capacity is 508 mA h g(-1), and the reversible capacity after 60 cycles is 511 mA h g(-1), indicating good capacity retention ability.
