Sn(OH)4　colloids　were　synthesized　by　a　sol　process.　The　particle　size　could　be　controlled　via　the　addition　of　active　carbon.　The　SnO2/C　was　obtained　after　sintering　in　Ar2.　The　nano-sized　particles　of　SnO2　were　transferred　to　the　surface　of　LiNi1/3Co1/3Mn1/3O2　by　a　carrier　transfer　method.　The　influence　of　procedure　conditions　on　the　particle　size　of　nano-sized　SnO2　and　its　precursors　were　investigated.　The　result　show　that　the　particle　size　of　the　precursors　can　be　controlled　by　adding　active　carbon　as　a　carrier　and　sodium　dodecyl　benzene　sulfonate　as　a　surfactant　after　ageing　for　12　h.　SnO2　particles　were　coated　on　the　surface　of　LiNi1/3Co1/3Mn1/3O2.　The　electrochemical　property　was　improved　due　to　the　modification　of　nano-sized　particles　of　SnO2.　The　initial　discharge　capacity　is　increased　by　3.75%,　0.96%,　6.41%　and　8.71%　at　the　rate　of　0.5C,　1.0C,　2.0C　and　5.0C,　respectively.　The　capacity　retention　increases　to　92.14%　and　the　pristine　is　71.35%　at　1.0　C　after　50　cycles.　©,　2015,　Chinese　Ceramic　Society.　All　right　reserved.
