Abstract

Abstract : This paper describes the synthesis of double shelled hollow SnO2 /P(EGDMA- co -MAA) microspheres as anode material for lithium ion batteries. Abstract : Double shelled hollow tin dioxide/poly(ethyleneglycol dimethacrylate- co -methacrylic acid) (SnO2 /P(EGDMA- co -MAA)) microspheres were prepared by selective removal of the silica inner core via etching with hydrofluoric acid from the corresponding SiO2 /SnO2 /P(EGDMA- co -MAA) tri-layer microspheres. These tri-layer microspheres were synthesized using a combination of the modified Stöber method for the silica inner core, a hydrothermal technique for the sandwiched SnO2 layer and distillation precipitation polymerization for the coated P(EGDMA- co -MAA) shell-layer. The double shelled hollow microspheres were utilized as anode materials for lithium ion batteries, which had a significantly enhanced cycling performance compared to when neat SnO2 hollow spheres were used.
