Abstract

Abstract : A melt infiltration method is developed to encapsulate SnO2 nanocrystals into porous carbon as a high-performance lithium storage material. Abstract : A simple and scalable melt infiltration method has been developed to encapsulate SnO2 nanocrystals into a hierarchically porous carbon matrix as a high-capacity lithium storage material. SnO2 nanocrystals in a three-dimensional carbonaceous network are obtained via melt infiltration of SnCl2 and subsequent in situ conversion. The SnO2 –carbon composite delivers high capacity with a long lifespan of over 800 cycles. Such a method provides an efficient strategy to encapsulate active materials into porous carbons with superior electrochemical performance.
