Sn/SnO embedded in carbon nanosheets as high-performance anode material for lithium ion battery
Source abstract
Abstract
Abstract A facile and scalable strategy is developed to fabricate carbon nanosheets encapsulated Sn/SnO x nanoparticles as anode material for lithium ion battery. In the constructed architecture, the carbon nanosheets can effectively not only avoid the direct exposure of Sn/SnO x to the electrolyte but also suppress the aggregation of nanoparticles and buffer the volume expansion during the charge and discharge process. Electrochemical measurements demonstrated that the Sn/SnO x /C composite delivered a reversible capacity of 577 mA h g −1 at a current density of 500 mA g −1 after 200 cycles. Even at a very high current density of 5 A g −1 , a specific capacity of 385 mA h g −1 was also obtained. These outstanding results suggest the Sn/SnO x /C composite as a promising anode material for high-performance lithium ion battery.
