Abstract
Abstract Graphene supported Li2SiO3/Li2SnO3 (LSO-LSnO-GE) composite has been prepared through a hydrothermal method. The microstructure and electrochemical performance of LSO-LSnO-GE have been investigated by a variety of means. When used as an anode material for lithium ion battery, the initial specific discapacity of LSO-LSnO-GE composite is 1016.5 mAh/g at the current density of 150 mA/g, and its specific capacity is 440.8 mAh/g after 200 cycles. The improvement of lithium storage performance of LSO-LSnO-GE composite can be explained the synergistic effect of that LSnO, LSO and graphene. In addition, the LSO-LSnO-GE shows the initial discharge capacity of 263.1 mAh/g at the current density of 30 mA/g in LSO-LSnO-GE/LiMn2O4 full cell, which could indicate that LSO-LSnO-GE may be used as an anode material for lithium ion full cells.
