Tin‐based oxide Li 2 SnO 3 has been synthesized by a hydrothermal route as negative material for lithium‐ion batteries. The microstructure and electrochemical properties of the as‐synthesized materials were investigated by some characterizations means and electrochemical measurements. The as‐synthesized Li 2 SnO 3 is a porous rod, which is composed of many uniform and regular nano‐flakes with a size of 50–60 nm. Li 2 SnO 3 also displays an electrochemical performance with high capacity and good cycling stability (510.2 mAh g −1 after 50 cycles at a current density of 60 mA g −1 between 0.0 V and 2.0 V verusus Li/Li + ).
