Abstract: Anew anode material for lithium ion batteries, MgSnO3, was prepared through the pyrolysis of MgSn(OH)6.The product was characterized by XRD, TEMAnd electrochemical measurements.The results show that it is amorphous and the size is about 70-160 nm.The reversible capacity of the MgSnO3electrode was 635mA·h·g-1in the first cycle and was about 500mA·h·g-1in the 20th cycle.

Key words: Anode material, Lithium ion batteries, Tin-magnesium composite oxide
