Abstract:
Lithium ion rechargeable batteries having high energy densities are widely used for portable electronic devices, and they are still the subject of intensive investigation because of the possibility on a wide range of future applications. Tin oxide (SnO2) has been studied as a promising alternativeto the commercially used graphite anode material because of its much higher theoretical specific capacity, which arises from different electrochemical reactions. Here, we report a method for synthesis SnO2 as an anode material in Li-ion batteries. The performance of SnO2 electrode as an anode in lithium secondary battery was evaluated using conventional electrochemical analysis such as cyclic voltammetry, charge discharge profile and electrochemical impedance spectroscopy (EIS).SnO2 nanoparticles coating was prepared by a simple wet chemical method. The product exhibited an excellent lithium intercalation/deintercalation performance as anode materials for lithium-ion batteries. Our material displayed large specific capacity at high current density
