Tin based anode materials have been regarded as one of the most promising alternative to the conventional graphite for lithium ion batteries due to the high theoretical capacity (781 mAh/g) and the low potential of lithium ion insertion and desertion. However, the large volume changes and the formation of electrochemical inactive Li2O during charging and discharging processes result in the poor cycle performance and loss of capacity. In this research, the desired tin oxide is deposited within the pores in polycarbonate template. To remove the polycarbonate template and embed the tin oxide in the polycarbonate template, heat-treatment at 500 ℃ in argon was conducted. The synthesized materials were tested as an anode materials for high-rate and high-capacity lithium ion batteries. |
