Tin based anodes have been regarded as one of the most promising candidates for lithium ion batteries due to the high theoretical capacity (781 mAh/g) and the low potential of lithium ion intercalation and deintercalation. However, the large volume changes and the formation of electrochemical inactive Li2O during the charging and discharging processes result in the loss of capacity and poor cycle performance. 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 air and in argon, respectively was conducted. The synthesized materials were tested as an anode for high-rate and high-capacity lithium ion batteries. |
