单壁碳纳米管内1,4-萘琨电池电极材料性能的研究

Study on Properties of 1,4-naphthoquinone Encapsulated in Single-walled Carbon Nanotubes As Electrode Materials for Batteries

1,4-萘琨具有两个羰基结构,其理论容量高达357 m Ah/g。然而,1,4-萘琨同时存在导电性较差,易溶解在电解液中等问题,限制了其应用。研究了将单壁碳纳米管作为封装材料,将1,4-萘琨分子封装在单壁碳纳米管内部,来解决上述问题。研究发现,封装在单壁碳纳米管内部的1,4-萘琨趋于稳定,可制备出可应用于水系电解液电池的电极材料。

1,4-naphthoquinone has two carbonyl groups and its theoretical capacity is up to 357 m Ah/g. However,the poor conductivity and high dissolubility limit its application. In this study,single-walled carbon nanotubes were used as packaging materials to encapsulate 1,4-naphthoquinone molecules in order to solve the above problems. It was found that the 1,4-naphthoquinone encapsulated in single-walled carbon nanotubes tended to be stable,and the electrode materials for aqueous electrolyte batteries were successfully prepared.
