摘　　要：以掺杂碳纳米管的氯化亚铜为正极材料,以镁为负极材料,使用滤纸为隔膜,将正极材料涂覆于浆层纸上,石墨片作为正极的集流体,制成液体激活镁-氯化亚铜纸电池,研究了碳纳米管改性薄膜镁电池。使用计算机控制精密电池测试仪测试并比较了不同活化液激活时电池的放电性能,研究结果显示,以绿豆汁为电池激活剂,镁-氯化亚铜电池具有更好的性能。在0.3 m A恒流放电测试时,镁-氯化亚铜电池比容量达到134 m Ah/g,放电时间达到27 h。With CuCl doped with carbon nanotubes as cathode materials, metallic magnesium as anode ones and filter paper as separator, cathode materials were painted on coated paper and the graphite flake as a cathode current collector, then magnesium-CuCI paper battery activated by liquids was prepared. The electrochemical properties of magnesium-CuCl batteries modified by carbon nanotubes were investigated. The six different types of liquid were used to activate the paper battery. A battery tester was used to measure the battery＇s electrochemical performance. The results show that magnesium-CuCl battery activated by green bean soup achieves a better overall performance. The specific capacity of the paper battery reaches 134 mAh/g and the discharge time reaches 27 h when charging and discharging at 0.3 mA constant current.
