摘要以研制高性能薄膜纸电池为目的,研究了碳纳米管加载量和球磨工艺对电池性能的影响。通过在纸电池正极材料中掺杂一定比例的经过处理的多壁碳纳米管(Multi-walledcarbonnanotubes,MWCNTs),真空包装制成薄膜纸电池;使用计算机控制精密电池测试仪,测量电池的放电性能、放电容量等电化学性能;通过改变正极材料与碳纳米管混磨时间确定球磨工艺。实验测量结果表明,在正极材料中掺杂了2%0(质量分数)碳纳米管的纸电池的放电性能最好。放电容量最大达到13.1mAh,且正极材料与碳纳米管混磨30min效果最好,放电容量达到17.8mAh。
In order to investigate the high performance film paper battery, the effect of the amount of loading carbon nanotubes and ball milling on the battery performance were studied. The film paper batteries doped with a cer- tain percentage of treated multi-walled carbon nanotubes in the cathode material were sealed in vacuum machine. The batteryrs electrochemical performance of discharge and capacity were tested by the computer controlled precision batte- ry tester. The effect of the ball milling time of the cathode material and carbon nanotubes was investigated. The re- sults demonstrate that the paper battery with 2wt~ carbon nanotubes doped in cathode material shows the best dis- charge performance and the maximum discharge capacity of 13. 1 mAh. The cathode materials of ball milling 30 mi- nutes shows the best performance, the discharge caDacitv reaches 17. 8 mAh.
