| 摘 要： | 以聚吡咯/二氧化硅(PPy/S iO2)纳米复合材料作正极,组装成锂/聚吡咯二次电池。初步探讨了集电极、隔膜厚度、正极活性材料堆密度及过充放电对电池性能的影响。结果表明,以铝箔作为集电极制备的电池,其比容量和充放电效率较以铝网作集电极为优。正极片的成型压力为20M Pa时,电池的性能最优。隔膜的薄厚对正极材料的容量影响不大,但对充放电效率的影响显著。隔膜越厚,循环效率越低;隔膜越薄,循环效率越高。 |

| Abstract: | The secondary lithium battery was made and tested by using lithium as cathod,polypyrrole-silica nanocomposite as anode.Influences of different collector,thickness of membrane,pressure on anode pellet and overcharging on the battery properties were talked about.It shows when aluminum foil as the collector,the molding pressure on anode is 20 MPa the battery has higher special capacity.The thickness of membrane has less influence on anode capacity,but bigger influence on charging-discharging efficiency.The thinner of the membrene,the better properties the battery has. |
| Keywords: | polypyrrole secondary lithium/polymer battery anode composite |
