聚并苯二次电池的研究

聚乙炔在电解质中能进行电化学可逆的离子掺杂和脱掺杂,以聚乙炔膜作为电极的活性物质,用PVDF、LiClO_4-PC薄膜作为电解质,制作了可充式全塑电池,但由于聚乙炔在空气中稳定性差,电池的放电性能还不理想,目前,除聚苯胺电池在日本已有商品外,其它几种聚合物电池还都处于实验室研究开发阶段,用聚并苯半导体材料分别为正负极制做的全塑电池,自放电小,循环寿命可达3000次,是有实用价值的聚合物二次电池之一,前文对酚醛树脂的热解过程、产物结构、电学性质及导电机制等进行了研究,本文研究了用聚并苯材料做锂二次电池的正极活性物质、高氯酸锂(溶解在碳酸丙烯酯中,1 mol/L)为电解质的二次电池性能。

Studies on Polymer Secondary Battery Employing Polyacenic Semiconductor

Polymer secondary batteries employing polyacenic semiconductor (PAS) as the cathode which is prepared from phenol-formaldehyde resin by pyrolytic process have been assembled,by using Li as an anode and the solution of I mol/L LiClO4 in PC as the electrolyte. These batteries show an excellent reversibility for electrochemical doping-undoping process and the charge-discharge cycles under 1 mAh have reached 300 times and the energy density is 162 Wh/kg. We believe that the PAS battery promises to be applied to conductive polymers in practice.
