The gravimetric and volumetric energy density of Li-PAn battery increase with increasing of bulk density of PAn. But the too high bulk density decreases its gravimetric energy density because the PAn electrode with high bulk density has smaller and more uniformly distributed pores observed by SEM. As the PAn electrode with same bulk density, the smaller the thickness, the greater the gravimetric energy density. For the electrolyte of PC/LiClO4,at concentration of 1. 0 mol/L the battery has a maximum gravimetric...

The gravimetric and volumetric energy density of Li-PAn battery increase with increasing of bulk density of PAn. But the too high bulk density decreases its gravimetric energy density because the PAn electrode with high bulk density has smaller and more uniformly distributed pores observed by SEM. As the PAn electrode with same bulk density, the smaller the thickness, the greater the gravimetric energy density. For the electrolyte of PC/LiClO4,at concentration of 1. 0 mol/L the battery has a maximum gravimetric energy density. The mixed electrolyte of PC and DME (1:1) has improved the battery performance and high rate discharge capability. In respect to the same concentration,gravimetric energy density of battery with PC is tested to be 68% that of the mixed one.

采用混合溶剂作电解液和对聚苯胺(PAn)电极加压,变换厚度以及扫描电子显微镜观察的方法,探讨了PAn的堆积密度和电解液与电池比能量的关系.实验结果表明,用加压的方法提高PAn的堆积密度,能有效地提高电池的质量比能量和体积比能量.但当堆积密度过高时,其质量比能量反而会随之下降.由电镜的观察知道,堆积密度较高的PAn电极,其孔隙较小,孔隙的分布也较均匀.对于堆积密度相同的PAn电极,厚度越小,其质量比能量就越大.另外,在碳酸丙烯酯(PC)加高氨酸锂(LiCl0_4)的电解液中,浓度为1.0mol/L的电池的质量比能量为一个极大值.浓度相同的条件下,在PC中加入等体积二甲氧基乙烷(DME)的混合电解液的电池与以PC为单一电解液电池相比,后者质量比能量的极大值只相当于前者的68%,后者的大电流放电性能也比前者的差很多.
