【摘要】 <正> 自MacDiarmid等将聚乙炔（PA）做为二次电池的电极材料以来,其电化学特性和行为引起了人们的极大兴趣.随后的研究表明,p-型PA[（CH）^y+Ay^-]_x在电解液中不稳定,用ClO₄^-掺杂的PA充放循环时有降解发生.n-型PA[My⁺（CH）^y-]_x（y≤0.10）在THF/LiClO₄电解质中较稳定,电化学还原完全可逆,目前已实现1100次充放循环.因此,它既可做电池的正极材料（碱金属为负极）,又可做负极材料（TiS₂为正极）.我们发现更多还原

【Abstract】 The discharge properties of the cell consisted of Li/1mol/dm³ LiClO₄ + THF/PA/carbonfibre composite film have been investigated by galvanostatic method.When it was dischargedat a small constant current the cell showed energy density and capacity up to 726Wh/kgand 624Ah/kg respectively. Increasing PA content in the composite can increase the capa-city of the cell, but deteriorate other properties. The rate of self-discharge in a year wasbelow 6%.更多还原
