摘要
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)<sup>y+</sup>Ay<sup>-</sup>]<sub>x</sub>在电解液中不稳定,用ClO<sub>4</sub><sup>-</sup>掺杂的PA充放循环时有降解发生.n-型PA[My<sup>+</sup>(CH)<sup>y-</sup>]<sub>x</sub>(y≤0.10)在THF/LiClO<sub>4</sub>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(TiS<sub>2</sub>为正极).
The discharge properties of the cell consisted of Li/1mol/dm^3 LiClO_4 + 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%.
