摘要: 用经γ射线辐照交联的PEO作为固体电解质,研究了聚苯胺(PAn)固态锂电他的电化学特性。实验发现通过γ-辐射交联后的PEO电解质,室温电导率可达10-4S/cm以上,并具有较好的机械强度。经过68次的充放电循环实验、电池放电容量仍维持在60mAh/gPAn以上。该电池交流阻抗分析表明,界面Li/PEO的阻抗远大于界面PEO/PAn的阻抗。循坏伏安结果显示了聚苯胺具有良好的氧化还原可逆性。

Abstract: The electrochemical perforrnances of all- solid state lithium battery using polyaniline positive electrode and γ-ray crosslinked PEO electrolyte containing LiClO4/PC solution have been studied.It showed that the ambient temperature conductivity of PEO was over 10-4S/cm as a result of γ-ray irradiation. The capacity of over 60mAh/g and the charge-discharge life of over 68 cycles were achieved for the polyaniline lithium battery. The acimpedance at the Li/PEO interface was much greater than that at PEO/PAn. The result of cyclic voltammetry showed good reversibility of the polyaniline electrode in the lithium battery.
