摘　　要：以聚乙烯醇(PVA)、Nb2O5和KOH为原料,采用溶液浇铸法制备了PVA/Nb2O5复合碱性固体聚合物电解质(ASPE)。研究了Nb2O5对ASPE离子电导率(σ)和电化学稳定窗口的影响。交流阻抗和循环伏安的结果表明:加入15%Nb2O5的复合ASPE膜,室温σ为10.45 mS/cm,电化学稳定窗口为2.4 V。PVA/Nb2O5 composite alkaline solid polymer electrolyte（ASPE）was prepared via solution casting method by using polyvinyl alcohol（PVA）, Nb2O5 and KOH as raw materials. The effects of Nb2O5 on ionic conductivity （σ） and electrochemical stability window of the ASPE were investigated. The results of AC impedance and cyclic vohammetry showed that the a at room temperature of the composite ASPE membrane adding 15% Nb2O5 was 10.45 mS/em,the electrochemical stability window was 2.4 V.
