摘要： Lithium heteropoly blue(Li5PW10ⅥW2ⅤO40) was used as a non-aqueous electrolyte in the polyacenic semiconductor (PAS)-Li secondary battery instead of LiClO4. The properties of the PAS-Li secondary battery, especially the effect of Li5PW10ⅥW2ⅤO40 on the capacity, the cycle property and the self-discharging of the battery have been investigated. The results indicate that not only Li5PW10ⅥW2ⅤO40 can overcome the disadvantages of LiClO4, which is apt to explode when heated or rammed, but also the PAS-Li secondary battery assembled with the novel electrolyte has a larger capacity and smaller self-discharging than that assembled with LiClO4. Therefore, it is believed that lithium heteropoly blue is a better and novel electrolyte for the PAS secondary battery and exhibits significant and practical application.
