Cap :靜電容量 tan (5 :介電損耗之正切值 △ Cap :靜電容量變化率 由表1可明確得知,相較於比較例,實施例之電解電 容器用電解液的點火電壓較高,比阻抗也較低。而且,由 表2可以得知,相較於比較例,使用此電解液之1 0 0 W V電解 電容器的t a η 5較低,高溫壽命特性也較佳。另外,取代環 丁颯而改用1,3 -二乙基咪唑酮也可以得到同樣的結果。 而且,使用已進行磷酸處理之電極箔作為陽極電極箔 或陰極電極箔的情形,進一步提高了高溫壽命特性,還 有,若於電解液中添加磷化合物,更加提高了高溫壽命特 性。另外,於由異丁烯、異戊二烯與二乙烯基苯之共聚物 所形成的丁基橡膠聚合物中,添加過氧化物作為架橋劑的 過氧化物部分架橋丁基橡膠作為封口物使用的情形,也改 善了液漏效果。
第18頁 1313882 五、發明說明(11) 產業上利用性 根據此發明,因為使用含有四氟化鋁鹽、及高沸點溶 劑的電解電容器用電解液,能夠提供一種具有低阻抗特 性、高耐電壓特性、與良好的高溫壽命特性之電解電容 器。
