取實施例8-1~8-4與比較例3-1~3-4之共聚高分子乾燥後樣品2~5 mg,且DCS測定範圍為-20~150℃,並以每分鐘10℃為升溫條件,觀測其玻璃轉移溫度,其結果係如圖4~圖10所示。
如圖4~圖10所示,由實施例8-1~8-4與比較例3-1~3-3比較可得,本案之實施例8-1~8-4相較於比較例3-1~3-3具有較低的玻璃轉移溫度,本案實施例8-1~8-4的玻璃轉移溫度皆在40~80℃之間,但相較之下,比較例3-1~3-3的玻璃轉移溫度皆在100~120℃之間,代表本案之實施例8-1~8-4具有較佳的可撓性與加工性,因此在製作極片時可具較佳的輾壓密度與捲繞性。
綜合上述實施例及比較例之測試結果可理解,本發明之能量儲存裝置係於陽極、陰極及隔離層中之至少一者係包含一共聚高分子,且該共聚高分子係為丙烯腈與乙酸乙烯酯經聚合反應後所形成之共聚物或其衍生物。藉此,可使應用該共聚高分子之能量儲存裝置具有較佳的充放電性質,可有效地延長能量儲存裝置的效率及壽命。
實施例8-1~8-4之共聚高分子藉由包含衍生自乙酸乙烯酯的單體,可使其具有較低的玻璃轉移溫度,且具有較佳的可撓性與加工性。相較之下,比較例3-1~3-3之共聚高分子由於未包含衍生自乙酸乙烯酯的單體,使其具有較高的玻璃轉移溫度,且可撓性與加工性不佳。
本發明在上文中已以較佳實施例揭露,然熟習本項技術者應理解的是,該實施例僅用於描繪本發明,而不應解讀為限制本發明之範圍。應注意的是,舉凡與該實施例等效之變化與置換,均應設為涵蓋於本發明之範疇內。因此,本發明之保護範圍當以申請專利範圍所界定者為準。
