Abstract
本發明係關於一種非水電解液及使用該非水電解液而成之非水電解液二次電池,該非水電解液係於有機溶劑中溶解有鋰鹽者,其特徵在於:含有至少1種(A)通式(1)所示之化合物、與至少一種(B)於分子內具有2個以上之選自乙烯基、烯丙基及炔丙基中之基之化合物。該非水電解液較佳為(B)成分為乙烯性及乙炔性之不飽和鍵當量為150以下之化合物。通式(1)之詳細情況如本說明書所述。
Description
本發明係關於一種非水電解液二次電池,詳細而言,關於一種具有含有特定化合物之非水電解液之非水電解液二次電池。
近些年隨著可攜式電腦、手持攝錄影機、資訊終端等可攜式電子機器之普及,具有高電壓、高能量密度之非水電解液二次電池被廣泛用作電源。又,就環境問題之觀點而言,電池汽車、利用電力作為一部分動力之油電混合車之實用化正在進行。
關於非水電解液二次電池,為提高非水電解液二次電池之穩定性或電特性,揭示有非水電解液用之各種添加劑。作為此種添加劑,揭示有1,3-丙烷磺內酯(如參照專利文獻1)、碳酸乙烯基伸乙酯(如參照專利文獻2)、碳酸伸乙烯酯(如參照專利文獻3)、1,3-丙烷磺內酯、丁烷磺內酯(如參照專利文獻4)、碳酸伸乙烯酯(如參照專利文獻5)、碳酸乙烯基伸乙酯(如參照專利文獻6)等,其中,碳酸伸乙烯酯由於效果較佳,故得到廣泛使用。一般認為,該等添加劑係藉由於陽極之表面形成稱作SEI(Solid Electrolyte Interface:固體電解質膜)之穩定之覆膜,由該覆膜覆蓋陽極之表面,從而抑制電解液之還原分解。
近年來,隨著鈷、鎳等稀有金屬之價格上漲,使用錳、鐵等低價格金屬材料之正極劑的使用及開發得以急速發展。其中,含有錳之過渡金屬氧化物含鋰鹽因於非水電解液二次電池之容量、輸出方面性能優異,故為受到關注之正極劑之一。然而,可知於使用含有錳之過
渡金屬氧化物含鋰鹽作為正極活性物質之非水電解液二次電池中,錳易自正極溶出,該溶出之錳導致發生副反應,電池產生劣化而引起容量、輸出之下降。
作為抑制自正極之錳溶出之方法,揭示有非水電解液用之各種添加劑。作為此種添加劑,揭示有二磺酸酯等(如參照專利文獻7),但要求進一步之改良。

專利文獻2:日本專利特開平4-87156號公報

專利文獻4:日本專利特開平10-50342號公報
專利文獻5:US5626981
專利文獻6:US6919145
因此,本發明之目的在於針對使用含有過渡金屬與鋰之正極之非水電解液二次電池,實現抑制自正極溶出之過渡金屬所致之非水電解液二次電池之劣化,即使經過高溫保存或高溫下之充放電而亦能夠維持較小之內部電阻與較高之電容。
本發明者等人經努力研究發現,藉由使用含有特定結構之化合物之非水電解液而能夠達成上述目的,完成本發明。
本發明提供一種非水電解液,其係於有機溶劑中溶解有鋰鹽者,其特徵在於:含有至少一種(A)下述通式(1)所表示之化合物、與
至少一種(B)分子內具有2個以上之選自乙烯基、烯丙基及炔丙基中之基之化合物。
(式中,R1表示n價之碳原子數2~6之不飽和烴或碳原子數6~12之伸芳基,R2、R3及R4分別獨立地表示碳原子數1~20之飽和脂肪族烴或碳原子數6~20之芳香族烴基,n表示2~6之整數)。
本發明提供一種使用上述非水電解液而成之非水電解液二次電池。
依據本發明,可提供一種非水電解液二次電池,其藉由使用含有特定結構之化合物之非水電解液,而防止過量充電的能力優異,經過充放電後亦能夠維持較小之內部電阻與高電容。

將所得之圓盤狀正極與圓盤狀負極隔著厚度25μm之聚乙烯製微多孔膜保持於殼體內。其後,向殼體內注入上述製備之各非水電解液,將殼體密閉、密封,而製作實施例及比較例之非水電解液二次電池(20mm、厚度3.2mm之硬幣型)。
就實施例及比較例之鋰二次電池,依據下述試驗法進行評價。
將該等試驗結果示於下述[表1]及[表2]。
[放電容量比試驗方法(初期特性)]
將鋰二次電池放入至20℃之恆溫槽內,以充電電流0.3mA/cm2(相當於0.2C之電流值)進行定電流定電壓充電直至達到4.2V,以放電電流0.3mA/cm2(相當於0.2C之電流值)進行定電流放電直至達到3.0V,進行5次該操作。其後,以充電電流0.3mA/cm2進行定電流定電壓充電直至達到4.2V,以放電電流0.3mA/cm2進行定電流放電直至達到3.0V。將該第6次所測得之放電容量設為電池之初期放電容量,將僅添加1份(A)成分之情形時之初期放電容量設為100,如下式所示般算出放電容量比(%)。再者,[表1]表示使用A-1作為(A)成分之情形之結果,[表2]表示使用A-2作為(A)成分之情形之結果。
放電容量比(%)=[(初期放電容量)/(僅添加1份(A)成分之情形時之初期放電容量)〕×100
[放電容量比試驗法(循環特性)]
將初期特性試驗後之鋰二次電池放入至60℃之恆溫槽內,以充電電流1.5mA/cm2(相當於1C之電流值,1C係於1小時內放出電池容量時之電流值)進行定電流充電直至達到4.2V,以放電電流1.5mA/cm2進行定電流放電直至達到3.0V,重複進行上述操作150次。將該第150次之放電容量設為循環試驗後之放電容量,將僅添加1份(A)成分之情形時之循環試驗後之放電容量設為100,如下式所示般求出該情形時之循環試驗後之放電容量之比率作為放電容量維持率(%)。再者,[表1]表示使用A-1作為(A)成分之情形之結果,[表2]表示使用A-2作為(A)成分之情形之結果。
循環特性(%)=[(循環試驗後之放電容量)/(僅添加1份(A)成分之情形時之循環試驗後之放電容量)〕×100
不飽和鍵當量:162.2
依據上述結果可知,本發明之非水電解液所使用之以(A)成分及(B)成分表示之化合物不會使電池特性(放電容量)降低,能夠抑制過量充電時之電壓上升。
