Description
前記非水系溶媒は、線形又は環状のカーボネート系溶媒か、ラクトン系溶媒であり、リチウム塩及び二次電池用電解液添加剤に対する溶解度が高いものが好ましい。例えば、該非水系溶媒は、ジエチルカーボネート（ｄｉｅｔｈｙｌ ｃａｒｂｏｎａｔｅ）、エチルメチルカーボネート（ｅｔｈｙｌ ｍｅｔｈｙｌ ｃａｒｂｏｎａｔｅ）、ジメチルカーボネート（ｄｉｍｅｔｈｙｌ ｃａｒｂｏｎａｔｅ）、ジプロピルカーボネート（ｄｉｐｒｏｐｙｌ ｃａｒｂｏｎａｔｅ）、メチルプロピルカーボネート（ｍｅｔｈｙｌ ｐｒｏｐｙｌ ｃａｒｂｏｎａｔｅ）、エチルプロピルカーボネート（ｅｔｈｙｌ ｐｒｏｐｙｌ ｃａｒｂｏｎａｔｅ）などの線形カーボネート系溶媒と、エチレンカーボネート（ｅｔｈｙｌｅｎｅ ｃａｒｂｏｎａｔｅ）、プロピレンカーボネート（ｐｒｏｐｙｌｅｎｅ ｃａｒｂｏｎａｔｅ）、ブチレンカーボネート（ｂｕｔｙｌｅｎｅ ｃａｒｂｏｎａｔｅ）、フルオロエチレンカーボネート（ｆｌｕｏｒｏｅｔｈｙｌｅｎｅ ｃａｒｂｏｎａｔｅ）などの環状カーボネート系溶媒と、γ−ブチロラクトン（ｇａｍｍａ−ｂｕｔｙｒｏｌａｃｔｏｎｅ）などのラクトン系溶媒とからなる群より選択される、１種の溶媒又は２種以上の混合溶媒であり得る。 The non-aqueous solvent is preferably a linear or cyclic carbonate solvent or a lactone solvent, and preferably has high solubility in lithium salt and electrolyte additive for secondary batteries. For example, the non-aqueous solvent may be diethyl carbonate, ethyl methyl carbonate, dimethyl carbonate, dipropyl carbonate, methyl propyl carbonate, ethyl propyl carbonate (ethyl propyl carbonate) which linear carbonate-based solvents include ethylene carbonate (ethylene carbonate), propylene carbonate (propylene carbonate), butylene carbonate (butylene carbonate), fluoroethylene carbonate Ne It may be one solvent or a mixture of two or more solvents selected from the group consisting of cyclic carbonate solvents such as fluoroethylene carbonate and lactone solvents such as gamma-butyrolactone. .
