Description
本発明によれば、保存後の電池の正極抵抗を低減できる電池用非水電解液及びリチウム二次電池を提供することができる。 According to the present invention, it is the child provides a positive electrode resistance can be reduced non-aqueous electrolyte and a lithium secondary battery cell of the battery after storage.
ニトリル化合物としては、本発明の効果がより効果的に奏される点で、スクシノニトリル、アジポニトリル、プロピオニトリルが特に好ましい。 As the nitrile compound, succinonitrile , adiponitrile , and propionitrile are particularly preferable in that the effects of the present invention are more effectively exhibited.
以上で説明した添加剤Ｂは、本発明の効果がより効果的に奏される点で、スクシノニトリル、アジポニトリル、プロピオニトリル、１、３−ジオキサン、及び２−メチルテトラヒドロフランからなる群から選択される少なくとも１種を含むことが特に好ましい。 Additive B described above is selected from the group consisting of succinonitrile, adiponitrile, propionitrile, 1,3-dioxane, and 2-methyltetrahydrofuran in that the effects of the present invention are more effectively achieved. It is particularly preferable to include at least one of the above.
＜非水電解液の調製＞
非水溶媒としてエチレンカーボネート（ＥＣ）とジメチルカーボネート（ＤＭＣ）とメチルエチルカーボネート（ＥＭＣ）とをそれぞれ３０：３５：３５（質量比）の割合で混合し、混合溶媒を得た。
得られた混合溶媒中に、電解質であるＬｉＰＦ６を、最終的に得られる非水電解液中における電解質濃度が１モル／リットルとなるように溶解させた。
上記で得られた溶液に対して、添加剤Ａ（環状硫酸エステル化合物）としての上記例示化合物Ａ−１（添加量０．５ｗｔ％）、及び、添加剤Ｂとしてのアジポニトリル（添加量０．２ｗｔ％）をそれぞれ添加し、非水電解液を得た。
<Preparation of non-aqueous electrolyte>
As a non-aqueous solvent, ethylene carbonate (EC), dimethyl carbonate (DMC), and methyl ethyl carbonate (EMC) were mixed at a ratio of 30:35:35 (mass ratio), respectively, to obtain a mixed solvent.
In the obtained mixed solvent, LiPF 6 as an electrolyte was dissolved so that the electrolyte concentration in the finally obtained nonaqueous electrolytic solution was 1 mol / liter.
With respect to the solution obtained above, the exemplified compound A-1 (addition amount 0.5 wt%) as additive A (cyclic sulfate ester compound) and adiponitrile as additive B (addition amount 0.2) wt%) was added to obtain a non-aqueous electrolyte.
