本発明は電解液組成物に関する。さらに詳しくはリチウ
ム電池に適した電解液組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to electrolyte compositions. More specifically, the present invention relates to an electrolyte composition suitable for lithium batteries.
リチウムを負極活物質とする電池は高エネルギー密度が
得られ、しかも放電電圧が高いなどすぐれた特性を有し
ているが、リチウム金属の高い反応性および高い放電電
圧のため電解液組成物が不安定になりやすく、十分な電
池特性が得られない場合がある。とくに二次電池の場合
、その欠点が奢るしくなる。たとえばリチウム塩をプロ

せた電解質組成物を使用した場合、充放電時に化学変化
を起こし電池特性が低下する。Batteries using lithium as the negative electrode active material have excellent properties such as high energy density and high discharge voltage, but due to the high reactivity of lithium metal and the high discharge voltage, the electrolyte composition is insufficient. It tends to become unstable, and sufficient battery characteristics may not be obtained. Especially in the case of secondary batteries, the disadvantages become luxurious. For example, when an electrolyte composition in which a lithium salt is dissolved in propylene carbonate, tetrahydrofuran, or the like is used, chemical changes occur during charging and discharging, resulting in deterioration of battery characteristics.
