Zusammenfassung:	To provide a rechargeable lithium-ion-battery battery system including operative, electrolyte additives and electrodes for improving properties of rechargeable lithium-ion-battery systems.SOLUTION: The invention provides improved battery systems with two-additive mixtures including an electrolyte solvent that is a carbonate solvent, an organic solvent, a non-aqueous solvent, methyl acetate, or a combination of them. A positive electrode of the improved battery systems may be formed from lithium nickel manganese cobalt compounds, and a negative electrode of the improved battery system may be formed from natural or artificial graphite.SELECTED DRAWING: Figure 4E 【課題】充電式リチウムイオン電池システムの特性を改善するための、作動型電解質添加剤及び電極を含むかかる電池システムを提供する。【解決手段】カーボネート溶媒、有機溶媒、非水性溶媒、酢酸メチル、又はそれらの組み合わせである電解質溶媒を含む二添加剤混合物による改良されたバッテリーシステム。改良された電池システムの正極は、リチウムニッケルマンガンコバルト化合物から形成され得て、改良された電池システムの負極は、天然又は人造の黒鉛から形成され得る。【選択図】図４Ｅ
