Title: (EN) NOVEL BATTERY SYSTEMS BASED ON TWO-ADDITIVE ELECTROLYTE SYSTEMS
Abstract: front page image
(EN)

Improved battery systems have been developed for lithium-ion based batteries. The improved battery systems consist of two-additive mixtures in an electrolyte solvent that is a carbonate solvent, an organic solvent, a non-aqueous solvent, and/or methyl acetate. The positive electrode of the improved battery systems may be formed from lithium nickel manganese cobalt compounds, and the negative electrode of the improved battery system may be formed from natural or artificial graphite.
