Title: (EN) NOVEL BATTERY SYSTEMS BASED ON TWO-ADDITIVE ELECTROLYTE SYSTEMS INCLUDING 1,2,6-OXODITHIANE-2,2,6,6-TETRAOXIDE
Abstract: front page image
(EN)

Improved battery systems with two-additive mixtures including in an electrolyte solvent that is a carbonate solvent, an organic solvent, a non-aqueous solvent, methyl acetate, or a combination of them. 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.
