The invention relates to the use of compounds according to general formula (1), in particular 1,4,2-dioxoazol-5-on-derivatives, as additives in electrolytes for electrochemical energy sources such as lithium-ion-batteries, and compounds containing electrolytes according to general formula (1), in particular 1,4,2-dioxoazol-5-on-derivatives.

Electrolyte-additive for lithium-ion battery systems

An electrolyte for a lithium-ion battery which includes lithium hexafluorophosphate and lithium 2-pentafluoroethoxy-1,1,2,2-tetrafluoroethanesulfonate. A lithium-ion battery which includes an electrolyte containing lithium hexafluorophosphate and lithium 2-pentafluoroethoxy-1,1,2,2-tetrafluoroethanesulfonate. A motor vehicle which uses a lithium-ion battery having electrolytes containing lithium hexafluorophosphate and lithium 2-pentafluoroethoxy-1,1,2,2-tetrafluoroethanesulfonate. The electrolyte can increase the service life of the lithium-ion battery.

Electrolyte for lithium based energy accumulators

An alkali metal-based energy storage system, having at least one composite electrode containing an active material, and an electrolyte containing a lithium salt dissolved in an aprotic organic solvent, an ionic fluid and/or a polymer matrix. The electrolyte further contains an additive selected from a cation or a compound of a metal selected from Mg, Al, Cu and/or Cr. The metal selected from Mg, Al, Cu and/or Cr is applied onto the active material and/or the active material of the composite electrode is partially replaced by the metal selected from Mg, Al, Cu and/or Cr in the form of a metal powder or a metal salt.
