1,2,4-THIADIAZINANE-3,5-DIONE-1,1-DIOXIDE DERIVATIVES, PRODUCTION AND USE THEREOF

摘要

The invention relates to 1,2,4-thiadiazinane-1,1-dioxide derivatives, to a method for producing same, to electrolytes that contain such derivatives, and to the use of the derivatives, in particular as an electrolyte additive for lithium ion primary batteries and lithium ion secondary batteries. The aim of the invention is to improve primary batteries and secondary batteries, in particular lithium ion primary batteries and secondary batteries. For that purpose, one aspect of the invention provides a compound of general formula (I) or a salt thereof, where R1 and R2 independently of one another are F or CnF2n+1 and R3 and R4 independently of one another are C1-C10-alkyl.
