Zusammenfassung:A new class of low flammability cosolvents comprising saturated C1-C8 alkyl (meth)acrylate oligomers having a molecular weight in the range of from about 160 to 1000 g/mol are disclosed for use in nonaqueous electrolytes for electrochemical cells. A novel process for preparing saturated meth(acrylic) oligomeric electrolyte cosolvents is also disclosed. Secondary electrochemical cells employing an anode, a cathode, and a non-aqueous electrolyte solution comprising these new cosolvents are also disclosed.
