ELECTROLYTE ADDITIVE FOR LITHIUM-ION BATRTERY

摘要

Electrolyte for a lithium-ion battery comprising at least one block copolymer, characterized in that said block copolymer comprises at least one polymeric segment A which is soluble in said electrolyte and at least one polymeric segment B having a temperature for dissolution “T” in said electrolyte, the polymeric segments A and B being present in amounts sufficient to make possible an increase in the viscosity of the electrolyte, preferably up to gelling of the electrolyte, at a temperature greater than or equal to the temperature “T”; the ionic conduction is produced by a solvent comprising the copolymer and lithium salts.
