Title:
リチウム二次電池用電解液及びこれを含むリチウム二次電池
Document Type and Number:
Japanese Patent JP7376711
Kind Code:
B2
Abstract:
Disclosed are an electrolyte solution for the lithium secondary battery, which can improve the performance of the battery, by combining a highly reactive solvent and lithium salt which can increase the capacity of the battery, and a highly stable solvent and lithium salt which can increase the lifetime of the battery, and a lithium secondary battery comprising the same. The electrolyte solution for the lithium secondary battery comprises a first solvent comprising a heterocyclic compound containing one or more double bonds and at the same time, containing any one of an oxygen atom and a sulfur atom; a second solvent comprising at least one of an ether-based compound, an ester-based compound, an amide-based compound, and a carbonate-based compound; lithium salt; lanthanum nitrate; and an additive comprising lithium nitrate.
