ELECTROLYTES FOR LITHIUM ION BATTERIES AND THEIR FABRICATION METHODS

摘要

The present invention discloses electrolytes for lithium ion batteries. Said electrolytes comprise of lithium salts, organic solvents and additives. In particular, the additives are comprised of halogeno-benzene and/or its homologs, the S=O bond compounds, biphenyl and/or its homologs, phenylcyclohexane and/or its homologs, teraklylbenzenes, and di-cycladipate and/or its homologs. Lithium ion batteries using said electrolytes exhibit improved overcharging safety properties, high temperature storage stability properties and cycle life properties simultaneously.
