Abstract
Official abstract text for this publication.
Disclosed is an electrolyte solution used for a lithium secondary battery having high capacity, less undergoing aging deterioration of capacity, and also excellent in life characteristic. The electrolyte solution used for a lithium secondary battery contains a compound having a trivalent or higher boron formed by incorporation of a boroxine compound represented by (RO)3(BO)3 in which R(s) each represent independently an organic group of 1 to 6 carbon atoms and LiPF6, and a non-aqueous solvent.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrolyte solution used for a lithium secondary battery containing a compound having trivalent and higher boron formed by incorporation of a boroxine compound represented by (RO) 3 (BO) 3 in which R(s) each represent CH(CH 3 ) 2 and LiPF 6 , and a non-aqueous solvent, wherein the amount of the boroxine compound is 0.1% by weight to 1.0% by weight based on the total amount of LiPF 6 and the non-aqueous solvent, and wherein the electrolyte solution for the lithium secondary battery further contains vinylene carbonate. 2. A lithium secondary battery having a positive electrode and a negative electrode capable of occluding and releasing lithium ions and a separator, and using the electrolyte solution used for the lithium secondary battery according to claim 1 as an electrolyte solution.
