Title:
LITHIUM ION BATTERY
Document Type and Number:
Japanese Patent JP2018005973
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a battery having a life performance of a secondary battery, and to improve the output of such a battery by forming a low-resistance coating.SOLUTION: An electrolyte solution for a lithium ion secondary battery comprises: vinylene carbonate; and an additive agent represented by the formula 1. In the electrolyte solution, a total amount (VC+additive agent) of the vinylene carbonate and the additive agent represented by the formula 1 to a weight of the electrolyte solution falls in a range given by 0.2 wt%<(VC+additive agent)<2.0 wt%. The ratio (VC/(VC+additive agent)) of an amount of the vinylene carbonate to the total amount of the vinylene carbonate and the additive agent represented by the formula 1 is in a range given by 0.1<(VC/(VC+additive agent))<0.75.SELECTED DRAWING: Figure 1
