Title:
ION CONDUCTOR FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY USING IT
Document Type and Number:
Japanese Patent JPH1167268
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ion conductor capable of enhancing charge/discharge characteristics while high voltage and high energy density of a battery are kept by constituting with at least an electrolyte and an additive, and using at least one kind of amine carbonates as the additive. SOLUTION: An additive contained in an ion conductor is at least one kind of amine carbonates represented by the formula. In the formula, R<1> and R<2> may be the same or different, and represent a hydrogen atom, a lower alkyl group which may have a substituting group, and a phenyl group which may have a substituting group, and X represents a cation. The amine carbonate is preferable to be a carbonate of primary-, secondary-, tertiary-amino alcohol, and practically, carbonates of 2-amino-1-butanol, isopropanol, and the like are listed. The additive is contained 1-2 vol.% in the lithium ion conductor.
