<P>PROBLEM TO BE SOLVED: To provide electrolytic solution for a lithium-ion secondary battery which is superior in cycle lifetime characteristics and high temperature preservation stability, and which prevents fall of low temperature discharge capacity, and the lithium-ion secondary battery containing this. <P>SOLUTION: The lithium-ion secondary battery to which the electrolytic solution is applied has effects of generating a stable SEI coating in the initial charging, improving cycle lifetime characteristics, and of suppressing reduction of the low temperature discharge capacity and swelling when left at high temperatures. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
