Title:
ION-CONDUCTIVE MATERIAL AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2007/023920
Kind Code:
A1
Abstract:
Disclosed is an ion-conductive material which comprises an ionic solution and can achieve a high level of safety. Also disclosed is an electrochemical device using the material. Further disclosed is a method for production of the electrochemical device. An ion-conductive material comprising an ionic solution which satisfies the following requirements: the solution comprises at least two types of anions each of which has an electron-attracting group bound to the central atom having a non-covalent electron pair; and the solution shows the height of the maximum exothermic peak in a heat flow of 2 W/g or less as determined by DSC (measurement temperature range: room temperature to 500˚C, temperature ramping rate: 2˚C/min). Preferably, the ionic solution in the ion-conductive material shows the total calorific value of 1000 J/g or less as measured by DSC.
