<P>PROBLEM TO BE SOLVED: To provide a lithium secondary battery and a separator or the like for the lithium secondary battery excellent in ionic conductivity or the like. <P>SOLUTION: A separator composition for the lithium secondary battery contains a plasticizer of a boiling point of 240 to 300°C, a polymer, a filler and a solvent. The separator for the lithium secondary battery is obtained by coating and drying the separator composition for the lithium secondary battery on a base material, or, casting and drying it on another support body and then peeling it off from the support body. The lithium secondary battery is obtained by integrating the separator for the lithium secondary battery and a specific electrode for the lithium secondary battery and, afterwards, by removing the plasticizer of a boiling point of 240 to 300°C, and it contains an electrolyte solution. <P>COPYRIGHT: (C)2004,JPO |
