NEGATIVE POLE PROTECTING FILM COMPOSITE FOR LITHIUM METAL BATTERY, NEGATIVE POLE MANUFACTURED USING IT FOR LITHIUM METAL BATTERY, AND LITHIUM METAL BATTERY

摘要

PPROBLEM TO BE SOLVED: To provide a negative pole protecting film composite for a lithium metal battery, which suppresses an accompanying reaction between a negative pole and electrolyte and improves cycle life property, to provide the negative pole manufactured using the composite for the lithium metal battery, and to provide the lithium metal battery. PSOLUTION: The negative pole protecting film composite for the lithium metal battery includes a multi-functional monomer containing two or more double bonds which have capability of bridge reaction, a plasticizer containing ether group, and compounds more than one kind chosen from alkali metal salt. A protective film 2b which is formed on the negative pole 2 using the negative pole protecting film composite lowers reactivity of the negative pole 2, stabilizes its surface and improves the life of the lithium metal battery.
