LITHIUM SECONDARY BATTERY SEPARATOR, LITHIUM SECONDARY BATTERY FOR WHICH LITHIUM SECONDARY BATTERY SEPARATOR IS ADOPTED, AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a lithium secondary battery separator; a lithium secondary battery for which a lithium secondary battery separator is adopted; and a method for manufacturing a lithium secondary battery.SOLUTION: A lithium secondary battery separator comprises a porous base material and a first coating layer formed on one face of the porous base material. In the lithium secondary battery separator, the first coating layer includes (meth)acrylic acid ester based polymer particles of which the glass transition temperature is 10 to 60°C. Also, means for solution is a lithium secondary battery for which the lithium secondary battery separator is adopted. In a method for manufacturing the lithium secondary battery, the first coating layer is arranged so as to face a positive electrode.SELECTED DRAWING: Figure 2
