Abstract

The present invention provides a conductive protective layer-forming paste for current collector laminates which can be used even for high voltage designs to protect current collectors from corroding without loss of cell characteristics, and a current collector laminate, an electrode laminate, and nonaqueous secondary cells (e.g. a lithium secondary cell, an electric double layer capacitor) that include a conductive protective layer formed therefrom. The paste for forming conductive protective layers for current collector protection includes: polytetrafluoroethylene; and a conductive filler (b). The current collector laminate includes: a conductive protective layer (A); and a current collector (B), the conductive protective layer (A) being formed by coating the paste for forming conductive protective layers onto the current collector (B).
