Abstract

Disclosed herein is a three-electrode-system-type electrode potential measurement device for measuring the electrode potential of a cylindrical battery cell in which a beading portion is in a divided condition, the beading portion provided between a top cap assembly and a battery case, a first electrode terminal of the cylindrical battery cell located at the top cap assembly, and a second electrode terminal of the cylindrical battery cell located at the battery case, the electrode potential measurement device including a working electrode connection unit connected to one of the first electrode terminal or the second electrode terminal; a counter electrode connection unit connected to the other of the first electrode terminal or the second electrode terminal; a reference electrode connection unit connected to a reference electrode; a measurement unit connected to the working electrode connection unit; and a short-circuit prevention member located between the top cap assembly and the battery case.
