(57) [Summary] [Purpose] To provide a rapid electrical analysis method using battery cells. [Structure] Using a working electrode containing a sample substance, a counter electrode containing a battery active material, and a battery cell containing a substance capable of ion flow in a portion adjacent to both electrodes, an external voltage is applied between both electrodes. A method for electroanalyzing a sample substance, which comprises quantifying the sample substance by measuring at least one kind or more of a voltage, a current, or an electric quantity generated between both electrodes without applying a voltage. [Effect] Without adding electrical energy from outside The sample substance can be quantified quickly and stably. |
