description The present invention relates to a battery cell including an electrolyte ion concentration measurement unit and a method for measuring an electrolyte concentration using same. The battery cell according to the present invention comprises a measurement unit in which a first electrode plate, an insulation film, and a second electrode plate are sequentially stacked on one another, wherein the measurement unit is inserted between a separator of the battery cell and an electrode thereof, and thus can directly measure an electrolyte concentration between the separator and the electrode. Therefore, the battery cell can be simply manufactured and has excellent stability. In addition, according to the present invention, the method for measuring an electrolyte concentration of a secondary battery using the battery cell enables measurement of electrolyte concentration in real time even during the use of the battery and can measure an electrolyte concentration of the separator more accurately and quickly than a conventional technology.
