  "textContent": "A rechargeable battery state determination method determines whether a rechargeable battery is in a micro-short-circuit-prone state, which is a state that is highly likely to form a micro-short circuit. The rechargeable battery state determination method includes measuring an electron transfer resistance of the rechargeable battery by applying a voltage or current having a predetermined or higher frequency to an electrode system of the rechargeable battery, determining whether an inter-electrode distance is satisfactory based on a comparison of the measured electron transfer resistance of the rechargeable battery with a predetermined lower limit threshold value, in which the determining whether an inter-electrode distance is satisfactory including determining that the inter-electrode distance is satisfactory when the measured electron transfer resistance of the rechargeable battery is greater than or equal to the lower limit threshold value, and determining that the rechargeable battery is a conforming piece when the inter-electrode distance is satisfactory.",
