One method currently commonly employed in the industry to detect battery sealability is: firstly, immersing a battery to be tested in a detection liquid, then injecting high-pressure gas into the battery, and observing whether bubbles are generated, if so, the sealing performance is poor, otherwise, the sealing performance is good. Another common method is: firstly, compressed air with certain pressure is filled into the battery, after the air is filled and balanced, an air source is cut off, and then the pressure drop in the battery in unit time is measured through a pressure measuring device, an instrument and a meter. The method is low in efficiency, on-line automatic detection cannot be realized, and therefore the potential leaked battery is transferred to the next working procedure or the risk in the using process, and great potential safety hazards are caused.
