Electrolyte Detection Device and Secondary Battery Transfer Facility Comprising the Same

The present invention relates to an electrolyte detection device. The electrolyte detection device comprises: a contamination detection plate configured to contact any one surface of a secondary battery, in which an opening is provided; first and second conductors provided to be spaced apart from each other so that current does not flow on a surface of the contamination detection plate, the first and second conductors being electrically connected to each other by an electrolyte leaking from the opening of the secondary battery; a power member comprising a positive electrode connected to the first conductor and a negative electrode connected to the second conductor; and a contamination detection member configured to detect whether the electrolyte leaks through the current generated when the first conductor and the second conductor are electrically connected to each other.
