Abstract: The disclosure relates to a tobacco material including a flavor material and a method of preparing the tobacco material. The tobacco material may have a core-shell structure in which a core includes a first tobacco mixture and a flavor material and is surrounded by a shell including a second tobacco mixture, such that the aerosol generating article including the tobacco material generates a characteristic flavor.

Abstract: A water electrolysis device includes an electrolyte correction unit having a diaphragm, the device having an electrolyte correction unit, including a diaphragm, for removing a concentration difference inside an electrolyte, so as to prevent a gas composition in a gas phase area of the water electrolysis device from reaching an explosion limit and, simultaneously, prevent the occurrence of a difference in a liquid level due to a difference in the concentration of the electrolyte even if the electrolyte discharged from an anode chamber and the electrolyte discharged from a cathode chamber are each circulated independently, and thus does not require an additional device for solving same, and can resolve the problem of a reduction in processability according to electrolyte re-injection and operation stabilization.

Abstract: An embodiment of the present disclosure discloses tobacco material including: a center portion including a flavor material; and an outer portion including a tobacco mixture, wherein the outer portion surrounds the center portion.

Abstract: The present disclosure relates to a water electrolysis apparatus including a diaphragm for removing a dissolved gas from an electrolyte. By separating a dissolved gas present in an electrolyte through a diaphragm provided in a gas-liquid separator or an electrolyte circulation line, the water electrolysis apparatus can increase the efficiency of production of the dissolved gas in the electrolyte while preventing a gas composition from reaching an explosive limit in a gas phase region of the water electrolysis apparatus.

Abstract: Provided is an auxiliary battery system of a vehicle, the auxiliary battery system comprising an auxiliary battery of the vehicle, which comprises a plurality of cells, and a battery controller configured to perform balancing between voltages between the plurality of cells of the auxiliary battery, the battery controller comprising a cell balancing control unit configured to perform balancing based on voltages of the plurality of cells when ignition of the vehicle is ON, and perform balancing based on a voltage deviation between the plurality of cells when the ignition of the vehicle is OFF.
