摘要： The present invention relates to a stand-alone buoy with a seawater battery, which includes a main body formed to have a predetermined buoyancy so as to float on seawater and provided with a seawater space therein and an inlet formed to introduce the seawater into the seawater space, a position notification part installed on the main body and configured to notify a user of a position of the main body, a solar cell part installed on the main body and configured to generate electricity using sunlight, and a seawater battery unit installed in the seawater space to be submerged in the seawater introduced into the seawater space and configured to react with the seawater to store the electricity provided from the solar cell part and to provide the stored electricity to the position notification part so as to operate the position notification part. The stand-alone buoy with a seawater battery according to the present invention stores the electricity generated by the solar cell part in the seawater battery unit reacting with the seawater, the stored electricity is supplied to an electronic device such as an indicator lamp, and thus there is an advantage in that the stand-alone buoy may be used for a long time without replacing the battery.
