PURPOSE: A lithium air battery device is provided to vibrate materials composing a positive electrode, and lithium peroxide precipitated in the positive electrode, thereby improving performance by detaching or crushing lithium peroxide, which blocks pores for air-inflowing, from pores. CONSTITUTION: A lithium air battery device comprises a positive electrode in which oxygen is reduced, electrolyte in which lithium ion is able to move, a negative electrode in which lithium is oxidized, and a separator separating the positive electrode and the negative electrode by being arranged in the electrolyte. The positive electrode consists of carbon and a catalyst. The negative electrode consists of lithium metal. The battery device additionally comprises an ultrasonic generator vibrating lithium peroxide precipitate by generating ultrasonic wave. |
