PURPOSE: A battery having a trench structure and a method for fabricating the battery are provided to improve the quality of the battery by adopting a trench structure into the battery. CONSTITUTION: A battery comprises a substrate(10). The first collector(1) is formed on the substrate(10). A cathode(2) is formed on the first collector(1). An electrolyte(3) is formed on the cathode(2). An anode(4) is formed on the electrolyte(3). The second collector(6) makes contact with the anode(4). One of the first collector(1) and the cathode(2) is etched so as to form a plurality of trenches. The remaining thin film elements are sequentially deposited on the trenches so that the amount of the cathode(2) and the effective contact interface between the cathode(2) and the electrolyte(3) are increased.
