The invention provides a battery device and a method for packaging, disassembling, and recycling the battery device, wherein the anode conductive element is disposed in a reaction trough frame with a bump thereof protruding from the frame; two sets of the cathode conductive elements cover on a first opening and a second opening of the reaction trough frame, respectively, so as to form a reaction region for accommodating electrolyte therein; and a metallic fastener is disposed on surfaces of the cathode conductive elements and the reaction trough frame and fastened with a buckling member. The invention provides a simple structure that can be packaged rapidly, disassembled and recycled to thereby overcome the drawbacks of conventional batteries.
