The invention relates to a battery device and a packaging, dismounting and recovering method of same. The method comprises the following steps of: firstly, arranging an anode conducting assembly in a reaction tank frame, and protruding an anode conducting bump out of the reaction tank frame; subsequently, respectively covering a first opening and a second opening of the reaction tank frame by using two groups of cathode conducting assemblies to form a reaction area capable of accommodating electrolyte; subsequently, laying a metal fixing part on the surfaces of the cathode conducting assemblies and the reaction tank frame; and finally, fastening the metal fixing part by using a fastener. Thus, the battery device provided by the invention for a user has the characteristics of simple structure, rapid packaging, dismountability and recyclability through special structural design, and thus, the problems of difficult packaging and dismounting, difficult recovering and the like caused by complex structure of the traditional battery device are solved.
