Secondary battery comprising tanks made from printed circuit board material

The present invention is a secondary battery, comprising an upper housing (101), an upper accommodated tank (105), a main component of battery (109), a lower accommodated tank (107), a lower housing (103) each is laminated orderly by layers to form a sealed structure of the secondary battery. The upper accommodated tank is made of a printed circuit board (PCB) material and is used to accommodate electrolyzed material. The lower accommodated tank is made of printed circuit board material and used to accommodate the electrolyzed material. The main component of the secondary battery is inserted between the upper accommodated tank and the lower accommodated tank.
