Said positive collector electrode device is made up of a plurality of collector electrode intermediate plates, and an end of said positive electrode lug is arranged between two adjacent said collector electrode intermediate plates.
Said collector electrode intermediate plate be shaped as circle.
Said negative electrode lug and said positive electrode lug are distributed in the two ends of said electric core.
Surface at said cap is provided with liquid injection hole, and said liquid injection hole is arranged between said positive electrode and the said negative electrode.
Inside at said housing is filled with electrolyte.
Compared with prior art, the utlity model has following advantage:
The novel cylindrical cell that the utility model provides; Comprise housing, cap, electric core, negative electrode and positive electrode; Negative electrode and positive electrode are installed in the surface of cap, and the negative electricity extremely interior electrode of lower end is connected, and electric core is arranged on the inside of housing; Top and bottom at electric core is respectively equipped with negative collector electrode device and positive collector electrode device; The negative collector electrode device is connected with electric core through the negative electrode lug, and the positive collector electrode device is connected with electric core through the positive electrode lug, and negative plate collector electrode device is connected with interior electrode through conductor.The utility model is rational in infrastructure; The internal short-circuit that can effectively prevent the battery that the inefficacy owing to the insulating barrier on the lug causes causes the blast generation of combustion phenomena of battery; Through adopting the collector electrode device lug at electric core two ends is collected; Avoided any type of contact of positive and negative lug, made collector electrode device separately, can well carry out welding operation owing to adopt with interior electrode that need be connected separately and housing identical materials.
