The conventional prismatic cell pattern is the single end face bipolar electrode.Its structure is crowded, and the current delivery passage is narrow, and power consumption is big, and the battery temperature rise is obvious, also exists heat regenerative in electric core problem, influence stability, and power characteristic is not played well.
Summary of the invention
The utility model provides a kind of double electric pole columns power type square body nickel-hydrogen battery, and positive and negative electrode is reasonably designed in the battery both ends of the surface respectively, improves the power delivery ability, reduces temperature rise.
A kind of double electric pole columns power type square body nickel-hydrogen battery, comprise housing and be located at the electric core of forming by positive plate, negative plate and barrier film in the housing, described positive plate, the end edge that the negative plate direction is opposite leave white edge, and white edge welds mutually with a side of flow collection sheet; Weld mutually with the positive electricity pole that passes housing the another side of the flow collection sheet that welds mutually with white edge on the positive plate, and weld mutually with the negative electricity pole that passes housing the another side of the flow collection sheet that welds mutually with white edge on the negative plate.
The outer wall of housing is provided with crisscross arc watt shape guiding gutter, and the inwall of guiding gutter is provided with recessed threaded line, is convenient to the heat radiation of battery pack and ties up.
Apply one deck heat sink material on the outer wall of housing, improve the battery radiating rate.
All be with sealing ring and sealing gasket on the positive and negative electrode post between flow collection sheet and the housing.Improve battery hermetization.
The end that the positive and negative electrode post passes housing is with packing ring and back tightening nut.
The housing outer wall is provided with special-shaped safety exhaust, discharges excess air in the battery, improves the security performance of battery, changes the not maintainable design of sealed cell.
The power type cube double electric pole columns Ni-MH battery that the utility model provides, adopt unconventional structure, positive and negative electrode is located at the battery both ends of the surface respectively, strengthened the transmission channel of electric core and foreign current, reduce the dynamic power consumption and the internal resistance of battery, improve big electric current transmission performance, prolongation recycles the life-span.
