(1) the cylindrical cell electrode pad set is fashionable is takeup type, and electrode slice is subject to the physical property injury, is easy to generate unsafe factor.
(2) cylindrical cell electricity core self-heating amount is higher near the center, and surface area is little, is unfavorable for heat radiation, the battery performance instability.
(3) traditional cylindrical cell single electrode block place syndeton limitation is the bottleneck of big current delivery.
Present domestic side body outer battery product double electric pole columns seat is the same side end face of battery, and promptly the positive and negative electrode position is at the same end face of battery, and the transmission channel of this structure is narrow, the blocking current passage.
Chinese patent 200620069267.7 discloses a kind of high-capacity nickel-hydrogen battery, comprise positive plate, negative plate, barrier film and battery case, rolling on the negative plate have an alloy powder, and at white edge that does not contain alloyed powder of negative plate lower edge formation, the white edge lower surface is welded with the afflux dish, negative plate is reeled by the low resistance copper mesh and is formed, and afflux is made an inventory and is welded in the battery case inner bottom part.The Ni-MH battery of this patent disclosure is a cylinder, can to a certain degree reduce contact resistance, but adopts traditional single-ended block battery structure, and dynamically internal resistance and power consumption are big, and big current transmission characteristic is poor, and temperature rise is fast, and radiating effect is bad; Especially the dynamic heat regenerative in inboard junction of blocking a shot is given electric core, aggravation battery instability.
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 invention provides a kind of double electric pole columns power type square body nickel-hydrogen battery, positive and negative electrode is reasonably designed in the battery both ends of the surface respectively, improve the power delivery ability, reduce 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 electrode column of the same polarity of passing housing the another side of flow collection sheet.
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.
Power type cube double electric pole columns Ni-MH battery provided by the invention, 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.
