Chinese patent 200620069267.7 discloses a kind of high-capacity nickel-hydrogen battery, comprises positive plate, negative plate, barrier film and battery case; Rolled alloy powder on the negative plate, and formed a white edge that does not contain alloyed powder in the negative plate lower edge, the white edge lower surface is welded with the afflux dish, and negative plate is reeled by the low resistance copper mesh and formed, and afflux is made an inventory and is welded in the battery case inner bottom part.This patent disclosure should be the circle battery combination; Big electric current bottleneck effect is serious, battery self temperature rise, poor stability, after-sales service difficulty.
Summary of the invention
The invention provides that a kind of volume is little, internal resistance is little, the power type square body nickel-hydrogen battery group of the module electric core that electric current is big.
A kind of power type square body nickel-hydrogen battery group of module electric core, comprise shell, shell inner cavity is divided into several cells by dividing plate, be provided with the unit electricity core of forming by positive plate, negative plate and barrier film in each cell, all unit electricity cores discharge side by side, adjacent in twos unit electricity core output polarity is opposite, and with the brace formation module electric core that is together in series; Positive plate, the end edge that the negative plate direction is opposite leave white edge, and white edge welds mutually with brace; The positive electricity end or the extreme brace prolongation of negative electricity that are positioned at outermost Unit two electricity core are welded with the same polarity electrode column that passes shell.
The outer wall of shell is provided with crisscross guiding gutter, and guiding gutter is an arc watt shape, and inwall is provided with recessed threaded line.Help circulation of air and heat distributes, and be convenient to tie up.
Be with sealing ring and sealing gasket on the positive and negative electrode post between shell and brace, the end that the positive and negative electrode post passes shell is with packing ring and back tightening nut.
Shell is provided with the special-shaped safety exhaust that can repeat fluid injection.It is not maintainable to change sealed cell.
Also be coated with heat sink material on the outer shell outer wall.
The novel power type square body nickel-hydrogen battery group of module electric core provided by the invention, its unit electricity in-core battery lead plate is provided with white edge, the space that can weld the large tracts of land brace is provided, reduced the dynamic internal resistance of battery, power consumption and battery temperature rise when reducing the big electric current of transmission, reduction power delivery bottleneck has improved the overall power of battery, guarantees that battery is stable, work safety.
