Wherein, be provided with interval in described battery compartment to be stacked and the N block positive plate be connected in parallel and N+ block negative plate.
Wherein, the skin of described negative plate is enclosed with alkaline-resisting cotton paper and polymer micro graft copolymer membrane respectively.
Wherein, two panels negative plate is wrapped in same polymer micro graft copolymer membrane after the alkaline-resisting cotton paper of parcel, and doubling afterwards also inserts positive plate between two panels negative plate.
Wherein, described lower house is cuboid, and is provided with and flushes with cavities open, for splitting the interlayer of battery compartment.
Wherein, the positive pole of high order end battery compartment, the negative pole of low order end battery compartment connect positive terminal and negative terminal respectively.
Wherein, also comprise the upper shell as lower house top cover, described upper shell is provided with the reserved opening of positive terminal, negative terminal.
Wherein, the upper shell as lower house top cover is also provided with the liquid injection hole for injection electrolyte corresponding respectively with described cavity.
Wherein, the upper end of liquid injection hole is provided with seal cover board.
Wherein, the seal groove be also provided with for sealing with lower house of upper shell, is marked with epoxy sealing glue in described seal groove.
Compared to the prior art the present invention, adopts the battery design of square disjunctor, alleviates battery container weight, reduce battery volume, thus reaches raising zinc-nickel cell energy density.Such design saves the shell of each battery unit, thus makes integral battery door compacter, alleviates the weight of integral battery door, reduces battery cost, and improves the energy density of battery, strengthens zinc-nickel cell in the market competitiveness.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
See accompanying drawing, 1 is lower house, and 2 is nickel electrode, and 3 is zinc load, and 4 is positive terminal, and 5 is negative terminal,
6 is upper shell, and 7 is liquid injection hole, and 8 is seal cover board.
Embodiment
Now by reference to the accompanying drawings the present invention is further described.
What show see Fig. 1, Fig. 1 is one embodiment of the present of invention, and comprise lower house 1, lower house 1 is in cuboid, and lower house 1 is provided with six cavitys that there is opening upper end, and is provided with and flushes with cavities open, for splitting the interlayer of battery compartment.Also comprise six battery compartment, connected by the mode of series connection successively between battery compartment, and be placed in respectively in corresponding cavity.Be provided with interval in battery compartment to be stacked and be connected in parallel 11 pieces of positive plates and 12 pieces of negative plates.
Positive plate is take nickel foam as currect collecting net, through slurry coating active material, then passes through the process of oven dry, cut-parts, welding electrode ear, for subsequent use after cover diaphragm bag.
Negative plate cut with tin-coated copper draw in the net, zinc-plated steel band, tin-coated copper mesh grid be collector, through slurry coating active material, then drying, roll-in, cut-parts, welding electrode ear process, carry out coating subsequently.
Coating is as preferably, and the skin of negative plate is enclosed with alkaline-resisting cotton paper and polymer micro graft copolymer membrane respectively.Two panels negative plate is wrapped in same polymer micro graft copolymer membrane after the alkaline-resisting cotton paper of parcel, and doubling afterwards also inserts positive plate between two panels negative plate.
Subsequently, the positive pole (i.e. nickel electrode 2) of the positive and negative plate stacked and negative pole (i.e. zinc load 3) are welded together respectively, then insert in each cavity (being the space of the band opening of formed unit trellis); All insert after positive and negative lug battery pole piece welded together respectively until six cavitys, first the nickel electrode 2 between adjacent cavity and zinc load 3 are welded together, form being connected in series of each battery compartment.The nickel electrode 2 of high order end battery compartment and positive terminal 4 are welded together afterwards, zinc load 3 and the negative terminal 5 of low order end battery compartment weld together, and complete the welding of the positive terminal 4 of battery cell, negative terminal 5 extraction.
Also comprise the upper shell 6 as lower house 1 top cover, upper shell 6 is provided with the reserved opening of positive terminal 4, negative terminal 5.The seal groove be also provided with for sealing with lower house 1 of upper shell 6.After having welded, pour into epoxy resin sealant in the position of the extraction opening of the seal groove of upper shell 6 and positive terminal 4, negative terminal 5, complete the sealing of cell housing.
Upper shell 6 as lower house 1 top cover is also provided with the liquid injection hole 7 for injection electrolyte corresponding respectively with cavity, adds in each battery compartment, then cover a certain amount of electrolyte seal cover board 8 and sealed by liquid injection hole by liquid injection hole 7.Finally by charging/discharging apparatus to the present embodiment according to certain fertilizer alleviant, repeatedly discharge and recharge is carried out to battery, completes the activation of active material in battery, and make the using state that battery reaches best.
