Description
Technical field
The present invention relates to a kind of nickel zinc cell.
Background technology
Due to features such as zinc-nickel cell have height ratio capacity, high-specific-power, high open circuit voltage, cryogenic property is good and cost is low, pollution-free, it be considered to a kind of can be for the new generation of green energy of power vehicle and hybrid vehicle.But the business of zinc-nickel cell utilization is not at present but very extensive, this is mainly because its cycle performance deficiency.The deficiency of zinc-nickel cell cycle performance is mainly that zinc negative pole is unstable, easily produces deformation, zinc dendrite, surface passivation and corrosion and self discharge etc. certainly.So the key of zinc-nickel cell is just to improve the cycle life of zinc negative pole at present.The zinc negative pole of existing nickel zinc cell is all plate type electrode conventionally, this pole plate in manufacturing process in pole plate the quality of active material conventionally inhomogeneous, larger on the consistency impact of accumulator property, be unfavorable for that the series connection of many batteries is used; This plate type electrode is in the process using simultaneously, and active material easily comes off from pole plate, and the life-span to battery and capacity impact are very large.
Summary of the invention
The object of this invention is to provide a kind of tubular type nickel zinc cell.
Technical scheme of the present invention is, a kind of tubular type nickel zinc cell, and by negative pole tube sheet, positive plate is accommodated in plastic casing at negative pole tube sheet, is provided with barrier film between positive plate, adds electrolyte, and opening part is sealed by combination cover cap, and described positive plate is two-sided nickel positive pole; Described negative pole tube sheet is tubular type zinc negative pole, and described tubular type zinc negative pole comprises collector, and on the current-collecting pole of collector, cover has cathode tube, and paste has been clamp-oned in lower end plastic bottom board shutoff for cathode tube in cathode tube.
Described creme is that 100 parts of active materials and 30-50 part concentration are the mixture of the 1.5% HPMC aqueous solution.
The percentage by weight of the described each composition of active material is: zinc oxide: 88.9%-97.6%, zinc powder: 0.6-1.6%, binding agent: 1%-4%, electrically conductive graphite: 0.7-5%, organic inhibition additive: 0.1%-0.5%.
What cathode tube adopted is PP pipe.
What barrier film adopted is pp class barrier film.
Electrolyte is the KOH solution of 6mol/L.
Collector is copper product.
The present invention has following technique effect, first, can guarantee the quality homogeneity of each tubular type zinc negative pole, thereby reach the consistency of accumulator property, secondly the paste of active material and HPMC aqueous solution composition squeezes and in cathode tube, can avoid active material to come off, and improves its life-span.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of tubular type nickel zinc cell, by negative pole tube sheet 2, positive plate 3 is accommodated in plastic casing 1 at negative pole tube sheet 2, is provided with barrier film 4 between positive plate 3, adds electrolyte, opening part is sealed by combination cover cap 5, and described positive plate 3 is two-sided nickel positive pole; Described negative pole tube sheet 2 is tubular type zinc negative pole, and described tubular type zinc negative pole comprises collector 10, and on the current-collecting pole 8 of collector 10, cover has cathode tube 6, and creme 9 has been clamp-oned in cathode tube plastic bottom board 7 shutoff for 6 use lower ends in cathode tube 6; What cathode tube 6 adopted is PP pipe; What barrier film 4 adopted is pp class barrier film; Electrolyte is the KOH solution of 6mol/L; Collector 10 is copper products.
Concrete operations mode
By the zinc oxide of 89 weight portions, the zinc powder of 1.5 weight portions, the acetylene black of 5 weight portions is mixed, adding concentration is 45 parts of the aqueous solution of 1.5% hydroxypropyl methylcellulose, stirring obtains homogeneous creme, then add the concentration that accounts for dry powder weight 3% be 5%PTFE emulsion as binding agent, fully stir, form creme.The creme stirring is clamp-oned in cathode tube 6 by squeezing cream machine, in each cathode tube 6, the gross mass of creme 9 is 50g, then use the other end of plastic bottom board 7 shutoff cathode tubes 6 by bottoming machine, then water washes away the paste outside pipe, then in 70 degrees Celsius dry, obtain tubular type zinc negative pole.
By the welding of copper tubule and 6 tubular type zinc negative poles, make tubular type zinc negative pole be connected in series together (different purposes series connection numbers can change), then (number of variations with tubular type zinc negative pole changes with the two-sided nickel positive pole that is connected in series to, always than the few a slice of zinc negative pole) be staggeredly placed, finally barrier film is inserted into successively between tubular type zinc negative pole and two-sided nickel positive pole.
Then the both positive and negative polarity inner core assembling is accommodated in plastic casing 1, injects electrolyte (KOH of 6mol/L), then seal with combination cover cap 5, make tubular type zinc-nickel cell.
Zinc-nickel cell carries out cycle life test after changing into: tubular type zinc-nickel cell, with 0.2C charging 5.5 hours, then discharges with 5C, and the final voltage of electric discharge is 7.2V, record discharge capacity, shelve 10min, then discharge and recharge continuously by said procedure, until discharge capacity is less than 6Ah.Test result shows, tubular type zinc-nickel cell and common zinc-nickel cell comparison, and cycle life exceedes 500 times, cycle life good (as shown in Figure 4).
