Description

Nickel-hydrogen accumulator

The utility model relates to a kind of battery, especially a kind of nickel-hydrogen accumulator.

In the storage battery of more than 400 specification of nine big classes of China's production at present, comprise that motorcycle battery is lead acid accumulator, its material therefor is plumbous or lead-calcium alloy, manufacture pole plate, with be combined into anode and negative electrode with the acid and alkali-resistance separator material, after injecting electrolyte chemical reaction takes place and produce elementary charge.The battery that needs to inject electrolyte claims wet lotus formula storage battery, must not inject the dry charged battery that is of electrolyte.Up to the present, these two kinds of batteries all are widely used in motor vehicle-mounted starting battery, and other fixed acid proof type lead acid accumulators all are used among defence engineering, the post and telecommunications equipment, and the acid proof type lead acid accumulator adopts the tubular type positive plate, the paste spread type negative plate involves great expense.What of pole plate and dividing plate the charging characteristic of existing motor lead-acid storage battery be according to, determine its rated voltage, on predetermined data, make vary in size, specification that thickness is different, determine its charged capacity, be combined as 1 group as prerequisite and be shaped as a unit like a rectangular box, its every group of rated voltage is 2V, according to this series system connect behind the required utilization voltage of the electrical appliance that draws, be installed in the battery case interior (being shell) that plastics are made, battery case is made product with the viscose glue sealing.

Lead-acid battery has advantage: capacity is big, start in the conservation of power, low temperature environment, why can be used among defence engineering, the post and telecommunications equipment.The shortcoming of lead acid accumulator maximum is that lifetime limitation is short, no matter it is charged on Plante-type plate and dividing plate that lead acid accumulator dry type, wet type after chemical reaction produce negative ions, thereby make the pole plate dividing plate produce oxide layer, because electrolyte (dilute sulfuric acid) has certain corrosivity, thereby make the electrode surface oxidation, electrode top layer current collection lotus is reduced, hinder its conductive capability, cause the charged ability of relative minimizing to cause capacity to reduce.Simultaneously, oxide layer is through shaking, coming off, reoxidize, come off, make battery lead plate shortening in useful life, its common life-span can normally be used at the various electrical appliances of maintenance and is prerequisite, life-span is about 2 years, and why this point occurs the maintenance battery industry everywhere according to using the user of lead-acid battery to confirm, change pole plate, dividing plate, charge, add electrolyte etc. for lead-acid battery, cause wasting great amount of manpower and material resources, financial resources.Also there is a latent defect in lead-acid battery, just be to use storage problem in the way: many people think, deposit and do not use storage battery, just there is not loss, can not influence its life-span, it is opposite in fact being in harmony, and does not use even deposit, the chemical reaction of original charge generation corrodes pole plate, dividing plate, minimizing life time equally.

The purpose of this utility model provides that a kind of cycle charge discharge ability is strong, the long-life, make in the purposes resting period long, does not have and corrodes non-maintaining nickel-hydrogen accumulator.

The utility model is to adopt a plurality of Ni-MH battery monomers, combines through series connection and parallel circuits.Through series connection and combination in any in parallel, the rated voltage series circuit of the synthetic approved product regulation of Ni-MH battery set of monomers, according to Ni-MH battery monomer different size, different nominal capacity, combination in any reaches the parallel circuits of the nominal capacity of approved product regulation, is assembled into approved product and uses for different electrical equipment.

This battery also has three big advantages except that having the total advantage of lead-acid battery: the cycle charge discharge ability by force, extra long life, make in the purposes resting period long, non-maintaining entirely, easy to use, advantage such as starting performance is good.

Elaborate below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model line map.

Among the figure, Expression monomer ni-mh, battery 1,

The expression connecting portion.

The utility model adopts a plurality of Ni-MH battery monomers (1) to combine, its each monomer rated voltage is that 1.2V, each monomer capacity are that 1An, 1.6An, 1.8An, 2An, 2.4An, 2.8An, eight kinds of specifications of 3.5An, 4An are for selecting combination in any arbitrarily.Again according to the required different rated voltage of various electrical appliances, different nominal capacity decisions is through any series circuit, parallel circuits arbitrarily, and be assembled into the fixed product of the nominal capacity of the rated voltage of regulation and regulation, use for various dispar electrical appliances.

Raw material adopt ni-mh cell qualified products, provide by producing man of monomer Battery Plant, equipment welds with the high precision spot welding machine, is content the alloying metal of the zinc-plated amount of 100 grams, thickness is 0.3mm, widely cut off into length for the alloy bar of 1cm, length is on demand finished serial connection, the in parallel combination as connecting sheet metal.

Ni-mh monomer (1) is shaped as the garden cylindricality, and unified diameter is 16.3mm, highly is the following different specification of 65.8mm, promptly the difference according to amount of capacity produces relative scale, capacity is greatly promptly high, capacity is little promptly short, and having several is unified diameter, and the specification of disunity height.

Cell is stood up by vertical, press from the vertical end face of battery: positive pole, negative pole, positive pole, negative pole, positive pole, negative pole are by that analogy, from left to right, connect and be arranged in the assigned voltage that is arbitrarily made with approved product, respectively keep a positive pole, a negative pole end end to end, weld during capacity in parallel for following step.Can require nominal capacity according to the rated voltage that approved product requires, carry out the series, parallel Combination Welding.

For example: it is 12V that approved product requires rated voltage, nominal capacity is 9An, its planform is: selecting cell for use is the specification of 3An, 10 the monomer ni-mh cells of connecting, 10 is one group, connect 3 groups be the positive pole of approved product for three groups in parallel at every group positive terminal again, be the negative pole of approved product for three groups in parallel at every group negative pole end, totally 30 the cells composition rectangular shapes after institute makes up.

This cell voltage is 6V and 12V, and capacity is 4-100A.n.Battery is a dry charged type cycle charge discharge storage battery, and charging back use earlier can be started under-20 ℃ of environment, and starting power is big, and every technical indicator can be up to state standards.This storage battery is applicable to various motorcycles, car, computer, emergency power supply, mine lamp power etc.

Claims

1, a kind of nickel-hydrogen accumulator is made up of battery cell, and base is characterised in that: adopt a plurality of Ni-MH battery monomers (1), combine through series connection and parallel circuits.
