Abstract
A cathode absorption type rectangular tube valve-controlled lead-acid battery is composed of pasted negative electrode, superfine glass fibre diaphragm, rectangular tube positive electrode, casing, safety valve, bus bar, terminals and electrolyte. The rectangular tubular positive electrode is formed by combining rectangular glass fiber braided tubes containing 1-3 conductive lead bars side by side, the surface of the rectangular tubular positive electrode is flat, no tube groove is formed, and an effective oxygen absorption mechanism can be established. The utility model has the advantages of small, light in weight, dark cycle life is long, need not to maintain, can extensively be used for fields such as all kinds of electric motor cars, solar energy and wind energy power station, electric power fork truck, post and telecommunications communication.
Description
The utility model relates to a kind of cathode absorption type tube valve control storage battery, and particularly box-section tubular valve-control storage battery belongs to the sealed lead acid battery field.
Negative electrode in the past absorbs analysing valve control type lead-acid accumulator battery, is all to adopt the plate cream electrode that is coated with to add ultra-fine fibre glass barrier film composition.This is because electrode surface can closely contact with barrier film, can successfully the sulfuric acid of storing in the barrier film be flowed to electrode so that electrochemical reaction and output current to take place, the oxygen that the assurance anode produces in charging process can be transported to cathode surface incessantly and is reduced to water again by plumbous absorption of biscuit through film simultaneously, make battery avoid charging dehydration and the effusion of acid mist outside battery, and cause pollution environment for use.Yet, the plate shortcoming that is coated with the cream positive pole is: in charge and discharge cycles because the variation repeatedly of chemical state (brown lead oxide lead sulfate), be accompanied by expanding and contracting of volume, cause the titanium dioxide lead powder that conducts electricity to come off and cause the decay of battery capacity from electrode body, even internal short-circuit, thereby shortened useful life of battery.In order to address this problem, existing technology is to adopt the tubular type positive plate to be solved: a row cross section is circular glass fiber tube, or a same cross section is enclosed within on the lead for retractable pencil of the positive grid of pectination for circular terylene comb, in pipe, fill lead powder, shut with the dead or direct injection moulding of working of plastics button the bottom then, lead powder can't be come off, thereby constitute the positive pole of tubular type lead-acid battery.The useful life of tubular pole is than much longer times of paste spread type electrode, yet because the positive plate of the tubular type battery of prior art surface pipe trench is very dark, can't be adjacent to the cotton barrier film of ultra-fine fibre glass, the oxygen that anodal surface is produced is easy to directly rise up into along pipe trench the air chamber of battery, the plate negative pole that can't pass barrier film and be resisted absorbs, therefore, can't make the cathode absorption type VRLA battery.Someone adopts gel electrolyte to pour in the pipe trench of this class battery, thereby make tube valve control battery (seeing German sunlight company's product description or Chinese patent XL94229660.5), but the internal resistance of colloid is big, the capacity of battery and heavy-current discharge performance thereof can descend, practical scope is restricted, and the silica gel instability, easily be decomposed into silicon dioxide and water, influence useful life.
The purpose of this utility model provides a kind of good electric property, the cathode absorption type Box-section tubular Valve controlled lead-acid battery of long service life.
The technical solution of the utility model is: Box-section tubular Valve controlled lead-acid battery is made up of positive and negative pole plate, superfine glass fibre partition board, shell and electrolyte, and described positive plate is combined side by side by the rectangular tube that includes the electrically conductive lead muscle.
Electrically conductive lead muscle in the above-mentioned rectangular tube is the 1-3 root, and rectangular tube is the glass wool braided tube that cross section is rectangle, and also can adopt other material to make.
In the above technical scheme, positive plate is combined side by side by rectangular tube, and its surfacing does not have pipe trench substantially, even if consider four jiaos in rectangle because of arts demand is circular-arc, the ditch of Xing Chenging is also very shallow thus, does not influence the applying of ultra-fine fibre glass film to it.After oxygen was separated out from the rectangular tube surface like this, it was very big upwards to rise up into the resistance of air chamber along the surface, and it is very little to penetrate behind the ultra-fine glass film resistance for the negative electrode absorption along surface normal, thereby had set up effective oxygen absorption mechanism.So just improved the electric property of sealed cell, prolonged its useful life.
Below in conjunction with accompanying drawing, further specify embodiment of the present utility model.
Fig. 1 is a positive plate schematic diagram in the utility model;
Fig. 2 is a rectangular tube arrangement profile among Fig. 1;
Fig. 3 is for containing the positive plate schematic diagram of many plumbous muscle in the rectangular tube;
Fig. 4 is a negative plate schematic diagram in the utility model;
Fig. 5 assembles schematic diagram for utmost point group in the utility model;
Fig. 6 is the utility model overall schematic.
As figure, the plumbous matter comb that has comb handle 1 is connected in parallel the 7 plumbous muscle 3 that will be sleeved in the rectangular tube 2, and the cross section of rectangular tube is a rectangle, is become by glass braid, combs last plumbous matter casing seat 6 close-fittings with being located in.Plastics back cover 4 makes lead oxide powder 5 unlikely the coming off that are filled in the rectangular tube.Negative electrode lug 8 links to each other with checker grid 9, and electrically conductive lead muscle 11 is grid-like, and there is biscuit lead 10 side.In utmost point group assembling, be provided with ultra-fine fibre glass barrier film 12 between the positive and negative pole plate, negative terminal 13 links to each other with negative bus-bar 14.Utmost point group is packed in the battery case 17, seal up the battery cover 19 that safety valve 20 is housed, and draw the terminal 18 of battery by dress, pour into dilute sulfuric acid then, charging and changing into gets final product.The utility model also can adopt the electrode 15 and 16 after changing into to form utmost point group, reinstalls in the battery case 17 to form, and this moment, battery generally needed initial charge just can use.
