Abstract
The utility model discloses a flat-plate integrated pipe maintenance-free electromobile polar plate, and relates to the technical field of storage batteries. The flat-plate integrated pipe maintenance-free electromobile polar plate comprises a positive electrode or negative electrode slab lattice, wherein ribs are arranged on the slab lattice; and a polar tab is arranged on the upper part of the slab lattice. The flat-plate integrated pipe maintenance-free electromobile polar plate is characterized in that lead paste is coated on the ribs; and a protection layer is sleeved outside the slab lattice and can wrap the slab lattice and the ribs. By adopting the flat-plate integrated pipe maintenance-free electromobile polar plate, the problems that the conventional powder filling technical pipe type polar plate is large in size and low in active substance utilization rate, is complicated in manufacturing and is not environment-friendly in powder filling and grinding, and the common pipe type polar plate cannot be made to be a maintenance-free battery are solved; the service life of the flat-plate integrated pipe maintenance-free electromobile polar plate is twice or three times of that of the common same polar plate; and the active substance utilization rate is improved by over 25 percent when being compared with the active substance utilization rate of the common pipe type polar plate.
Description
Technical field
The utility model relates to the battery technology field, is specifically related to a kind of dull and stereotyped integral tube, non-maintaining electric motor car pole plate.
Background technology
Storage battery is a kind of in the battery, and its effect is limited power storage, uses in suitable place.Its operation principle is converted into electric energy to chemical energy exactly.Along with the development of modern industry, need to use the product of storage battery more and more, so that market is also increasing to the demand of storage battery, the output of storage battery also increases day by day.
Along with the progressively understanding of the excellent properties of people to the tubular type battery, particularly long-life performance, the production scale of domestic tubular type battery heats up gradually.One of key factor that affects the tubular type battery life is to handle the elongation problem of pole plate well, because the elongation of battery operated middle pole plate is that inevitably especially along with the increase of cycle period, the elongation problem shows more obviously.The basic structure of tubular plate is cylindric lead for retractable pencil in the middle of being in the tubular type battery, and peripheral matcoveredn is filled active material between the two.Pole plate when assembling, lead for retractable pencil to be packed in the endoporus of fixture, protective layer plays position-limiting action.
Tubular plate active material injection mode is common for squeezing cream \ pier powder dual mode, be about to lead plaster or lead powder by establishing special equipment and clamp-on or injecting in the comb, the homogeneity of active matter quality is difficult to control, between the active material and between active material and the lead for retractable pencil in conjunction with tightness degree can not show a candle to grid type plate evenly, consistent, the otherness of this combination degree obviously affects giving full play to of pole plate excellent properties.As described in Figure 3, traditional tubular plate mainly by entablature 20, sill 21 and be connected to entablature 20 and sill 21 between lead pipe 22 form, enter lead powder at lead pipe 22 interior piers.The pole plate production efficiency of this structure is very low, and lead powder easily corrodes lead pipe and leaks, and pollute, and useful life is shorter.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of long service life, the dull and stereotyped integral tube that active material utilization is high, non-maintaining electric motor car pole plate.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of dull and stereotyped integral tube, non-maintaining electric motor car pole plate; comprise a negative or positive electrode grid; be provided with rib at grid; be provided with lug on grid top; it is characterized in that: be coated with lead plaster at described rib; be provided with protective layer in the grid outer cover, protective layer can wrap up grid and rib.
Wherein lead plaster is coated on rib and the grid uniformly.
Described protective layer is made on grid by the method for making, and every rib can be wrapped up separately, can prevent that lead plaster from leaking or come off.
Described protective layer is made by the acid resistance material, strengthens the useful life of protective layer.
Preferred acid resistance material is the dry goods material.
Preferred dry goods material is the cloth with permeability.
The beneficial effects of the utility model are:
1. be more than two to three times of common similar pole plate useful life of the present utility model, and active material utilization improves more than 25% than common tubular plate;
Customer service former powder filling technique tubular plate volume large, active material utilization is low, do manual work complicated, powder filling, the not environmental protection of pier powder, common tubular plate is bad makes the difficult point such as maintenance-free battery;
Customer service current trend technique squeeze the cream method and can not be difficult to the consistent difficult problem of assurance by large-scale and elongated pole plate and active material weight;
4. provide reliable guarantee for Large Electric tractor electric automobile uses lead acid accumulator, made the battery of electric vehicle performance that tremendous development arranged;
5. can make non-maintaining type, avoid acid mist and leaking of acid solution and cause environmental pollution and etching apparatus to cause personal injury, can avoid hydrogen to efflux causing blast and the device damage and the personal injury that occur;
6. the volume of battery be can dwindle and volume ratio ability and the gravimetric specific energy of battery improved.
