Abstract
The invention discloses a single-face-coated storage battery pole plate which comprises a lead-alloy grid, a polytetrafluoroethylene partition and a protecting film. The polytetrafluoroethylene partition is arranged at a position 1/2-2/3 of the thickness of the lead-alloy grid, lead-plaster active ingredients are coated on the front of the lead-alloy grid, and the protecting film is coated on the back of the lead-alloy grid. By the single-face-coated storage battery pole plate, capacity, performance and service life of a battery can be effectively guaranteed, total mass of the battery can be lowered, mass ratio capacity of the battery is improved, and application fields of products can be increased.
Description
Technical field
The invention belongs to the Lead-acid Battery Technology field, relate in particular to the battery pole plates technology.
Background technology
At present, the manufacturer of nearly all lead acid accumulator has all adopted the production technology of dual coating to carry out the production of pole plate, and the quality of analyzing known storage battery 50%-60% in conjunction with the finished product battery in existing technical scheme all concentrates on pole plate.And show according to our analysis and experimental data, it is not participate in electrochemical reaction that the pole plate at battery module two ends adopts dual coating actual, therefore belongs to waste, and the quality of the whole storage battery increased, and has reduced the specific discharge capacity of battery.
Therefore this type of pole plate can adopt the scheme that single face applies.Thereby reduced the quality of whole storage battery, improved the specific discharge capacity of battery.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this invention is to provide a kind of single face and applied accumulator plate, there is higher specific discharge capacity, reduced the use amount of lead plaster, reduced costs.
Technical scheme: for achieving the above object; the present invention is by the following technical solutions: a kind of single face applies accumulator plate; comprise lead alloy grid, polytetrafluoroethylene dividing plate and diaphragm; described polytetrafluoroethylene dividing plate is located at 1/2～2/3 place of lead alloy grid thickness; the front surface coated of lead alloy grid has the lead plaster active component, and its back side is coated with diaphragm.
As preferably, the structure of described lead alloy grid is radial.
As preferably, described diaphragm is PET film or polyvinyl resin film.
Beneficial effect: compared with prior art, the present invention has the following advantages: be at first capacity, the performance and used life that can effectively guarantee battery, reduce the gross mass of battery, improved the specific discharge capacity of battery, can improve the application of product.Take 12V100Ah as example, the mode that adopts single face to apply when the negative plates at two ends, anode plate and middle negative plate all use original scheme, in the situation that do not change remaining any parameter, the quality by the preliminary whole battery of calculating can reduce 1-1.5Kg.Secondly, the technology that the pole plate of part takes single face to apply, the use amount of having saved the raw material lead plasters; The 3rd, apply one deck polymeric membrane or new technology that the print method of directly taking pictures is pressed onto PET rete and 5um polythylene resin binding agent on grid can effectively be alleviated the corrosion of grid in acid solution on the non-coated side of negative pole.The 4th, the pole plate production of novel improved is less demanding to production line and relevant device thereof, and a lot of flow processs can complete on original equipment.。
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, lead alloy grid 1, polytetrafluoroethylene dividing plate 2, diaphragm 3
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As Fig. 1 shows; a kind of single face applies accumulator plate; comprise lead alloy grid 1, polytetrafluoroethylene dividing plate 2 and diaphragm 3; described polytetrafluoroethylene dividing plate 2 is located at 1/2～2/3 place of lead alloy grid 1 thickness; the front surface coated of lead alloy grid 1 has the lead plaster active component, then by photograph print method, PET film or polyvinyl resin bonding agent is overwhelmed on the grid back side.
The mould of the grid that current company is produced carries out modification a little, the thorax body translation of a side mold present thickness 1/3, remaining lines is consistent.Now carry out adopting the polymer plastic flitch of PTFE to be illustrated after the grid of gravity casting method formation.
The technological process of the tight lining of the process using of PTFE, concrete: surface treatment---------adhesive curing---inspection---finished product is heated in water flowing to be coated with glue caking agent in welding.Although the method technological process is more, process simple.The advantage had is that compactness is good, is difficult for be full of cracks and comes off, and has good acid corrosion-resistant.If added some specific additive in PTFE, can also greatly improve its mechanical property.
After the production of the conducting polymer plastic plate in the middle of having completed, lead alloy grid 1 can be sent on current coating line and be applied.Apply after end is solidified the print method of directly taking pictures and PET rete and 5um polythylene resin binding agent are pressed onto to the non-coated side (being the back side) of grid.
Not only can effectively reduce the coated weight of lead plaster like this, reduce the pole plate quality of battery, reduce the quality of whole battery, can also effectively guarantee the capacity of battery, improve the useful life of battery, improved the specific discharge capacity of battery, increase the core competitiveness of product.
