Abstract
The utility model relates to a kind of battery, in particular to a dynamic cathode absorption valve controled seal lead battery. The utility model comprises a box, a fluid filling mouth and a pressure relief valve. The inside of the fluid filling mouth is provided with microporous ptfe filter washers with an opening provided thereon and palladium beads. The utility model has concise structure and good hydrogen and oxygen composite effect and is an ideal battery.
Description
One, technical field
The utility model relates to a kind of storage battery, relates in particular to the valve-control sealed lead accumulator of a kind of cathode absorption type.
Two, background technology
At present, the hydrogen that the valve-control sealed lead accumulator of the cathode absorption type on the market produces in charging process is combined to the water by oxygen cycle except that inside again, and unnecessary gas is all discharged by pressure relief valve.The disadvantage of this structure is that storage battery oxyhydrogen absorptivity can not 100%, and charging for a long time or the long-time back of using unavoidably want dehydration dry, influences energy content of battery storage, in the time of seriously thermal runaway can take place, and are out of shape, and cause battery not use.
Three, summary of the invention
The purpose of this utility model is to provide a kind of unnecessary aerification synthetic water that produces can be with charging time the, the storage battery that refluxes and use.
The utility model is a kind of storage battery, comprises casing, filling opening, and pressure relief valve is equipped with expanded microporous polytetra fluoroethylene-EPTEE filter and palladium pearl in the filling opening, have gap on the expanded microporous polytetra fluoroethylene-EPTEE filter, and the quantity of palladium pearl is the 1-50 grain.
After the utility model adopts said structure, its advantage is: the expanded microporous polytetra fluoroethylene-EPTEE filter can fall the acid liquor filtering of carrying secretly in the gas that produces in the charging process, the palladium pearl then regroups the gas that produces in the charging process as catalyst and is to be back to water in the battery by the gap on the expanded microporous polytetra fluoroethylene-EPTEE filter.Meet the naked light accident of easily blasting thereby avoided storage battery itself because hydrogen, carrier of oxygen are overflowed, the water that gas generated simultaneously returns in the storage battery, has slowed down the storage battery dehydration greatly, the dry time, has prolonged useful life of storage battery.
The utility model said structure can be widely used in electric vehicle, rise employ, energy storage is with in the valve-control sealed lead accumulator of cathode absorption type.
Four, description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Five, embodiment
A kind of storage battery comprises casing 1, filling opening 2, and pressure relief valve 3 is equipped with expanded microporous polytetra fluoroethylene-EPTEE filter 4 and palladium pearl 5 in the filling opening 2, have downward-sloping gap 6 on the expanded microporous polytetra fluoroethylene-EPTEE filter 4, and the quantity of palladium pearl 5 is the 1-50 grain.
Of the present utility modelly be: open the pressure relief valve 3 on the storage battery casing 1, put into expanded microporous polytetra fluoroethylene-EPTEE filter 4 in the filling opening 2 earlier, put into the palladium pearl 5 that quantity does not wait then, cover pressure relief valve 3 again and get final product by process of assembling.
When the utility model uses, expanded microporous polytetra fluoroethylene-EPTEE filter 4 falls the acid liquor filtering of carrying secretly in the gas that produces in the battery charging process earlier, 5 on palladium pearl regroups the gas that produces in the charging process as catalyst again and is to be back to water in the storage battery by the gap on the expanded microporous polytetra fluoroethylene-EPTEE filter 6.
Technical indicator of the present utility model is: the hydrogen efficiency 95% that disappears, backflow efficient 85% is analysed acid number 0.01mg/AH, can prolong 1-3 useful life doubly.
The utility model scope required for protection is not limited only to the described scope of above embodiment, and expanded microporous polytetra fluoroethylene-EPTEE filter 4 described in the utility model and palladium pearl 5 also can be loaded in the pressure relief valve 3, and this also belongs to the utility model scope required for protection.
Claims (2)
1, a kind of storage battery comprises casing (1), filling opening (2), and pressure relief valve (3) is characterized in that being equipped with in the filling opening (2) expanded microporous polytetra fluoroethylene-EPTEE filter (4) and palladium pearl (5).
2, storage battery according to claim 1 is characterized in that having gap (6) on the expanded microporous polytetra fluoroethylene-EPTEE filter (4), and the quantity of palladium pearl (5) is the 1-50 grain.
