Description
Technical field
The application relates to battery technology field, particularly relates to a kind of single level battery.
Background technology
Traditional sealed lead acid battery, one of its shortcoming is: the side of being disposed vertically used by battery pole plates in the inner
Formula and the electrolyte stratification phenomena that causes；Electrolyte stratification phenomena, the i.e. polarization phenomena of concentration of electrolyte difference, this is battery capacity
Decline and the one of the main reasons of the lost of life.
By cell making process and the improvement of this body structure of battery, occur in that now a kind of horizon battery, level electricity
Pond is to be used the mode of horizontal positioned to gain the name by battery pole plates in the inner.Horizon battery is put due to its battery pole plates level
Put, thus the problem overcoming conventional batteries electrolyte stratification.The pole plate of horizon battery is horizontal quasi bipolar structure, and it is at lead
The half painting positive active material of web plate grid is as positive plate, and second half painting negative electrode active material at this lead fabric plate is negative pole
Plate, leaves the space of about 10mm between the positive negative active material of double polarity plate, with spraying Colophonium isolation, prevent short circuit.Level is double
Double polarity plate in polarity lead-acid battery is according to from left to right, and from top to bottom, the positive/negative plate on double polarity plate is staggered to be put
The order put is placed, and being the most all coated with by barrier film of every pole plate, assembles finally by some sheet materials and battery case.
After being completed, in addition it is also necessary to through acid filling, chemical conversion, and by filling wax, bipolar plates unit compartment space is filled, to increase electricity
The anti-shake performance in pond, reduces unit compartment acid solution and the vibration of acid gas, to reduce the self discharge amount of battery simultaneously.
Horizontal double pole lead-acid battery of the prior art, there is problems in that
1, being coated in respectively on same plate due to positive active substance and negative active material such as lead plaster, this causes weighing double
Pole plate gross weight and cannot distinguish accurately control unipolar plate weight, it is impossible to keep battery with two side terminals, when the positive and negative activity on coated plate
When material proportion deviation ratio is bigger, the deep discharge service life of battery can be had a strong impact on；
2, in cell production process, it is melted into again after acid filling, needs after chemical conversion to discharge acid more than needed, use
Placing the mode that nature flows out, inside battery particularly connects and has residual acid solution on the spongy lead between two pole groups.And work as acid discharge
Needing after completing to inject high-temperature liquid state paraffin, paraffin after cooled and solidified, forms contracting because expanding with heat and contract with cold in unit compartment in battery
Hole, makes unit compartment produce acid solution and the interface channel of acid gas, causes connection between cell to form micro cell and causes self discharge,
Affect battery with two side terminals；
3, internal element lattice string acid problem: such as, 12V horizon battery has 6 internal single lattice, internal generation during discharge and recharge
Acid gas, acid solution all can connect string lattice in several cells, cause reaction efficiency in 6 cells inconsistent and self discharge differs
Cause, affect battery with two side terminals；
4, existing level battery unit compartment seals by filling wax, and inside is unable to reach preferable sealing effectiveness, and battery is deposited
During putting, in battery 6 unit every self discharge because filling wax sealing effectiveness difference, unit compartment self discharge difference is relatively big, meeting
Battery consistency is produced large effect；
5, horizontal double pole battery is because of structure design reasons, it is impossible to produce larger capacity batteries.At Large Copacity application neck
Territory, need to use many Battery packs in parallel, but because of the inconsistent reason of horizontal double pole self-discharge of battery, cause it to be unable to reach great achievement
Pool-size life requirements.
