Description
Technical field
The application is related to battery technology field, more particularly to a kind of single level battery and its manufacture method.
Background technology
Traditional sealed lead acid battery, one of its shortcoming is：By the vertical of battery pole plates use in the inner
Electrolyte stratification phenomena caused by modes of emplacement；The polarization of electrolyte stratification phenomena, i.e. concentration of electrolyte difference
Phenomenon, this is the one of the main reasons of battery capacity decline and the lost of life.
By the improvement of this body structure of cell making process and battery, a kind of horizon battery is occurred in that now,
Horizon battery is due to that the battery pole plates in it are gained the name by the way of horizontal positioned.Horizon battery is due to it
Battery pole plates horizontal positioned, thus the problem of overcome conventional batteries electrolyte stratification.The pole plate of horizon battery
For horizontal quasi bipolar structure, it applies positive active material as positive plate in the half of lead fabric plate, herein
Second half of lead fabric plate applies negative electrode active material for negative plate, is stayed between the positive negative active material of double polarity plate
There is about 10mm space, isolated with spraying pitch, prevent short circuit.It is double in horizontal double pole lead-acid battery
Polarity pole plate is according to from left to right, from top to bottom, the order that the positive/negative plate on double polarity plate is staggeredly placed
Place, and every pole plate is coated by barrier film up and down, is assembled finally by some sheet materials and battery case
Come.After being completed, in addition it is also necessary to by acid filling, chemical conversion, and it is by filling wax that bipolar plates unit compartment is empty
Gap is filled, to increase the anti-shake performance of battery, while unit compartment acid solution and the vibration of acid gas are reduced, with
Reduce the self discharge amount of battery.
, there is problems with horizontal double pole lead-acid battery of the prior art：
1st, because positive active material and negative active material such as lead plaster are coated on same plate respectively, this causes can only
Weigh bipolar plates gross weight and can not accurately control unipolar plate weight respectively, it is impossible to keep battery with two side terminals, when
Positive negative active material proportional jitter on coated plate than it is larger when, the deep discharge that can have a strong impact on battery uses the longevity
Life；
2nd, in cell production process, it is melted into again after acid filling, needs to discharge acid more than needed after chemical conversion,
By the way of slant setting flows out naturally, inside battery is particularly connected to be had on the spongy lead between two pole groups
Remain acid solution.And need to inject high-temperature liquid state paraffin after the completion of the acid discharge, paraffin in battery after cooled and solidified,
Because expanding with heat and contract with cold in unit compartment formation shrinkage cavity, unit compartment is produced the interface channel of acid solution and acid gas, make
Forming micro cell into connection between cell causes self discharge, influences battery with two side terminals；
3rd, the sour problem of internal element lattice string：Such as, 12V horizon batteries have 6 internal single lattices, during discharge and recharge
The acid gas of inside generation, acid solution can all connect string lattice in several cells, cause reaction in 6 cells
Efficiency is inconsistent and self discharge is inconsistent, influences battery with two side terminals；
4th, existing level battery unit compartment is sealed by filling wax, and inside is unable to reach preferable sealing effectiveness,
During battery storing, in battery 6 units every self discharge because fill wax sealing effectiveness difference, unit compartment
Self discharge difference is larger, can produce large effect to battery consistency；
5th, horizontal double pole battery is because of structure design reason, it is impossible to produce larger capacity batteries.In Large Copacity
Application field, need to use multigroup cell parallel, but because of the inconsistent reason of horizontal double pole self-discharge of battery,
It is caused to be unable to reach great achievement pool-size life requirements.
