Background technology
The thin pole plate of pure lead is soft with its unique grid, the thin characteristic of pole plate is manufactured out winding type accumulator, has the operating pressure of high assembling pressure and Geng Gao, has reduced the dehydration of battery greatly.Compare the common lead acid accumulator and have more excellent high low temperature performance, have higher fail safe, advantages such as higher starting power, better quick charge capability.But influenced by the limitation of shell structure and traditional storage battery, positive/negative plate all has only a lug, Yi Bian cell batteries or the battery pack be made up of positive/negative plate all have only a positive pole and a negative pole to form.Electrokinetic cell as vehicle-mounted power, the influence of " bottleneck " when the specific power of battery and high-rate performance still are subjected to discharging, current imbalance and asymmetric when main cause storage battery self structure causes pole plate charging and discharge, the plate ear of pole plate is only in a side on one side, electric current during discharge all flows to one side that the plate ear is arranged, and when charging, finish the input of electric energy just the opposite, thereby storage battery large current charge and when discharge, lug just becomes " bottleneck ", has a strong impact on the charge efficiency and the discharge capability of battery.
Summary of the invention
The purpose of this utility model be exactly a kind of high-specific-power is provided at above-mentioned weak point and have extended cycle life, the twin-pole ear winding sealing valve-controlled lead-acid storage battery of low resistance, high compression and the management of more effective thermal runaway.
Technical solution of the present utility model is: a kind of twin-pole ear winding sealing valve-controlled lead-acid storage battery, comprise the tubular cell body, upper and lower cover body, positive and negative pole plate, positive and negative pole plate ear, barrier film, dividing plate and positive and negative electrode constitute, and it is characterized in that: be equipped with two electrodes on the described upper and lower cover body; The equal correspondence of positive and negative pole plate is provided with positive plate ear group or negative plate ear group; Positive electrode is connected with positive plate ear group through positive terminal, positive plate in these two electrodes, and negative electrode is connected with negative plate ear group through negative terminal, negative plate.
Two electrodes on upper cover body described in the technical solution of the present utility model or the lower cover are same sex electrodes; The single ender on the positive plate of correspondence or negative plate of positive plate ear group or negative plate ear group.Plate ear quantity is pressed two same sex electrode design of lid increases a plate ear than in the middle of the conventional coiled battery two plate ears more.
Two electrodes on upper cover body described in the technical solution of the present utility model or the lower cover are different in nature electrodes; Positive plate ear group and negative plate ear group are arranged on the both sides of positive plate or negative plate respectively.Plate ear quantity is pressed two different in nature electrode design of lid and over there than conventional coiled battery plate ear more and increase symmetrical plate ear.
Positive plate ear group described in the technical solution of the present utility model or negative plate ear group comprise 2-20 plate ear.
The utility model is owing to be equipped with two electrodes on upper and lower cover body, these two electrodes can be same sex electrodes, it also can be different in nature electrode, it is that positive plate ear group or a plurality of negative plate ear are negative plate ear group that the equal correspondence of positive and negative pole plate is provided with a plurality of positive plate ears, positive electrode is connected with positive plate ear group through positive terminal, positive plate in these two electrodes, negative electrode is connected with negative plate ear group through negative terminal, negative plate, thereby, can finally be combined into bipolar ear storage battery with the positive plate of inside and negative plate by the positive/negative plate of monolateral plate ear or bilateral plate ear.With two anodal in parallel, two negative pole parallel connections, to reach when discharging and recharging, the current balance type on the pole plate improves high current charge-discharge effectively during use, the energy density height, and high temperature performance is good, suitable heavy-current discharge.The utlity model has high-specific-power and have extended cycle life, the characteristics of low resistance, high compression and the management of more effective thermal runaway.The utility model is mainly used in the high field of charge efficiency height, specific energy height, specific power such as the lead acid accumulator in electric automobile field.
