Lead accumulator, was technically constantly improved and has been developed by since G.Plante invention from 1859.Because lead accumulator has cheap, the advantage such as efficiency for charge-discharge is high, can adapt to load variations, stand heavy-current discharge, reliability and fail safe height, thereby, be widely used in all trades and professions.
At present, lead accumulator is widely used in the fields such as automobile, train, tractor, motorcycle, electric motor car and communication, power station, electric power conveying, instrument and meter, ups power and aircraft, tank, naval vessels, radar system.Along with the raising day by day of world energy sources expanding economy and living standards of the people, in secondary power supply used, lead accumulator had occupied the market share more than 85%.
Power lead-acid storage battery develops into today, and electric three-wheel is automobile-used, the automobile-used large capacity of electric motorcycle, high-power battery become consumer and manufacturer in the urgent need to.And concerning storage battery itself, what determine its capacity is more active matter quality, determines that high-power is can allow to discharge with larger discharging current.
At present, lead acid accumulator commonly used is that the cell by 6 single 2V voltages consists of through series connection, and pole plate commonly used is 4 positive battery pole plates and 5 negative battery pole plates, perhaps 5 positive battery pole plates and 6 negative battery pole plates.The negligible amounts of positive/negative plate, total like this polar board surface is long-pending smaller, and the guiding discharge electric current is little, and power is little.
If increase the quantity of positive/negative plate, can increase the total surface area of positive/negative plate, with the increase of surface area, the discharging current of battery increases, and namely the power of battery improves; Moreover, increase the quantity of positive/negative plate, can increase simultaneously the amount that is coated in the active material on positive/negative plate, namely increased the capacity of battery.
The utility model content
In prior art, the problem that the capacity of lead acid accumulator is little, power is lower, the utility model provides a kind of large capacity, high-power lead acid accumulator, comprise battery case, with some utmost point groups chamber, utmost point group is equipped with positive plate spaced apart and negative plate in the chamber in this battery case, between adjacent positive plate and negative plate with dividing plate, in each utmost point group chamber, positive plate quantity is 8~12, and negative plate quantity is Duoed one than the quantity of positive plate.
The pole plate of lead acid accumulator commonly used is 4 positive plates and 5 negative plates, and the total surface area of pole plate is smaller, and the guiding discharge electric current is little, and power is little.And the negligible amounts of positive/negative plate, the amount that is coated in the active material on positive/negative plate is less, causes the capacity of battery less.The utility model has increased the number of positive/negative plate, has increased the total surface area of pole plate, can carry out than heavy-current discharge, has namely improved the power of battery; The increase of the number of positive/negative plate simultaneously, the amount of the active material of coating increases thereupon, and the capacity of battery increases.
As preferably, positive plate quantity is 9, and negative plate quantity is 10.
Described battery case comprises box body and lid, and described utmost point group chamber is being distributed in box body of matrix form.
Described utmost point group chamber is six.Six utmost point group chambeies are divided into two rows along the battery case length direction, and three of every rows are being distributed in box body of matrix form.
The length of box body described in the utility model is 210~230 millimeters, and width is 160~175 millimeters, is highly 120~140 millimeters.
Further preferred, the length of described box body is 220 millimeters, and width is 166 millimeters, is highly 130 millimeters.
Dividing plate is as preventing the inertia spacer of both positive and negative polarity short circuit, and it need to possess good ionic conductivity, and with the exception of this, dividing plate must be insoluble in acid solution, and impurity content should be little, and preventing that impurity from dissolving in affects battery performance in electrolyte; Also needing has high porosity, so that acid solution is evenly distributed, and acid solution flows smooth and easy in acid filling and when changing into.Because lead acid accumulator generally all adopts sulfuric acid as electrolyte, so should select to have acid proof separator material, therefore preferred, described dividing plate is glass fibre separator.
Be width and the size highly that adapts to described box body, six utmost point group chambeies are divided into two rows along the battery case length direction, the twice of the width of namely just/negative plate is less than the width of box body, the height of just/negative plate is less than the height of box body, as preferably, the width of described positive plate and negative plate is 75 millimeters; The height of described positive plate and negative plate is 91 millimeters.
The utility model has increased the quantity of positive/negative plate, make the total surface area of positive/negative plate increase, surface area is larger, allow maximum discharge current value just larger, add high voltage, the maximum discharge power of permission increases substantially, and, the quantity of positive/negative plate increases, and the amount that is coated in accordingly the active material on positive/negative plate also increases, and namely the capacity of battery increases.
Compared with prior art, the utlity model has following beneficial effect:
(1) improve the specified discharge power of permission of battery more than 30%.
(2) high capacity cell can satisfy the demand of high-power electric tricycle or battery-operated motor cycle.
(3) require identical mileages of continuation, depth of discharge is shallow, greatly extends the useful life of storage battery.
(4) the static weight specific energy of this battery reaches 43Wh/kg, and the static volume specific energy reaches 120Wh/L.
