Description
Technical field
The present invention relates to control valve formula lead accumulator.
Background technology
In recent years, more and more with the pole plate of net metal grid (expanded metal grid) as control valve formula lead accumulator.The net metal grid is: on lead alloy sheet (sheet) etc. many slots (slit) are intermittently be arranged in parallel, after the wire portion between slot is protruded in the about face of sheet (sheet), above-mentioned (sheet) stretched in the direction vertical with slot, be formed for keeping a plurality of diamond-shaped meshes (mesh) (with reference to Fig. 1) of active material thus.Because it is thinner that this kind net metal grid can make, therefore be better than traditional casting grid.Thereby, by the net metal grid being used for the pole plate of control valve formula lead accumulator, can realizing alleviating the weight of lead accumulator and cut down the use amount of pole plate with lead alloy.
But because the net metal grid is not provided with framework at the two ends of above-mentioned direction of extension and vertical direction, so the mesh of this part do not have closure, is open state (with reference to Fig. 1).In addition, when this kind net metal grid was used for pole plate, with discharging and recharging and the active material that expands can be especially be exposed to the outside from the inside of above-mentioned not closed mesh, the active material that exposes can contact with the pole plate of subtend around barrier film, thereby is short-circuited.
The words that are described in more detail, in the control valve formula lead accumulator, electrolyte be in the porousness active material that is included in anodal and negative pole and the barrier film that constitutes by fine glass mat (glass-mat) (nonwoven fabrics of fine glass fibre) in state time and remain in the battery.In the control valve formula lead accumulator of this kind structure, must keep the adherence at barrier film and above-mentioned the two poles of the earth, make electrolyte mobile smooth and easy between these parts.
Therefore, as shown in Figure 2, the positive pole that is made of the net metal grid and the pole plate 22,23 of negative pole dispose barrier film 21 alternately, therebetween and on the stacked pole plate group 20 who constitutes, and generally are applied in the pressure (group press) of barrier film 21 along about the 20kPa-60kPa of thickness direction compression.Thereby the pressure that is applied to the active material of the mesh inside that is filled in the net metal grid becomes big, and the active material of expansion is extruded the outside in mesh by above-mentioned pressure.
In addition, compare to trickle as stand-by power supply etc. as the control valve formula lead accumulator of the formula that recycles of the power supply of motor vehicle etc. and use (trickle use) formula, depth of discharge is very dark, and the frequency of being discharged fully is also bigger.Thereby, recycling in control valve the formula lead accumulator, particularly negative pole of formula, the expansion of above-mentioned active material is comparatively remarkable, and it is big that the possibility that is short-circuited also becomes.
In addition, because the decline of the battery capacity that this kind short circuit is caused is very rapid, therefore this moment, user's loss was also very big.That is the decline of the battery capacity slowly after, charge and discharge cycles repeats to a certain degree easily by the user cognition.In addition, this situation can more or less freelyly be detected by the passing of the discharge voltage of battery and the variation of internal resistance.Therefore, by judging remaining capacity by discharge voltage and internal resistance, the user can take to change appropriate measures such as battery before battery can't use.
But the rapid capacity that short circuit caused descends and can't carry out ex ante forecasting by above-mentioned the variation by discharge voltage passing and internal resistance.Therefore, the user can't take to change adequate measures such as battery in advance, and will face with the battery is the state that the machine of power supply can't use suddenly.Thereby the internal short-circuit that suppresses lead accumulator is the important technology problem that lead accumulator should solve.
Relevant therewith, for example open in the flat 10-40896 communique the spy, the barrier film of employed fine glass mat (glass-mat) and bag structure that the shape barrier film uses together that the synthetic resin fiber felt constitutes have been proposed usually.According to the lead accumulator of patent documentation 1 record,, can prevent the negative electrode active material that expands and the short circuit of positive plate by negative plate being taken in the above-mentioned bag shape barrier film.
Summary of the invention
But, in the lead accumulator of above-mentioned document record, owing to must increase bag shape barrier film newly, thereby can increase the number of components of battery.In addition, also must increase with the operation of the sheet material of synthetic resin fiber felt processing pouch with negative plate and take in operation in it, therefore can increase production cost of cells.
The present invention is in view of above-mentioned problem, and purpose provides and need not to increase number of components and manufacturing cost, can suppress by the expand control valve formula lead accumulator of caused short circuit of active material.
In order to solve above-mentioned problem, control valve formula lead accumulator of the present invention has the pole plate group, and this pole plate group is made of positive plate and negative plate interaction cascading and is provided with barrier film betwixt, and above-mentioned positive plate and negative plate contain the grid body that is useful on a plurality of mesh that keep active material, it is characterized in that
The grid body of above-mentioned at least negative plate is made of the net metal grid,
Distance between above-mentioned positive plate and the negative plate 1.20mm or more than, and
The reaction utilance of the active material in the mesh that remains in above-mentioned net metal grid of above-mentioned negative plate 32.0% or below.
In addition, be preferably, control valve formula lead accumulator of the present invention by increase and decrease total amount of contained electrolyte in above-mentioned active material and barrier film, is adjusted in the reaction utilance of above-mentioned active material in the above-mentioned scope.
According to control valve formula lead accumulator of the present invention, need not to increase number of components and manufacturing cost, can suppress because the caused short circuit of expansion of active material.
