Description
Technical field
The utility model patent relates to a kind of lead acid accumulator, refers in particular to a kind of lead acid accumulator that the demarcation strip of absorption lead powder is set.
Background technology
Lead-acid battery has had the history in more than 100 year, has dependable performance, mature production technology, and than Ni-MH battery and lithium battery low cost and other advantages, the present electric bicycle overwhelming majority adopts the sealing-type lead-acid battery.The sealing-type lead-acid battery is with just, and the negative plate interfolded is arranged in the battery case, isolates with insulating barrier between the positive/negative plate, and in electrolyte was filled with battery case, the lead on electrolyte and the positive/negative plate carried out chemical reaction.When battery charges, just becoming lead sulfate, the lead on the negative two-plate discharges the sulfuric acid composition that is fixed therein in the electrolyte, becomes respectively lead and lead oxide, and the sulfuric acid concentration in the electrolyte is constantly increased, and voltage rises, the savings energy; During discharge, lead oxide in the positive plate and the lead on the negative plate and the sulfuric acid in the electrolyte react and become lead sulfate, sulfuric acid concentration in the electrolyte is constantly reduced, so that energy reduces, battery is externally exported energy, therefore the cycle charge-discharge of battery is the process that electric energy and chemical energy are constantly changed, and finally realizes storage and the release of energy.Be to improve the capacitance of storage of lead-acid battery, two surfaces of positive/negative plate are all made coarse and with the surface of grid, are made pole plate store more lead in the volume of minimum usually.But lead-acid battery makes the part lead powder just be adsorbed on, on the insulating barrier between the negative plate after repeatedly discharging and recharging inevitably, and just, the rough surface of negative plate also easily causes the breakage of insulating barrier, so all just can cause, the short circuit of negative plate, just make, negative plate produces a large amount of heats, makes electrolyte dry gradually, and burn pole plate, thereby cause battery capacity to reduce even inefficacy, battery is short, and the lead-acid battery ex factory pass rate is low.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to make, low cost of manufacture, can adsorb lead powder, the lead-acid battery of long service life.
The utility model is realized with following technical scheme: a kind of lead acid accumulator that the demarcation strip of absorption lead powder is set, be included in a plurality of monoblock battery cases that space and combination are set each other of adjacency and 1 cell through lid that shares that the peristome of described monoblock battery case is sealed, described each monoblock battery case has a plurality of battery chambers that separated by the next door, in described each battery chamber, accommodate the pole plate group, the pole plate group is by being consisted of by demarcation strip stacked positive plate and negative plate, positive plate and the negative plate respectively connector by separately are connected with negative electrode with positive electrode, wherein, described demarcation strip comprises the insulating barrier with adsorption capacity and lays the aperture less than the insulation filter plate of 1.5um, and the peripheral size of insulating barrier and insulation filter plate is greater than the peripheral size of positive plate and negative plate.
Further, described insulating barrier is ultra-fine fibre glass, and insulating barrier comprises two-layer at least.
Further, described insulation filter plate is PE filter plate or PC filter plate, and the insulation filter plate is arranged between two insulating barriers.
Adopt technique scheme, the beneficial effects of the utility model are:
The utility model is provided with insulating barrier and insulation filter plate between positive plate and negative plate, therefore lead acid accumulator is in the process that discharges and recharges, insulating barrier has good adsorption capacity, make electrolyte fully be adsorbed on the insulating barrier, to guarantee capacitance of storage, even the part lead powder is adsorbed on the insulating barrier, because the insulation filter plate just is located at, between the negative plate, therefore the insulation filter plate only can make electrolyte pass through, and lead powder is stopped, even if just, it is damaged that insulating barrier occurs in the rough surface of negative plate, can both just prevent by the insulation filter plate, the short circuit of negative plate, solved for a long time lead acid accumulator is adsorbed on the problem that insulating barrier causes the positive/negative plate short circuit because of lead powder in charge and discharge process, greatly alleviate simultaneously the loss of electrolyte, effectively improved battery.The utility model is because the demarcation strip that only arranges between positive/negative plate comprises insulating barrier and insulation filter plate, and simple in structure, easy to make, cost is low, can significantly improve the ex factory pass rate of lead acid accumulator.
