As everyone knows, lead acid accumulator can be used for back-up source and electrical source of power, purposes is widely had in fields such as communication, electric power, vehicle launch, vehicle traction, new forms of energy, the baseplate material of traditional lead acid accumulator uses rigid conductive material, its sealing technology is complicated, is difficult to produce in enormous quantities; The conduction of substrate and anticorrosion modification difficulty, battery life is generally shorter; Substrate weight is comparatively large, and cost is also higher, and the raising of specific capacity is less; Simultaneously, traditional lead acid accumulator needs to use plumbous part positive pole and negative pole to be welded respectively when making, the internal resistance of cell is larger, conductive area less, makes the performance of high current charge-discharge low, when the discharge and recharge of needs large discharge, need many group lead accumulators to work simultaneously, inconvenience is installed, also can increases installation footprint, unfavorable industrial production simultaneously.
Summary of the invention
For above-mentioned weak point of the prior art, the invention provides a kind of long service life, cost is lower, easy for installation, floor space is little bipolar lead-acid accumulator.
To achieve these goals, the invention provides following technical scheme: a kind of bipolar lead-acid accumulator, comprise battery case, cap and substrate, described substrate has polylith, spacing side by side is arranged in battery case, the substrate being positioned at two ends is set to battery plus-negative plate, described substrate is made primarily of flexible graphite material, positive and negative electrode lead plaster is provided with in described substrate both sides, between two adjacent substrate, be provided with insulation frame, in described insulation frame, be filled with the barrier film be made up of glass fibre, rubber or plastic septum.
As preferably, described substrate comprises flexible graphite material and is coated in the copper conductive layer on flexible graphite material surface, aluminium conductive layer, plumbous conductive layer or its composite conductive layers, is embedded in aluminium, copper, iron or fortifying fibre at described flexible graphite material.
As preferably, described bipolar lead-acid accumulator can be valve-control sealed bipolar lead-acid accumulator or open type bipolar lead-acid accumulator or colloid bipolar lead-acid accumulator.
As preferably, the barrier film that filled glass fiber or chemical fibre are made in described insulation frame is made as valve-control sealed bipolar lead-acid accumulator.
As preferably, the barrier film that filled plastics plate or rubber slab are made in described insulation frame is made as open type bipolar lead-acid accumulator or colloid bipolar lead-acid accumulator.
Can be found out by above technical scheme, the present invention contains multiple substrate, is together in series between inner single lattice, do not need to use plumbous part to be welded into respectively with negative pole by positive pole, thus save lead material consumption, simultaneously, because the internal resistance of cell reduces, the increasing of conductive area, the performance of high current charge-discharge is improved, and flexible graphite material selected by substrate in addition, its sealing technology is simpler, more easily produce in enormous quantities, simply, battery life is longer for the conduction of substrate and anticorrosion modification; Substrate weight is less, and the raising of specific capacity is comparatively large, and cost is lower, is suitable for applying.
