Description
Technical field
The utility model relates to the battery technology field.
Background technology
Common batteries by multi-disc just is, alternate separating by dividing plate of negative plate is vertically placed in the cell groove, positive plate in each cell groove, negative plate connects together by the parallel connection welding respectively, single monomer is 2V, three or six monomer series-connected 6V or integral battery doors of 12V of together forming of groove, if need 36V or high voltage then need a plurality of batteries are connected on together with lead more outward, like this owing to the battery internal polar plate is vertically to place the battery electrolyte inside can produce layering and the concentration polarization phenomenon occurs, use middle and later periods positive plate top active material to produce super-charge super-discharge because of utilance is higher at battery, the easy softening and shedding of active material, the perishable distortion of grid, negative plate bottom causes battery failure because of the higher sulfation that is prone to of sour density.Because high-tension battery is to be connected together outward with lead by a plurality of 12V, 6V or 2V battery, contact resistance increases, the large current density voltage drop is big, the series connection monomer is prone to backward monomer more and causes battery life to shorten, it is big to connect inconvenience and potential safety hazard, floor space is big and be not easy to installation, and these defectives of common batteries have all seriously restricted the application of high-tension battery in new-energy automobile.And current development new-energy automobile is a brand-new notion and the problem that attracts people's eyeball, is just starting the tide of new-energy automobile both at home and abroad, if because storage battery can not be realized high voltage supply, then adopting storage battery is that the automobile of power will come to naught.
The utility model content
The utility model purpose is to lose the durable high voltage automobile power cell of polarization phenomena high life little, that droop loss is little, no electrolyte stratification causes for people provide a kind of compact conformation, roadlock.
The utility model comprises housing, porous barrier, anode pole plate, negative terminal pole plate, also comprises by even number alternate positive and negative and the continuous pole plate that is connected to form by torsion wire successively; By the porous barrier in the vertical direction even level is set in the housing, two ends in each odd-level are provided with anode pole plate and negative endplate plate respectively, the centre is provided with continuous pole plate, the pole plate that is arranged in described continuous pole plate two ends in each odd-level with at the anode pole plate at equivalent layer two ends and the heteropole extremely not each other of negative endplate plate, anode pole plate in this layer, negative terminal pole plate and continuous pole plate be horizontal arrangement respectively, and the junction between the anode pole plate in this layer, negative terminal pole plate and the continuous pole plate is separated by by the battery case plastic cleat respectively; The anode pole plate of each odd-level is arranged in the same side in the housing, the anode pole plate of each odd-level positive leading-out end line, the negative leading-out end line of the negative terminal pole plate of each odd-level formation in parallel of forming in parallel; In each even level, arrange continuous pole plate, the continuous pole plate horizontal arrangement in this layer, and the junction between the continuous pole plate in this layer is separated by by the battery case plastic cleat respectively; Vertical direction at the battery case plastic cleat is provided with the slit of passing through for continous way pole plate connection torsion wire.
The utility model can be realized directly connecting between groove owing to adopt continuous pole plate, shortens to link distance, reduces the roadlock loss, reduces droop loss, thereby realizes the new connected mode of the high integrated battery of volt; Because the pole plate horizontal positioned, favourable electrochemical reaction is fully carried out, and the concentration polarization phenomenon that does not have electrolyte stratification to cause does not have the anxiety of active material avalanche on the pole plate, compresses naturally, and it is constant that compression ratio keeps from start to finish.The pole plate cross-directional length can according to how much voltage of design needs, just by how many decisions of continous way polar plate number; As 36 volts be 2 * 18=36 sheet, 18 co-continuous pole plate horizontal positioned; Battery terminal voltage is 36 volts.Vertical direction stacks the number of plies decision battery capacity of pole plate, and the heap base pole plate number of plies is many more, and battery capacity is just big more, according to battery capacity design pole plate capacity, obtains the number of plies again, needs 60Ah as battery capacity, and monolithic pole plate capacity is 10Ah, and it is 6 layers that pole plate stacks the number of plies.So the utility model can be realized high pressure output, for storage battery is opened wider space in the application of automotive field.
