The development of secondary cell (usually said discharge and recharge, reusable battery) is very fast.In all secondary cells, lead acid accumulator, with advantages such as its stable performance, cheap, the recyclable recyclings of waste product, still occupies the leading position in secondary cell commercialization field at present.Since entering 21st century, the requirement of environmental protection is more and more higher, as the lead related in manufacturing process and industry sour, that may cause environmental pollution, how by technology, extend the useful life of battery, to reach the purpose of energy-saving and emission-reduction, this becomes the focus that whole lead acid accumulator industry is paid close attention to.
The factor that affects service life of lead accumulator is a lot, and under normal conditions, grid is one of most critical factor of the whole service life of lead accumulator of impact.Under sour environment, the anode plate grid of battery, no matter battery be in the situation that charging or static all can corrosion, under extreme case, at high temperature, the environment that overcharges, the positive grid of battery will be at the short time corrosion, even rupture and cause the performance of grid to reduce when the battery long-term work.Grid after corrosion can't loaded current, thereby makes pole plate lose the function of conduction, and the grid in battery pole plates can't normally conduct electricity, and the lead plaster on pole plate will soften fast, obscission, and finally causes the battery rapid failure.
Generally, the grid active component adds that by the frame of surrounding vertical and horizontal rib forms, and at the upper side frame of grid, is designed with the lug of one fixed width, and lug mainly plays a part to conflux and is connected with the external world.Generally, the frame cross section of common anode plate grid is hexagon, vertically with horizontal section of ribs, is " water chestnut " shape, and the sectional area of every rib is substantially equal.For conduction and the diversion function of giving full play to the grid lengthways of rod, generally when grid design, lengthways of rod is than horizontal rib thick (showing as the sectional area ratio transverse rod strip large), and the distance between lengthways of rod is less than the horizontal bar stripe pitch.Laterally with lengthways of rod be staggered to form " " the little grid of shape is used for carrying active material---lead plaster to square, in the charge and discharge process of battery, the electric current mainly frame by grid branches to rib and is delivered to lead plaster again, the rib of grid need to possess certain intensity simultaneously, bears lead plaster and because of the lead plaster volume, changes to the power of grid effect in charge and discharge process.
Use the battery of above-mentioned common assembling to use after 3～5 years, dissect the battery after losing efficacy, align grid and observe rear discovery, the lengthways of rod normal of grid, and near the obvious corrosion of the transverse rod strip of both sides frame, phenomenon of rupture, the battery particularly used under the cycle charge discharge electrical environment, above-mentioned phenomenon is more obvious, and the transverse rod strip the closer to the both sides frame, its extent of corrosion is more serious, and laterally the corrosion of rib causes whole battery charging and discharging hydraulic performance decline and finally causes whole battery failure.
In view of above-mentioned phenomenon and the analysis of causes, how by improving grid structure, design long-life anode plate grid, become lead acid accumulator production enterprise and be badly in need of the technology and the design problem that solve.
