Description
Technical Field
The invention belongs to the technical field of storage batteries, and relates to a manufacturing method of a lead-acid horizontal battery.
Background
Currently, chemical power sources used as power storage batteries for electric vehicles are: nickel metal hydride batteries, zinc air batteries, lithium ion/lithium polymer batteries, fuel cells and lead acid batteries, but to date none of the power cell technologies have matured to a point where the presence of other batteries is negligible. The lead-acid storage battery has the advantages of low price, mature technology, safety, reliability, abundant resources, recyclability and the like, but the traditional lead-acid storage battery as a power battery has a larger difference with other types of storage batteries on the key index of specific energy, so the lead-acid storage battery has to be technically innovated to possibly meet the requirements of electric vehicles, and the horizontal lead-cloth battery greatly improves the specific energy, specific power and cycle life of the battery due to the revolutionary change of the structure and the application of novel composite materials, thereby greatly improving the competitiveness of the lead-acid battery as the electric vehicle battery.
The horizontal battery has four technical characteristics:
1.1 light composite material technology: the lead net grid is a lead net woven by lead wires formed by coating pure lead (or lead alloy) on high-strength glass fibers through solid-state extrusion. The structure reduces the weight of the battery and improves the gravimetric energy.
1.2 horizontal bipolar structure; the positive and negative plates and the partition plates are horizontally staggered and stacked, except that the two ends are provided with unipolar plates, the rest are bipolar plates. This configuration also determines the busbars that must be used in conventional batteries, reducing the amount of lead used and, on the other hand, increasing the gravimetric energy of the battery.
1.3 unique battery case design and pressure frame construction; each monomer all has independent pressure frame during battery equipment, and the battery case is inside to be a whole body, and each face of battery case all has the constant head tank, and during the equipment, pressure frame's rib inserts the constant head tank of battery case, prevents that the battery from taking place the drunkenness in the impact vibrations environment inside, has improved the shock resistance of battery, has prolonged battery life.
1.4 full automation of the production process: the automatic plate coating line, the automatic mechanical arm assembly line, the automatic welding and detection line, the temperature compensation battery testing equipment and the like are all unique.
Secondly, the current situation: to date, there are no reliable horizontal battery products in bulk at home and abroad for the following reasons:
2.1 coating paste: because the lead cloth is thin, compared with the common grid coating plate, the lead cloth is easy to stretch and deform, and the coating is difficult. In addition, the positive and negative electrode lead pastes are coated on the bipolar plate grid at the same time, as shown in fig. 1, the positive and negative electrode lead pastes are respectively coated and filled at two ends of a piece of lead cloth, and a separation band of about 10mm is reserved in the middle without coating the lead paste. Because the lead-acid battery is very sensitive to the mixing of positive and negative lead pastes, only a 10mm isolation strip is enough to ensure that the positive and negative lead pastes are completely separated in the processes of coating, curing, drying, cleaning and the like of the polar plate.
2.2 terminal welding: the lead wire wall is too thin, lead and glass fiber are not infiltrated, and if the lead wire is improperly welded, the inner core is easily melted to cause insufficient welding, so that the qualified rate of the battery is low.
2.3 self-discharge: since no partition wall is provided between the cells, the self-discharge is large, reaching 10%/month. There may also be some reason that self-discharge may occur between some of the liquid film and the grid despite the use of a poor liquid design.
2.4 cycle life: the U.S. power company declared a horizontal battery cycle life of 800-900 weeks, but the actual test life was only 200-300 weeks.
