Battery Production Equipment

Advanced and Innovative SP500 Frame brushing machine LWFBM-1 As they are inexpensive compared to newer technologies, lead–acid batteries are widely used even when surge current is not important and other designs could provide higher energy densities. In 1999 lead–acid battery sales accounted for 40–45% of the value from batteries sold worldwide (excluding China and Russia), equivalent to a manufacturing market value of about $15 billion. The lead–acid battery is the earliest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, its ability to supply high surge currents means that the cells have a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by starter motors. Large-format lead–acid designs are widely used for storage in backup power supplies in cell phone towers, high-availability settings like hospitals, and stand-alone power systems. For these roles, modified versions of the standard cell may be used to improve storage times and reduce maintenance requirements. Gel-cells and absorbed glass-mat batteries are common in these roles, collectively known as VRLA (valve-regulated lead–acid) batteries. In the charged state, the chemical energy of the battery is stored in the potential difference between the pure lead at the negative side and the PbO2 on the positive side, plus the aqueous sulfuric acid. The electrical energy produced by a discharging lead–acid battery can be attributed to the energy released when the strong chemical bonds of water (H2O) molecules are formed from H+ ions of the acid and O2− ions of PbO2.Conversely, during charging, the battery acts as a water-splitting device. Construction Plates The lead–acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté's design, the positive and negative plates were formed of two spirals of lead foil, separated with a sheet of cloth and coiled up. The cells initially had low capacity, so a slow process of "forming" was required to corrode the lead foils, creating lead dioxide on the plates and roughening them to increase surface area. Initially this process used electricity from primary batteries; when generators became available after 1870, the cost of producing batteries greatly declined.Planté plates are still used in some stationary applications, where the plates are mechanically grooved to increase their surface area. The grid developed by Faure was of pure lead with connecting rods of lead at right angles. In contrast, present-day grids are structured for improved mechanical strength and improved current flow. In addition to different grid patterns (ideally, all points on the plate are equidistant from the power conductor), modern-day processes also apply one or two thin fibre-glass mats over the grid to distribute the weight more evenly. And while Faure had used pure lead for his grids, within a year (1881) these had been superseded by lead-antimony (8–12%) alloys to give the structures additional rigidity. However, high-antimony grids have higher hydrogen evolution (which also accelerates as the battery ages), and thus greater outgassing and higher maintenance costs. These issues were identified by U. B. Thomas and W. E. Haring at Bell Labs in the 1930s and eventually led to the development of lead-calcium grid alloys in 1935 for standby power batteries on the U.S. telephone network. Related research led to the development of lead-selenium grid alloys in Europe a few years later. Both lead-calcium and lead-selenium grid alloys still add antimony, albeit in much smaller quantities than the older high-antimony grids: lead-calcium grids have 4–6% antimony while lead-selenium grids have 1–2%. These metallurgical improvements give the grid more strength, which allows it carry more weight, i.e. more active material, and so the plates can be thicker, which in turn contributes to battery lifespan since there is more material available to shed before the battery becomes unusable. High-antimony alloy grids are still used in batteries intended for frequent cycling, e.g. in motor-starting applications where frequent expansion/contraction of the plates needs to be compensated for, but where outgassing is not significant since charge currents remain low. Since the 1950s, batteries designed for infrequent cycling applications (e.g., standby power batteries) increasingly have lead-calcium or lead-selenium alloy grids since these have less hydrogen evolution and thus lower maintenance overhead. Lead-calcium alloy grids are cheaper to manufacture (the cells thus have lower up-front costs), and have a lower self-discharge rate, and lower watering requirements, but have slightly poorer conductivity, are mechanically weaker (and thus require more antimony to compensate), and are more strongly subject to corrosion (and thus a shorter lifespan) than cells with lead-selenium alloy grids. Absorbent Glass Mat (AGM) In the absorbent glass mat design, or AGM for short, the separators between the plates are replaced by a glass fibre mat soaked in electrolyte. There is only enough electrolyte in the mat to keep it wet, and if the Advanced and Innovative SP500 Frame brushing machine is punctured the electrolyte will not flow out of the mats.   Principally the purpose of replacing liquid electrolyte in a flooded Advanced and Innovative SP500 Frame brushing machine with a semi-saturated fiberglass mat is to substantially increase the gas transport through the separator; hydrogen or oxygen gas produced during overcharge or charge is able to freely pass through the glass mat and reduce or oxidize the opposing plate respectively. In a flooded cell the bubbles of gas float to the top of the battery and are lost to the atmosphere.This mechanism for the gas produced to recombine and the additional benefit of a semi-saturated cell providing no substantial leakage of electrolyte upon physical puncture of the Advanced and Innovative SP500 Frame brushing machine case allows the battery to be completely sealed, which makes them useful in portable devices and similar roles. Additionally the battery can be installed in any orientation, though if it is installed upside down then acid may be blown out through the over pressure vent. To reduce the water loss rate calcium is alloyed with the plates, however gas build-up remains a problem when the Advanced and Innovative SP500 Frame brushing machine is deeply or rapidly charged or discharged. To prevent over-pressurization of the Advanced and Innovative SP500 Frame brushing machine casing, AGM batteries include a one-way blow-off valve, and are often known as "valve-regulated lead–acid", or VRLA, designs. Another advantage to the AGM design is that the electrolyte becomes the separator material, and mechanically strong. This allows the plate stack to be compressed together in the Advanced and Innovative SP500 Frame brushing machine shell, slightly increasing energy density compared to liquid or gel versions. AGM batteries often show a characteristic "bulging" in their shells when built in common rectangular shapes, due to the expansion of the positive plates. The mat also prevents the vertical motion of the electrolyte within the Advanced and Innovative SP500 Frame brushing machine. When a normal wet cell is stored in a discharged state, the heavier acid molecules tend to settle to the bottom of the Advanced and Innovative SP500 Frame brushing machine, causing the electrolyte to stratify. When the battery is then used, the majority of the current flows only in this area, and the bottom of the plates tend to wear out rapidly. Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine   Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine   This is one of the reasons a conventional car Advanced and Innovative SP500 Frame brushing machine can be ruined by leaving it stored for a long period and then used and recharged. The mat significantly prevents this stratification, eliminating the need to periodically shake the batteries, boil them, or run an "equalization charge" through them to mix the electrolyte. Stratification also causes the upper layers of the battery to become almost completely water, which can freeze in cold weather, AGMs are significantly less susceptible to damage due to low-temperature use. While AGM cells do not permit watering (typically it is impossible to add water without drilling a hole in the Advanced and Innovative SP500 Frame brushing machine), their recombination process is fundamentally limited by the usual chemical processes. Hydrogen gas will even diffuse right through the plastic case itself. Some have found that it is profitable to add water to an AGM battery, but this must be done slowly to allow for the water to mix via diffusion throughout the Advanced and Innovative SP500 Frame brushing machine. When a Advanced and Innovative SP500 Frame brushing machine loses water, its acid concentration increases, increasing the corrosion rate of the plates significantly. AGM cells already have a high acid content in an attempt to lower the water loss rate and increase standby voltage, and this brings about shorter life compared to a lead-antimony flooded battery. If the open circuit voltage of AGM cells is significantly higher than 2.093 volts, or 12.56 V for a 12 V battery, then it has a higher acid content than a flooded cell; while this is normal for an AGM battery, it is not desirable for long life. Specially designed deep-cycle Advanced and Innovative SP500 Frame brushing machine are much less susceptible to degradation due to cycling, and are required for applications where the Advanced and Innovative SP500 Frame brushing machine are regularly discharged, such as photovoltaic systems, electric vehicles (forklift, golf cart, electric cars, and others) and uninterruptible power supplies. These batteries have thicker plates that can deliver less peak current, but can withstand frequent discharging. Some Advanced and Innovative SP500 Frame brushing machine are designed as a compromise between starter (high-current) and deep cycle. They are able to be discharged to a greater degree than automotive batteries, but less so than deep-cycle batteries. They may be referred to as "marine/motorhome" batteries, or "leisure batteries". The capacity of a lead acid battery is not a fixed quantity but varies according to how quickly it is discharged. The empirical relationship between discharge rate and capacity is known as Peukert's law. When a battery is charged or discharged, only the reacting chemicals, which are at the interface between the electrodes and the electrolyte, are initially affected. With time, the charge stored in the chemicals at the interface, often called "interface charge" or "surface charge", spreads by diffusion of these chemicals throughout the volume of the active material. Most of the world's lead–acid batteries are automobile starting, lighting, and ignition (SLI) batteries, with an estimated 320 million units shipped in 1999. In 1992 about 3 million tons of lead were used in the manufacture of batteries. Wet cell stand-by (stationary) batteries designed for deep discharge are commonly used in large backup power supplies for telephone and computer centres, grid energy storage, and off-grid household electric power systems. Lead–acid batteries are used in emergency lighting and to power sump pumps in case of power failure. Traction (propulsion) batteries are used in golf carts and other battery electric vehicles. Large lead–acid batteries are also used to power the electric motors in diesel-electric (conventional) submarines when submerged, and are used as emergency power on nuclear submarines as well. Valve-regulated lead–acid batteries cannot spill their electrolyte. They are used in back-up power supplies for alarm and smaller computer systems (particularly in uninterruptible power supplies; UPS) and for electric scooters, electric wheelchairs, electrified bicycles, marine applications, battery electric vehicles or micro hybrid vehicles, and motorcycles. Many electric forklifts use lead–acid batteries, where the weight is used as part of a counterweight. Lead–acid batteries were used to supply the filament (heater) voltage, with 2 V common in early vacuum tube (valve) radio receivers. Portable batteries for miners' cap lamps headlamps typically have two or three cells.   Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine Advanced and Innovative SP500 Frame brushing machine
