Largest batteries

It is known that the battery market has been in a continuous growth as evidenced by the increase in the number of portable applications that use batteries, especially electronic applications (see Table 1). However, there is no definitive authority reporting on world battery markets, and the majority of the marketing analysis in batteries are private reports specializing in a particular area. Therefore, the analysis presented in this section is only based on the reputed information available in the unrestricted literature, which is basically based on battery sales until 1997 (information for further years is not available in the public literature). Since Japan is one of the countries with the largest battery production in... 

Sony is number one worldwide in production of lithium-ion gel polymer batteries, especially the relatively small-sized (below 1 Ah) battery. Sanyo-GS (Japan) and Samsung SDI (Korea) also are producing this kind of battery. Recently, a Chinese manufacturer started to produce lithium-ion gel polymer battery. ATL, one of the largest battery manufacturers, is producing a polymer battery based on Bellcore technologies. However, those manufacturers still continue their production in the small-sized battery field. 

This section summarizes key observations from our direct investigations of lithium-ion battery field-failures, including work carried out with some of the largest battery and portable device manufacturers in the world. While confidentiahty restrictions prevent us from incorporating specific details of these safety incidents, we are able to highlight major observations and insights gained from this work, and from other sources. We have learned that ... 

Where intensive and continuous operation of a vehicle is involved, and the largest battery that can be accommodated is not capable of completing the vehicle s duties between recharges, it is actually necessary to calculate the total capacity required. 

The lead storage battery, the largest single user of lead and its compounds, is made possible by the high degree of reversibiUty, both chemical and physical, in the fundamental chemical reaction... 

Uses. The largest use of lithium metal is in the production of organometaUic alkyl and aryl lithium compounds by reactions of lithium dispersions with the corresponding organohaHdes. Lithium metal is also used in organic syntheses for preparations of alkoxides and organosilanes, as weU as for reductions. Other uses for the metal include fabricated lithium battery components and manufacture of lithium alloys. It is also used for production of lithium hydride and lithium nitride. 

California and Minnesota have placed restrictions on the disposal of fluorescent light tubes, which contain from 40—50 mg of mercury per tube, depending on size. After batteries, fluorescent lamps are the second largest contributor of mercury in soHd waste streams in the United States (3,14). A California law classifies the disposal of 25 or more fluorescent lamp tubes as hazardous waste. In Minnesota, all waste lamps generated from commercial sources are considered hazardous waste. Private homes are, however, exempt from the law (14). Other states have proposed similar regulations. Several companies have developed technologies for recovering mercury from spent lamps (14). 

Conversion of fused pentoxide to alloy additives is by far the largest use of vanadium compounds. Air-dried pentoxide, ammonium vanadate, and some fused pentoxide, representing ca 10% of primary vanadium production, are used as such, purified, or converted to other forms for catalytic, chemical, ceramic, or specialty appHcations. The dominant single use of vanadium chemicals is in catalysts (see Catalysis). Much less is consumed in ceramics and electronic gear, which are the other significant uses (see Batteries). Many of the numerous uses reported in the Hterature are speculative, proposed. 

By far, the largest appHcation of zinc powder is for solution purification in electrolytic zinc plants. This appHcation consumed an estimated 17,700 t of powder in 1980. Zinc powder is also used in primary batteries, frictional materials, spray metallizing, mechanical plating, and chemical formulations. 

The largest use of zinc chloride in the United States is in wood preservation, fluxes, and batteries (see Batteries). Zinc chloride solution dissolves vegetable fiber and is widely used in mercerizing cotton (qv), swelling fibers, as a mordant in dyeing, parchmentizing paper, etc (see Fibers, vegetable ... 

Industrial Consumption. The total consumption of primary antimony fell during the period from 1970 to 1986 (Table 3) because of the declining demand for antimony in most types of metallic uses. Since 1986, the demand for primary antimony in antimonial lead has increased, probably because of an increase in demand for starting—lighting—ignition (SLI) batteries. Total consumption in nonmetallic uses has remained stable. However, an increasing proportion of this is made up of flame retardant uses. Currendy, batteries and flame retardants are the two largest markets for antimony. 

The case is the largest portion of the container. The case is divided into compartments which hold the cell elements. The cores normally have a mud-rest area used to collect shed soHds from the battery plates and supply support to the element. Typical materials of constmction for the battery container are polypropylene, polycarbonate, SAN, ABS, and to a much lesser extent, hard mbber. The material used in fabrication depends on the battery s appHcation. Typical material selections include a polypropylene—ethylene copolymer for SLI batteries polystyrene for stationary batteries polycarbonate for large, single ceU standby power batteries and ABS for certain sealed lead—acid batteries. 

The largest outlet for the bituminous plastics has been for automobile battery boxes. Bituminous battery boxes do, however, have a susceptibility to electrical breakdown between the cells and in Europe their use has been mainly confined to the cheaper batteries installed initially in new cars. Bituminous compositions have also been used for toilet cisterns and to some extent for cheap containers. They are no longer important. 

The U.S. is the world s largest recycler of lead scrap and is able to meet about 72% of its total refined lead production needs from scrap recycling. The secondary lead industry consists of 16 companies that operate 23 battery breakers-smelters with capacities of between 10,000 and 120,000 t/yr five smaller operations with capacities between 6000 and 10,000 t/yr and 15 smaller plants that produce mainly specialty alloys for solders, brass and bronze ingots, and miscellaneous uses.
