The status and development trend of Lead-acid battery industry (part 1)
Battery industry is another important component of the energy sector is the economic development of a new hot spot in 2006, the United States there are two top ten science and technology plan for the proposed battery , lead the industry Laptop battery acid, one third of total sales, and electricity, transport, development of information industries is closely tied to the truck automotive and other transportation and powerful system-wide uninterrupted power supply in the control of social production and business activities and human life, an essential product. The industry lead acid battery is the twenty-century and the first application of the most promising prospects of new green energy systems, while related to the implementation of national development strategies sustainable.
In recent years, lead-acid battery technology continues to grow, mature products. Structure progressively from the IBM ThinkPad T60 battery optimization and improvement, maintenance free batteries widely used, is still military, civilian transportation equipment, a device power supply important for our country become the world of big auto-producing countries play an important supporting role. VRLA batteries, gel batteries as backup power, large reserves of power components of heart, his production has become an important basis for economic development in the sex industry. Promising lead acid battery industry.
The main raw material for lead-acid batteries - lead repeated use recyclable, provided that the introduction of battery recycling waste related industrial policies, the right to direct the market, we can really solve the shortage of non-China Non-ferrous metals, lead pollution, resource and environmental problems a lot. Therefore, a correct understanding of the industry of storage Dell U4873 battery, the status quo, identify trends and effectively solve their own problems, is the recycling of resources and building a conservation-oriented society, is an effective way of scientific development in the national economy.
Firstly, the status quo of China’s lead-acid battery industry
Since its accession to the WTO, as well as the domestic industry and international battery, encourage manufacturers to increase investment in China, cause the rapid development of China-acid battery industry, the growth rate Annual over 30%. At the same time as the increasing demand of international market, China became the world’s largest exporter of lead acid batteries. Involve China, the acid hp 367759-001 battery technology and the gap between the international level was not evident, car batteries at international advanced level, use the power, the battery technology for electric bikes near the international advanced level.
After more than 20 years of development, maintenance free battery and sealed storage has achieved great success in technological advances to make lead-acid batteries, not only in transportation, military and national defense are widely used traditional areas, and is widely used in solar photovoltaics, wind power, communications power supply, power conversion and distribution, rail, maritime communications, starting, lighting, power, UPS power. Technological advances have contributed to the rapid development of industry stockpiles, making it one of the branches emerging future. However, because the lead, the main raw material-acid batteries - lead prices in the second half of 2004, a substantial increase, and continued to maintain a high price to run, lead-acid sony VGP-BPS2A battery drop-profit sector profit.
In recent years, along with changes in market demand, lead acid batteries continue to improve methods and processes of production, manufacture, scale, the specific energy battery, life cycle, the performance, consistency, use of safety and environmental protection continues to increase. With supply electric bicycle battery such as the development of technologies to high temperature drying is progressing rapidly. Generally believed that high temperature drying can increase the lifespan of the battery in recent years, and the ratio of negative additives also accumulated a large number of parameters, and identified a number of ordinary experiences. At home for other advanced technologies, such as liquidation of battery type, bipolar type, thin plates, etc. are still at the research stage, there is no mass production.
Status report of our patented technology, the toshiba PA3191U-2BRS battery industry in recent years, the overall line of development of defense technology is the improvement of the battery structure and evolution of the battery. The foreign patents are primarily related to cash thin bipolar plates lead acid battery, using the module structure of cells and colloid electrolyte lead battery sealed. Therefore, our proprietary technology with foreign countries is lagging a bit.
Secondly, lead-acid battery industry, the status quo and problems of environmental protection
After years of construction and development of China’s lead-acid battery industry has been primarily consisting of the system and showed trends of rapid development, environmental issues also made a breakthrough, at present, fumes of lead from China and the dust, sulfuric acid mist and methods of water treatment techniques and was essentially mature, medium and large lead acid battery manufacturers constantly increase the technological transformation efforts and modernizing process equipment commonly used in high efficiency cartridge precipitator replacement electrostatic dust-collector style, using a wet cleaning fumes of lead dust, with turbulent Ball sulfuric acid mist cleaning treatment fog absorption tower, flocculation reaction of lead-containing waste water treatment of acid technology to eliminate or reduce the impact of pollutants on the environment, producing a continuous improvement of working environment, most large and medium-sized manufacturing companies to achieve cleaner production, it is partly thanks to the certification of the National Environment.
However, for several reasons, the process of cell production of the pollution problem has not been well resolved, particularly in some of the many small and medium enterprises serious pollution problem in the production process: from Many manufacturers, small-scale, are more ecprice polluting, the uneven quality varies, some lack the environmental conditions of the factory workshop style rush into mass action, approximately one quarter of companies without approval Environmental Site of unauthorized construction, plant control of pollution are not complete, production is not strict measures of environmental protection and industrial safety and hygiene conditions, the operator and dangers to the ecological environment. Production permit system does not strictly own production, plant protection of the environment in respect of this point. Although our country since 2005, implementing the system of production permit, but because of the approval and implementation, there are problems and do not encourage manufacturers to achieve truly clean production, and many Manufacturers are not the legalization of Compliance (currently 930 companies were certified homes), causing serious environmental problems. Laws relating to the protection of the environment there is much more imperfect and not entirely satisfactory. Against polluting enterprises, protection of the environment and the fines and other ministries is limited, companies can not compare the social costs of pollution. In addition, the country does not specify protection for large and medium-sized policies apple M8403 battery manufacturers, and local departments of environmental protection is also for the management of small manufacturers of batteries, only the emphasis of regulation on businesses large and medium, reflecting firms’ costs of treatment of large and medium, monitoring costs, the “three simultaneous” evaluation fee, as a heavy burden.
