    Gradient pattern of Secondary Lead Industry in China

    Secondary Lead Industry has obvious advantages of resources and environmental protection in the relevant battery industrial policies of the correct guidance, can lead an effective solution to our shortage of resources, lead pollution is serious and many other issues. Last 5 years, standardized Secondary Lead Industry-related policies and regulations promulgated one after another. January 1, 2003, “The People’s Republic of China Cleaner Production Promotion Law” came into force, its Secondary Lead Production in protecting and improving the production environment, ecological environment has obvious results.

    In the same year in October, “Waste Battery Pollution Prevention and Control Technology Policy,” published it clear that the waste lead-acid battery build the collection, transportation, dismantling, Secondary Lead Enterprise shall obtain hazardous waste operation license may operate or run after. However, this policy is the guiding document for the industry at that time did not produce the pattern of substantial impact. April 1, 2005, “The People’s Republic of China Solid Waste Pollution Prevention Law” was promulgated, but it does not have regulations, implementing rules, management practices, the less feasible.
      
    In the Secondary Lead the rapid development of the industry, China’s resources and environmental issues are also changing, with “resource recovery, reduction, reproduction” as the core concept of circular economy gradually regenerated lead the industry to be reflected in the policy making process. In 2007, a Secondary Lead Industry Development of China’s “watershed.” 
     
    In addition to poor: apple laptop battery Industry access conditions
     
    China’s Secondary Lead enterprises to small-sized, low levels of industry as a whole, in a disorderly competition state. March 10, 2007 “issued by lead and zinc industry, access conditions” respectively from the production scale, technology and equipment, energy consumption, comprehensive utilization of resources, environmental protection, production safety and occupational hazards such as lead and zinc industry in terms of the conditions put forward a clear requirements, the requirements for Secondary Lead: Secondary Lead corporate annual production of the existing access to a scale larger than 1 million tons; transformation, expansion of Secondary Lead projects, each of size must be 2 million metric tons; New Secondary Lead projects, each of size must be greater than 5 million tons. To encourage mergers and acquisitions of small and medium-sized lead-smelting factory Secondary Lead and lead smelting furnace, or incidental to the consolidation of recycling regenerated lead. Lead recycling project capital ratio to reach 35% and above. New and existing Secondary Lead projects, lead scrap recovery, treatment must adopt advanced technology and equipment. There must be energy-saving measures to ensure compliance with the national energy consumption standards. Secondary Lead Smelting energy consumption per ton of lead should be less than 130 kilograms of standard coal, power consumption less than 100 kwh. New Secondary Lead business lead is greater than 97% of the total recovery of the existing Secondary Lead business lead is greater than 95% of the total recovery, smelting of lead content in Spoil less than 2%, waste water recycling utilization rate greater than 90%.

    “Lead and Zinc Industry access conditions” improved the Secondary Lead the introduction of entry threshold, will help improve the industrial level and industrial concentration, so that a large number of environmental non-compliance, technical process behind the serious waste of resources of small businesses Secondary Lead eliminated. 
     
    Supporting the superior: circular economy pilot projects
     
    In October 2005, the State Council agreed that the National Development and Reform Commission, the State Environmental Protection Administration, Science and Technology, Ministry of Finance, Ministry of Commerce, National Bureau of Statistics officially launched a joint national circular economy experiment. In key industries and key areas, industrial parks and provincial and municipal organizations of circular economy pilot projects. Been included in the first batch of pilot units of circular economy enterprises in Jiangsu Spring Hing Secondary Lead Alloy Group Co., Ltd. and Henan Yuguang Gold & Lead Group Co., Ltd.. In 2007, the second batch of pilot units of circular economy list, Hubei Jinyang Metallurgical Co., Ltd. and Anhui Jieshou fields of circular economy industrial park Bangshangyouming camp.
      
    It is learned that the first batch of pilot enterprises of circular economy energy consumption fell by 12.1%, non-ferrous metal scrap recycling the same amount of years, about 25% of annual production, in order to make a positive contribution to energy reduction. Through the circular economy pilot projects, all the social resources recycling system with a prototype. apple a1008 battery,apple a1175 battery.

    The use and maintenance of electric vehicle battery

    Welcome to battery shop

    1, battery depth of discharge cycles on the battery life of a great impact, it is because the deeper depth of discharge, the electrode expansion contraction the greater the positive electrode active material shedding more and thus lose their discharge characteristics, performance degradation, until the end of life. So, should try to avoid using the batteries depth of discharge, so that sufficient light put ground, the general situation should be done: apple laptop battery to discharge a depth of 50% -70% of the best on one charge.

    2, battery discharge to the termination voltage to continue to discharge (before discharge) would seriously impair the battery, it is because at this time can easily form a non-reversible sulfation, so that deterioration of charging ability to recover, or even beyond repair. Therefore, when used to prevent excessive battery discharge, “under-voltage protection” is a valid measure. “UV protection” measures are controlled by the electric vehicle controllers, but instruments and light electric vehicles such as electric power from controller, so electric locks, once started together on electricity, although the current is small, but If the long discharge, battery over-discharge occurs. Therefore, can not lock a long time, do not be turned apple a1175 off immediately.

    3, the charge current should be less than or equal to the battery charge current can be acceptable, otherwise, over charging of excess current generated by electrolysis of water will consume liquid too quickly and cause serious gassing phenomenon, a long time charge will change very difficult, due to charge as much as possible to prevent the overcharge. Regular charger manufacturers to ensure that the apple a1185  battery does not overcharge.

    4, lead-acid batteries in particular, fear of loss electric discharge, loss 3-7 days to place the battery power, there will be permanently damaged, so as soon as possible after the use of rechargeable batteries. For a long time do not use the battery, should be every 15 days to charge the apple powerbook g4 battery once the battery storage to compensate for power loss when the self-discharge.

    5, battery is running in the hot season, the main problem existed charge. Therefore, in the summer should be to minimize powerbook g4 15inch battery temperature to ensure good heat to prevent sun exposure after charging, and should stay away from heat. At low temperatures, the charge mainly in charge acceptance ability is poor, causing the battery charging less than the problem of electricity loss. Low-temperature thermal insulation should be taken when freezing measures, in particular charge should be placed in a warm environment, conducive to ensure adequate electricity, to prevent irreversible sulphation results in longer battery life.

    About Improving The Safety Of Lithium-Ion Batteries

    After recalls and fires involving Lithium-ion batteries, battery manufacturers and scientists have launched an intensive effort to improve the safety of these rechargeable power packs found in dozens of consumer electronics products, according to an article scheduled for the Dec. 17 issue of Chemical & Engineering News.

    In the article, C&EN Senior Editor Mitch Jacoby points out that fires and explosions involving Lithium-ion compaq evo n400c battery are rare, occurring in anywhere from one in 1 million to one in 10 million batteries, according to the best estimates. Still, these widely-publicized incidents have worried consumers and forced costly recalls of millions of batteries.

    Researchers in industry and academia do not fully understand why Lithium-ion compaq evo n410c battery sometimes catch fire or explode, Jacoby notes. Possible explanations include impurities that short circuit the batteries and yet unidentified reactions that underlie the problem.

    Nevertheless, researchers are exploring new battery materials, including components that generate less heat and reduce the risk of mishaps. Manufacturers are already selling or planning to sell safer Lithium-ion compaq evo n400 battery,compaq evo n410 battery,compaq evo n600 battery for power tools and electric vehicles, with more improvements on the way, according to the article.
