First post by: www.laptop-battery-stores.com

Recently, 36 journalists from Toshiba PA3285U-1BRS Battery the National University of Science and Technology set up a network of colleges and universities in China was informed that from Tsinghua University and other units from the experts last few years, proven by the repeated "level of lead-acid battery recovery technology" has entered the promotion stage of industrialization. Experts believe that, with the further promotion of the technology is expected to fundamentally the management of used batteries environment.
In all types of batteries, lead-acid batteries the largest share, according to statistics, about the secondary battery market, according to the 75%. Lead-acid batteries are widely used in automotive, communications, finance, electricity, railways, computers, switchboard, radio and television, forklifts, battery car, aviation, marine, military, mining, emergency lights, electric vehicles as well as other trades. "Lead-acid battery recovery technology" can be used on all types of lead-acid batteries (including domestic and imported) to recover the activation Toshiba PA3191U-1BRS Battery processing, especially for communications, finance, electric power industries fixed battery pack has been detected through the Ministry of Information Industry. At present, the technology has been in Heilongjiang, Zhejiang and other areas of the telecommunications sector, Shandong and other regions of the UPS manufacturers, Gansu and other regions of the power system to carry out many experiments and trial-related products industry has been production.
Existing lead-acid batteries of various products, whether domestic or imported, there is such a worldwide problem: the use of period usually have a charge on the difficulties, the capacity of lower self-discharge and even lead to a serious end-of-life failure, can not be used. The reason why lead-acid batteries have the above problems, and ultimately can be attributed to the repeated charging and discharging of the electrochemical reaction of "curing irreversible", when the accumulation of this phenomenon to a certain extent, this would lead to the loss of activity of the battery plate and can not be used . And "Super recovery of lead-acid battery technology" by measuring the battery state, into a dedicated activator, a reasonable standard Toshiba PA3166U-1BRS Battery set by means of charge-discharge, will change the composition and the nature of dielectric, ion channels open, and fully release and intensification of the original active substance, its recovery and have the electrochemical capacity of more. After recovery of the lead-acid batteries renewable, it will completely eradicate the "curing irreversible."
Waste of the environmental pollution caused by the battery has become the world’s problems. 1, a bad battery in the ground to make 1 square meter of soil loss of the use of permanent value; a button battery 600 tons of water can be contaminated, a person’s life is equivalent to the amount of drinking water. In Europe and the United States and other developed countries make full use of economic levers, so that the rate of general to achieve more than 50%. However, in our country, for the recycling of used batteries is also unsatisfactory. It is known for its harm is not enough, coupled with the appropriate policies and economic interests building system has not improved, the recovery rate of used batteries is relatively low. Recycling used batteries to work better in Shanghai as an example, since 1998 to start the recycling of used batteries, by the end of the first half of 2002, a total recovery of 175 tons of scrap batteries, which is 4 years in the city of 12,000 tons Waste production battery compared gap. China more than 5000 each year about 10,000, more than 300,000 tons of spent lead-acid batteries, but the whole collection in a state of disorder, large quantities of sulfuric acid by inverted arbitrary small Toshiba Laptop Battery traders, often because of lead waste handling or custody of misconduct abandoned the place, not only the serious pollution of soil and water sources, often directly endanger human health, is the most dangerous one of solid waste.
On the other hand, current end-of-life of lead-acid batteries, if not by mechanical damage, in normal use, the vast majority of aging or end-of-life battery can be effectively restored, can not be restored only 10%. Therefore, this "super-recovery of lead-acid battery technology" is being promoted, many will re-used lead-acid batteries "posts", a timely and effective manner to solve the battery problem.
In addition to the tremendous environmental value, which also contains a huge market. In 2002, domestic production on lead-acid batteries up to 3,000 million kilowatt hours and a value of nearly 80 billion yuan, and each year to grow at a rate of 30%. At the same time, according to estimates, the use of "super-recovery of lead-acid battery technology," the recovery of used batteries, the average cost to buy a new battery less than 1 / 4, which will save users a lot of money. With the industrialization of the technology promotion, an annual production value of up to several billion dollars to start the green industry was born.
October 9, 2003, State Environmental Protection Administration and National Development and Reform Laptop Battery Commission, Ministry of Construction, Ministry of Science and Technology, Ministry of Commerce jointly issued the “Waste Battery pollution control technology policy”, the technology policy as a guiding document, since the release from the date of implementation.
The technology policy applies to the classification of batteries, collection, transportation, utilization, storage and disposal of the whole process of dealing with pollution control technology options, the guidance of the corresponding facilities planning, project, site selection, construction, operation and management, and guide the relevant environmental protection industries. According to the type of battery and the main cause of pollution in general can be divided into a battery and secondary battery. Including a zinc battery - batteries and alkaline manganese dioxide zinc - manganese dioxide battery. Zinc - manganese dioxide battery into the battery and cardboard paste-type battery. Alkaline zinc - manganese dioxide batteries, including alkaline manganese batteries, button alkaline manganese batteries and rechargeable alkaline manganese dioxide batteries. Secondary batteries, including rechargeable batteries and a small lead-acid batteries. There are small secondary Toshiba PA3331U-1BRS Battery of nickel cadmium batteries, nickel hydrogen batteries and lithium-ion battery, in addition to motive power batteries, fuel cells, solar cells, nickel-zinc battery, such as metal-air battery.
Pollution prevention and control of waste batteries is the principle of process control, to avoid the transfer of secondary pollution and pollution. This is a common international waste management and pollution control cell line of thought, combined with the pollution features of our batteries and the actual situation of technical policy for the control of waste battery cell to follow the product life-cycle analysis of the basic principles of management of the whole process and pollutants total control of the overall technical principles. Focused, the principles of classification control. Spent batteries are solid waste, which is more harmful to the environment of hazardous waste are required to adopt more rigorous management of waste batteries is dangerous to attribute to determine batteries focus of environmental management.
According to the definition of hazardous waste characteristics, the management Toshiba PA3098U-1BRS Battery practices and the results of experiments that nickel-cadmium battery waste, waste mercury-containing batteries and waste lead-acid batteries are hazardous waste and general waste alkaline manganese batteries and manganese dioxide batteries are not hazardous waste , in particular, have reached a non-mercury-based batteries. Waste pollution control technology battery line, and technology policy in accordance with the production and use of batteries, waste battery collection, transportation, storage, treatment and disposal and recycling of the order of, respectively, route guidance technology requirements. Request from the production gradually increase the proportion of alkaline manganese batteries, the phasing out of battery paste; the development of lithium-ion batteries and Ni-MH battery rechargeable batteries, such as the production, as well as the ultimate alternative to the civilian market in the Ni-Cd battery out. To promote effective waste battery recycling and disposal, technology policy on the battery logo put forward specific demands. Batteries in accordance with solid waste in the different treatment of the pollution characteristics and possible new technical policies and regulations: in the burning of solid waste and composting to deal with the cities and regions should carry out waste separation on the collection, to avoid all kinds of waste battery life with garbage into the waste incineration plant and household waste fermentation plant; the prohibition on the collection of a variety of incineration of waste batteries. China’s cities and regions of the vast majority of waste disposal is landfill, you can waste time with Toshiba PA3084U-1BRS Battery and solid waste landfill.
