Lead-acid batteries on the environment pollution

Lead-acid batteries on the environment pollution

Electric bicycle to the green environmental protection, light weight, in line with the purchasing power of China's working-class urban residents have been popular laptop battery, but such a convenient means of transport in many cities has been blocked. The reason is actually used hp batteries for electric bikes blame.

According to environmental experts, not emissions from electric bicycle, but it is lead-acid batteries used in the pollution of the environment is much more serious than automobile exhaust. Lead-acid batteries by the lead, sulfuric acid and some other metal and plastic components, waste battery acid contains high levels of lead, not only a serious indiscriminate discharge of contaminated soil and water, on the air, damaging the ecological balance, but also lead to human metabolism, areas such as reproductive and neurological diseases, the body once the excessive lead content, will lead to mental decline, induced by malignant tumors of children, and even death.

Data show that the electric bicycle, the lead-acid batteries are consumables, brand batteries use 1 ~ 2 years to be replaced, and some non-brand-name batteries to be replaced for six months. Conservative calculation, the general use of lead-acid batteries in large cities over 200,000, and the rapid growth momentum. To this end, a number of provinces and cities clear that environmental protection departments, the market for electric bikes, where the use of lead-acid maintenance-free batteries, all from production through distribution unit, a unified cross-production deal with; Where to buy a new battery must pay Back to waste the battery, or not to sell a new battery.

It is learned that the majority of electric bike stores sell pipe regardless of recovery, the recovery of batteries that store, and some are not shipped back to manufacturers, but sold the collection of waste. Lead-acid batteries have been taken when the waste scavengers sell a lot of toxic dumping of acid being seriously polluted the environment. Electric Bicycle manufacturers and dealers are not interested in on the battery recycling them? Electric bicycle manufacturers, a person in charge frankly, discarded lead-acid battery manufacturers for the production or valuable, but the heavier the battery, back to business of dangerous goods in accordance with the charges, each of the price of electric vehicles do not recycling enterprises to increase the cost of the last hundred dollars. Who is law-abiding operators who suffer, it is the manufacturers and dealers are not interested in root causes.

The face of a worsening pollution problem in lead-acid batteries, they have suggested that radical measures must be taken. Norms on the one hand, manufacturers, distributors of battery recycling, processing acts, on the other hand, the establishment of pollution in large cities Treatment Center. The only way to tackle pollution caused by lead-acid batteries, electric bicycles can be blocked from the fate.

Portable solid oxide fuel cells available in the United States

The United States before the successful development of portable solid oxide fuel cell (SOFC: Solid OxideFuelCell). To propane gas for fuel, a fuel filling each about 24-hour continuous power output of 50W. The battery in November 1, 2004 to 5 in San Antonio, Texas (SanAntonio) at the "FuelCell Seminar" on the public.

Fuel cells known as "Revolution50". The idea of fuel cells for such purposes as "soldiers equipped with the fuel supply, the portable rechargeable battery system, outdoor lighting and advertising systems, vending machines, and electric power tools and so on material supply, the portable rechargeable hp pb994a battery, hp nc6110 battery charging system , outdoor lighting and advertising systems, vending machines, and electric power tools and so on.

SOFC with high power generation efficiency, but also need to reach operating temperature of the high temperature 1000 ℃. NanoDynamics through ceramic materials in battery cell technology and design to increase R & D efforts can be relatively low in some of the 600 ℃ ~ 850 ℃ under the drive. Characteristics, the company said, "the battery unit of output power per unit area density of 1W/cm2. Units the energy density of weight 3000Wh/kg" (Blakely). Thin-film materials such as self-development of the company.

Dalian-tube solid oxide fuel cell development to make a breakthrough

Dalian the use of low-cost preparation of inorganic membrane technology successfully prepared tube solid oxide fuel cell, single-tube cell open circuit potential up to 1.0V above 800 ° C, 0.7V under more than 25W of output power. The tube-type cell research breakthrough for the development of solid oxide fuel cell power plant and the concentration of dispersed power plant has laid a foundation for key technologies.

Solid oxide fuel cell using natural gas, city gas, liquefied petroleum gas, biomass gasification gas as fuel, the fuel chemical energy into electricity efficiently. As a result of solid oxide fuel cell with fuel-rich, clean and efficient, can be characterized by cogeneration can be widely used in large-scale power plants, distributed power plants, power plants, such as family, is considered to change the future power plant technology.

Solid oxide fuel cell membrane electrode configuration of the main plate and tube. Tube-type battery has good stability, ease of amplification module, suitable for the establishment of power stations, but the electrolyte membrane electrode electrochemical vapor deposition in general (EVD) technology to prepare, cost expensive. Therefore, the development of low-cost tube-type membrane electrode manufacturing technology, the development of solid oxide fuel cell power plant is crucial.

Direction in the Chinese Academy of Sciences and Ministry of Science and Technology project, supported by cast in solid oxide fuel cell membrane electrode forming the base, electrolyte and cathode coating film coating technologies, such as the preparation made significant progress, the success of the preparation Φ8mmx500mm tube -based membrane electrode. At the same time, study and solve the single-tube flow cell and sealed set of technical issues, the battery is good for repetition priming, high reliability. In the tube during the preparation of membrane electrode, the use of low-cost preparation of inorganic membrane technology, abandoning the high-cost vapor deposition (CVD) and the EVD technology, a significant reduction in the tube of Preparation of the cost of hp nc6120 battery, hp nc6140 battery, battery type for the future of technology industries development and solid oxide fuel cell has laid a good practical use of the technology base.
