German scientists made a new type of anion-cell materials

November 11, Freiburg, Germany, Institute of Chemistry, University of British Gock crossing after several years of research produced a new type of anion, can be used as durable and high-power battery materials.

Anion is negatively charged atoms or molecules, as a part of the electrolyte in the battery charge transport between electrodes. According to the German “Le Monde” recently reported that crossing a large one made of anionic charge density is very small, and the combination of weak cation, hence the name weakly coordinating anions. Such ion-wrapped with a layer of Teflon external.

Because of this anion attraction is small, and the electrolyte in the weak interaction of other components, thus making a highly conductive electrolyte can result in rapid delivery of high-intensity current of the battery.

In addition to high-power batteries for the manufacture of durable things, this new type of anion can also act as a catalyst to accelerate chemical reactions. It is not only stable, and easy to manufacture, low cost.

Beijing introduced electric bicycle battery recycling system of used methods

According to the China Bicycle Association, the relevant experts, the electric bicycle used by the lead-acid batteries, the main components are lead and sulfuric acid, usually a battery using a period of one year or so. At present, dealing with lead-acid battery technology has matured, but because of the use of electric bicycles TV towers, and how to spread of household batteries are collected for centralized disposal is a pressing need to address the problem.

In response, environmental protection, industry and commerce, public security departments have jointly issued a circular, lead-acid battery for electric bicycle products for registration, the implementation of catalog management, and those who registered in the directory of the battery products can be sold in Beijing.

Learned from the Beijing Municipal Bureau of Commerce and Industry is currently sold in Beijing in the region of electric bicycles and electric bicycles lead-acid battery should go to the registration of business and environmental protection departments, the implementation of content management. Only the vehicle performance in line with national standards, vehicle weight of not more than 40 kg, has a good foot function, and the statutory inspection by the state institutions sampling qualified products can be included in the directory. Industrial and commercial law enforcement agencies will begin the legal market for electric bikes regular sampling and testing does not meet the standards will be out of the market, manufacturing enterprises are responsible for the recall do not meet standards. Also, lead-acid battery electric bicycle manufacturers but also to provide a sound waste battery recycling program, point of sale to provide battery replacement and recycling of waste services, collection of waste batteries to have a business license of waste batteries the unit centrally.

It is reported that the annual environmental protection departments will be assessing the recovery rate of the enterprise for two consecutive years up to standard lead-acid battery products, we are no longer included in the directory, and can no longer be sold in Beijing. Beijing Municipal Environmental Protection Bureau of Solid Waste and Noise Management Branch, Cheng Xia, told reporters that municipal environmental protection bureau in the directory annual assessment of waste lead-acid battery recovery. According to Cheng Xia introduction, the general use of lead-acid battery electric bicycle. Abandoned if it is not the safe disposal of batteries, it is easy to environmental pollution. Electric bicycle ban, to a certain extent will environmental safety risks. The past, some small vendors without permission of the used batteries for recycling, and sell them around does not address the disposition of qualified companies. Can not guarantee that these companies harmless treatment, often leads to secondary pollution.

To industry sources, sales of enterprise products to enter the available directories, manufacturers must undertake to the point of sale of its lead-acid battery used lead-acid battery is responsible for providing replacement and recycling. Manufacturers must be the point of sale agreement, if the electric bicycle

In addition, manufacturers in the government sector for registration, must submit a corporate commitment and undertaking to properly handle the waste batteries. This includes ensuring that the recovery rate of waste lead-acid batteries in 2006 no less than 50% in 2007 no less than 70% in 2008 after no less than 85%.
