                                                                                                      The environment-friendly rechargeable battery         With the wide use of all sorts of electronic gadgetry items the invention of battery seems to be the most useful innovations of the modern time. Apparently some types of traditional cells contain either mercury or cadmium and thus are a serious environment-hazard. While efficient, they contain the dangerous heavy metal cadmium or mercury that could in the future face restrictions - even a ban.          Facing with this severe situation, an environment-friendly rechargeable battery came into being, and the resultant battery should have the capable of meeting the triple demands of high cycle life, high specific energy and power, low cost, safety and durability. In order to meet customers’ requirements in terms of high cycle life, high specific energy and power, low cost and low pollution, some battery developers are working hard.          

         As a large carmaker country - Japan, Japan's auto battery industry has been developing in a high speed          There is a piece of latest news about the Japanese battery manufactures at 21 July 2008.          According to the Nikkei business daily rival Japanese automakers Toyota Motor and Nissan Motor Co will work with Matsushita Electric Industrial Co and other Japanese companies to set up common standards for lithium-ion batteries being developed to power next-generation cars.           Earlier in May Toyota, which leads the industry with its gas-electric hybrid Prius and Matsushita had announced a joint venture, Panasonic EV Energy Co, to set up two plants to make batteries for environment-friendly gas-electric hybrid vehicles.          Their venture aims to increase production of nickel-metal hydride batteries while aiming to start mass production of next-generation lithium-ion batteries. Apart from Toyota's alliance with Matsushita, other auto makers in alliance to develop lithium-ion batteries include Nissan with NEC Corp group and Mitsubishi Motors with G S Yuasa Corp.           Lithium-ion batteries, commonly used in laptop computers and mobile phones, are seen as a key component to improving the performance of pure electric vehicles and plug-in hybrid cars as they are said to produce more power and are smaller than nickel-metal hydride batteries, which are now used the Prius.           The report credits the initiative for setting up a common global standard for lithium-ion batteries to an affiliate organization of the Japanese ministry of economy, trade and industry that brings together nine automobiles firms, six battery makers and utility Tokyo Electric Power Co to draft the standards that include testing and charging methods, vehicle safety and other areas.            The group aims to push for its specifications to be adopted by the International Organization for Standardization as the global standard for lithium-ion batteries.             A common standard would help battery makers cut development costs and enable Japanese automakers gain an edge over their US and European rivals who are in a race to introduce zero emission hybrids as consumer preference steadily shifts to greener vehicles against a backdrop of rising fuel prices. 

                                                                                                                       Environment friendly Battery Vehicles          The new generations of power sources for your electronics – The Smart Nano battery – which can be dormant and harmless in non-use, provide energy when activated and then even render itself harmless when it has no more power to give.           It’s true the Nano battery still at its phase 1 of experiments - a prototype. According to a brief press release, the Nano batteries still in prototype are using various chemicals as electrolytes residing on top of Nano structures in a dormant state and when triggered, case an electrochemical reaction to produce a measurable voltage and current under a load. Apparently this chemical reaction then knows enough to reserve some cells that can create the neutralizing chemical reaction at the end of life, and just cut the way for the normal batteries catastrophic accidents.            The bottom line is, the Nano battery was designed to be environment friendly “Green”.
