High performance batteries from rice residues
Each year, 20 million tons of rice husks . Researchers view it contains silicon enormous potential : Because of the tunnel and pore residues are excellent for batteries.

In the bowls of rice stuck to enormous forces - if you can unleash it

Rice husks contain important basic materials for high- tech products : Korean scientists gain from rice husk raw materials for high -performance batteries . The silicon contained in the shells lend itself particularly well for electrodes in lithium -ion batteries , the researchers write Jang Wook Choi of South Korea's Chungnam National University in the "Proceedings " of the U.S. National Academy of Sciences ( PNAS ) . Because of its tunnel and its tiny pores , it shows " excellent electrochemical behavior " .

100 million tons of rice farmers harvest every year worldwide , the husks make up about 20 percent of the weight off. Until now uses it mainly as a fertilizer additive or as a base for livestock. But the drop in the plant can also help to meet the increasing demand for silicon as an electrode material , the researchers write. Compared to the currently used graphite silicon could theoretically bind ten times the charge carriers and make the battery as powerful.

Protection and pulling at the same time

Porous materials are particularly suitable because they have a larger surface than smooth materials , and so can bind more carriers for electrodes. Although there are already artificially produced silicon material with tiny cavities , the researchers concede . However, the voids in silicon from husks are better connected to each other . This lead them to the fact that the rice husks protect the grain from insects and bacteria, but at the same time should not let air and moisture.

The researchers solved the silicon with an acid and heat from the silica, as it is in the husks . Here, the silicon gets a three-dimensional crystal structure , is maintained in the tunnel and pores. According to the researchers, this porous structure also prevents cracks in the electrode material and the loading capacity decreases . For the charging and discharging of the battery , the expansion of the silicon electrode is changed by up to 300 percent .

Silicon alloy                               

It may be the new super battery for electric cars E -Mobile have problems. They are expensive and have a short range. The inconvenience of batteries brakes yet the entire electro-mobility. A new type of battery is the solution. By Stefan WeissenbornPhoto: sekisuichemicalThe breakthrough ? This silicon alloy has the Japanese company Sekisui Chemical develops and thus optimizes the usual electric cars lithium - ion batteries. Equipped with the innovation could the reach of electricity to rise to around 600 kilometers - with plummeting costs of electricity storageRelated LinksE- mobile from Korea : Kia Soul EV - electric vehicle pure soulAudi A3 e-tron : Audi's last chance in the electricity marketFinding a parking space : This e- mobile kugelt like an armadilloNew World Record : electric racer storms to a stunning 328 km / htopicsbatteriesSo far, only short strides in technological development were observed. But is it that what the Japanese company Sekisui Chemical as widespread these days , voices, smite the hour of electric cars. As a practical vehicle with a long range - not only in the wishful thinking of the policy or the praises of car manufacturers on their products , which are often too quickly run out of juice .A new super battery believe the Japanese have developed the battery cars could help to reach around 600 kilometers expects the Blog Electric ago. This would correspond roughly tripling the previous maximum possible radius of action in electric cars because according to increasing battery capacity.To date, electric cars are often in practice no more than 100 kilometers. And when it gets cold in winter , the possible with a complete charge current routes halve quickly, because bone-chilling temperatures are the enemy of power storage .Up to 600 km range50 km - which managed just 30 years ago already the Golf I CityStromer , Volkswagen served as a testbed until 1986. With its lead-gel battery , the Wolfsburg came up to so far. This example shows how to slow the development of the cells for power storage takes place, how cumbersome is research.The breakthrough will Sekisui Chemical have managed with a new method which sets instead of the usual case of lithium -ion batteries, carbon materials for storage on a special silicon alloy and increases the conductivity. Also new are gel-like electrolytes, which should speed up the production process significantly . Hybrid VanToyota Prius is for the frugal family E -MobileThe i -road winds its way through the traffic electromobilityFrom Beetle to rattling whirring electric car alternative EnginesWith the Twizy across the countryAnother advantage could be the variable design. Thus, the Sekisui memory could easily be integrated into electric cars , which could resolve the problems of space by bulky power batteries. In addition, the new type of crash is safer than products on the market .But apparently the Japanese have even more in store : Because in addition to the technological quantum leap Announces Sekisui Chemical and vigorously to turn the screw costs , which would end consumers increasingly move to buy an electric car .Cost to be reduced by one-thirdThe company promises the cost per kilowatt hour by the new construction by almost two thirds to reduce ( 60 percent). Thus, a battery would cost for an average electric car is no longer around 15,000 euros , but 5000 euros . The result is that electricity could be offered at prices as cars with diesel or even gasoline engine.According to the website " Japan Market Online", which is operated by the German Chamber of Industry and Commerce in Japan ( GCCIJ ) , Sekisui Chemical is planning to ship as early as next year, the first test batteries of the new type of battery manufacturers. The news of the miracle battery caused the stock price of the company recently by 20 percent up fast , which enabled the stock market traders ever been in sparkling mood.If everything is correct , what is known about the Japanese battery innovation and also get the new developments in the electric cars whose drivers are likely to soon have something to celebrate . By 2015 to begin mass production , Sekisui Chemical said. His research has presented the company is currently on the eco - fair Eco Products 2013 in Tokyo.

                                                 battery prices decline
                             2008: 1200 US$/KWh  2018: 108 US$/KWh
The forecast for all companies involved in the market is a further decline of prices in a similar Dimension for the next 10 years. At least 90%,so that in 2028 a 1 KWh battery storage will cost only 10 US$.
    A 1/10 of the actual lithium battery 1 KWh power delivery price would become  down to 2 US cent cheap !
