Use rice husks to produce electric batteries

The grain of rice husk (rice husk) is considered to be worthless in industry, but millions of tons of waste products produced annually by the agricultural industry can be used to produce car batteries using a new research.

Lithium-ion batteries have so far existed two issues of low cost and safety. However, a new study shows that the price of this battery can be reduced by taking advantage of a surplus product in agriculture: rice husk.

Researchers at Chungnam University, Korea, have discovered a new application potential for rice husks, which accounts for about 20% of the harvested grain weight, equivalent to a total volume of more than 80 million tons. created every year. They found that silicon oxide inside rice husk can be converted into silicon for use in high-capacity lithium batteries. Silicon is the material most commonly used in the battery industry, especially when the market for hybrid and electric vehicles explodes, the demand for this material is much higher. New findings on the application of rice husk martial arts can make the price of electric batteries significantly reduced.

Rice husks, an agricultural waste product will be useful and protect the environment in a new role: producing lithium batteries.

The team has achieved many steps in separating silicon oxide. Through heat and acid treatments, they found that the silicon has an outstanding electrochemical function when it comes to using anodic battery, which finds great applicability. Large of husk martial arts.

Researchers recently said that the green technology in the automobile industry is not really 'green' as many people think because although the products are produced less emissions of air pollution, however the production process They leave many consequences for the environment. Toyota was recently criticized for its plan to build a technology center and test car, used for the study of green cars, 30km from their headquarters in Aichi. Under this plan, Toyota will have to clear an area of ​​more than 650 hectares, including about 270 hectares of forest and hills and 17th-century rice land.

With the discovery of new applications of rice husks, it is not surprising if Toyota participates in the study of this new application to 'neutralize' the criticism, and if it is produced by the new method, Lithium Battery -ion ​​will truly 'green' as expected of a new energy. Not only that, this technology will also make the way of agricultural policy makers to change the way they think about technology when they take advantage of the inherent strengths instead of following the automotive industry goals. dreamy, far away does not go anywhere.
