Ah, rice: food staple enjoyed by billions of people around the world every day. And according to a recent report, it could soon be used to help power your cell phone.
Not the edible part of the rice, mind you: about 20 per cent of the total weight of all rice is its inedible husk, Wired reports. Researchers have found a way to recycle those husks and use them to make silicon for batteries.
In a study published with the Proceedings of the National Academy of Sciences of the United States of America, researchers say they believe there is a way to convert the silica layers found in rice husks and convert it to silicon, which can then be used in high-capacity lithium battery anodes. The researchers say that the structure of the rice husks gives it “excellent electrochemical performance as a lithium battery anode,” the study’s abstract states. By applying heat and acid to the husks, the silica can be extracted, and then converted into silicon.
Up until now, the waste husks have largely beenRead More »from How rice could one day power your smartphone
