Scientists Can Create Smartphone Batteries Anodes With Recycled Rice Husks

Rice is a staple food for nearly half of the world’s population, but 20% of the grain’s annual production of  10⁸  tons is inedible and discarded for low-value uses such as kindling. Scientists are hoping to convert the husks’ silica into high-value silicon for smartphone batteries. An added benefit to using rice silica is its higher rate of efficiency compared with traditional silicon alloys.
