RIVERSIDE, Calif., July 9 (UPI) -- Most lithium ion batteries rely on anodes -- positively charged electrodes -- made of graphite. But scientists have come to the conclusion they've pushed graphite to a point of maximum efficiency, and thus if longer lasting, less wasteful batteries are going to be made, a new material must be sourced.
Researchers at the University of California Riverside say that material should be, or at least could be, sand.
