Could future smartphone batteries be made even better using plain old beach sand? PhoneArena points us to a new study published at Nature.com that shows using beach sand as the primary ingredient for a smartphone battery’s anode could yield considerable improvements in terms of power efficiency. The anode is the component of the battery that serves as a terminal where positive electrical currents flow inside the battery from outside sources. PhoneArena points out that while smartphone battery anodes are typically made of graphite, it seems that researchers at the University of California and the Bourns College of Engineering have found that milling beach sand, purifying it and adding salt and magnesium to the mix while heating it was enough to make it into pure silicon
