Researchers over at the University of California, Riverside’s Bourns College of Engineering have come up with a lithium ion battery which is capable of outperforming the existing industry standard by three times, with the main material being sand. Sometimes, the best ideas come about unknowingly. Apparently, a member of the research team, Favors, was chilling out on a beach when he took a closer look at the sand and realized its main make-up was quartz, otherwise known as silicon dioxide.
Using sand, he milled it down to the nanometer scale, before purifying it to change the color to white from brown, before grounding salt and magnesium into the purified quartz. Heating this powder resulted in pure silicon, and the nano-silicon formed in an extremely porous 3-D silicon sponge like consistency which eventually proved to be a major factor in improving battery performance.
Will this lead to better lithium ion batteries down the road? Perhaps, and electric cars might just find themselves being on the rise compared to gas-powered ones in due time. [Press Release]
