Believe it or not, using sand as the key material, researchers have created a lithium ion battery that can outperform the current industry standard by three times. "This is the holy grail a low cost, non-toxic, environmentally friendly way to produce high performance lithium ion battery anodes," said Zachary Favors from University of California, Riverside in the US. Currently graphite is used in battery anodes, and further improvements on graphite are not viable.
