Battery made of sand


“Beach sand can be used to make lithium-ion batteries that last three times longer than current models.”

“This is the holy grail: a low-cost, non-toxic, environmentally friendly way to produce high performance lithium-ion battery anodes,” said Zachary Favors, a graduate student at UC Riverside, in a statement.

“With the new and improved performance of sand properties in a battery, it could mean expanding the expected lifespan of silicon-based electric vehicle batteries up to 3 times or more. For cell phones or tablets, it could mean having to recharge every three days, instead of every day.”
