Scientists have found a way to make batteries cheaper using salt instead of rare metals. This could help lower the cost of phones, cars, and home power storage in the future. A team at the University of Houston created a new type of battery using sodium – the same basic mineral found in table salt. This battery can store 15% more power than similar ones made before. “Sodium is nearly 50 times cheaper than lithium and we can get it from seawater,” says lead researcher Pieremanuele Canepa. Why does this matter? Most of our phones and electric cars use lithium … Continue reading New Sodium Batteries Offer 15% More Energy, Cost 50x Less Than Lithium
