Batteries have revolutionized our lives, especially the invention of rechargeable batteries, which have enabled us to have cellphones, laptops, and electric vehicles. But as we transition to more forms of green energy, we're facing a serious dilemma: Will our current lithium-ion batteries be able to sustain us? Battery scientist Shirley Meng says we need to explore different metals and elements that could last longer and charge faster. Meng is a chief scientist at the Argonne National Laboratory and a professor at the Pritzker School of Molecular Engineering at the University of Chicago. For the past two decades, she has been pioneering research on new energy storage materials — ones that are affordable, can be mined ethically, and most importantly, ones that can be recycled efficiently.
