[J72]5 Surprising Truths About Zapping the Future of Batteries with Lasers
5 Surprising Truths About Zapping the Future of Batteries with Lasers We all want it: the smartphone that lasts for days, the electric vehicle that drives a thousand miles on a single charge. But we’ve hit a wall. Today's lithium-ion batteries, which rely on graphite anodes, are nearing their theoretical energy density limit of around 250 Wh kg⁻¹ . To make the next great leap, we need a new material: Lithium Metal . Considered the "holy grail" for next-generation batteries, it boasts a massive theoretical capacity of 3860 mAh g⁻¹ , nearly ten times that of graphite. However, it comes with dangerous baggage: short-circuiting dendrites and extreme reactivity. To solve this, researchers are turning to lasers —a contactless processing method offering unprecedented precision. In the process of figuring out how to zap lithium into shape, they’ve uncovered some surprising truths. ...
