Developing High-Energy-Density Batteries Using Aluminum Foil

For the past three decades, lithium-ion (Li-ion) batteries have reigned supreme – proving their performance in smartphones, laptops, and electric vehicles. But battery researchers have begun to approach the limits of Li-ion. As next-generation long-range vehicles and electric aircraft start to arrive on the market, the search for safer, cheaper, and more powerful battery systems that can outperform Li-ion is ramping up.
