For decades, scientists have sought ways to counter our dependence on lithium-ion batteries. These traditional, rechargeable batteries energize today's most ubiquitous consumer electronics -- from laptops to cell phones to electric cars. But raw lithium is expensive and is often sourced through fragile geopolitical networks. This month, chemists have announced an exciting alternative that relies on an organic, high-energy cathode material to make sodium-ion batteries, advancing the likelihood that this technology will find commercialization with safe, cheaper, more sustainable components.
