A Battery that Doesn't Need Lithium

Ben Miles looks at how lithium-ion and sodium-ion batteries are built differently, and how new advances in carbon-based materials are helping sodium become a realistic alternative to lithium batteries.

The analysis explains why lithium-ion batteries became the dominant technology, while also exploring how rising demand, higher costs, and supply chain concerns are creating opportunities for new battery types to compete.

Why it matters:
Battery technology powers everything from smartphones to electric vehicles and energy storage systems. Finding cheaper, safer, and more widely available materials like sodium could reduce dependence on limited lithium supplies, lower costs, and make clean energy technology more accessible worldwide.
