Why Big Tech is Replacing Lithium Batteries

For more than 30 years, lithium-ion batteries have powered our phones, laptops, electric cars and increasingly our energy grids. But another battery technology that was largely left behind decades ago is making a comeback: sodium-ion. In 2026, CATL and CHANGAN unveiled a mass-production passenger vehicle powered by sodium-ion battery technology — bringing a chemistry once overshadowed by lithium much closer to everyday use. In this video, we follow the full story: • Why lithium-ion won the original battery race• Why sodium-ion was left behind• What changed to bring sodium back• How sodium-ion batteries actually work• Why hard carbon became so important• How CATL, HiNa Battery, JAC and others helped move the technology into real vehicles• Why sodium-ion performs surprisingly well in extreme cold• Where sodium could have advantages in EVs and grid storage• Why lithium-ion is still difficult to replace• And why the future of batteries may involve several chemistries rather than one winner Sodium-ion isn’t here because lithium failed. It’s here because the world now needs so many batteries that one chemistry may no longer be enough. This is Neuronary — where your scroll turns into skill.
