Sodium-ion batteries are an alternative battery technology that uses sodium as its primary raw material. They offer a number of advantages compared to lithium-ion batteries, especially in terms of cost, environmental friendliness, and safety. Sodium is much more abundant on Earth than lithium, making the sourcing of raw materials for sodium-ion batteries potentially more cost-effective and sustainable. Due to the greater availability and easier extraction of sodium, sodium-ion batteries are cheaper to manufacture than lithium-ion batteries, particularly when scaling up production. The extraction of sodium tends to have lower environmental impacts than the extraction of lithium, making sodium-ion batteries a more eco-friendly option.
