Sodium-based refers to compounds or materials that contain sodium, a chemical element with the symbol Na. Sodium is an essential mineral found in various forms, such as sodium chloride (table salt) and sodium bicarbonate (baking soda). These compounds are commonly used in food preservation, cooking, and various industrial applications. In the context of batteries, sodium-based technologies, like sodium-ion batteries, are being explored as alternatives to lithium-ion batteries. They offer potential benefits, such as lower costs and abundant raw materials, making them an attractive option for energy storage solutions in the future.
