Sodium-ion Batteries

Sodium-ion batteries are a type of rechargeable battery that utilizes sodium ions (Na+) as the charge carriers. They function similarly to lithium-ion batteries, where the energy is stored and released through the movement of ions between the anode and cathode materials during charging and discharging cycles. Sodium-ion batteries are considered a promising alternative to lithium-ion batteries due to the abundance and cost-effectiveness of sodium compared to lithium. They are particularly appealing for large-scale energy storage applications, such as renewable energy systems, where resource availability and cost are critical factors. These batteries typically consist of a cathode made from sodium-containing compounds, an anode that can be composed of various materials, and an electrolyte that facilitates ion transfer. Researchers are actively exploring various materials and designs to improve the efficiency, energy density, and cycle life of sodium-ion batteries, making them a focal point in the development of sustainable energy storage solutions.
