Sodium Ion Battery
AR4 a start-up in Coimbatore, has partnered Sodion Energy to make sodium-ion battery packs for domestic and export markets.
A sodium-ion battery (NIB) is a type of rechargeable battery that uses sodium ions (Na⁺) as the charge carriers, similar to how lithium-ion batteries use lithium ions.
Sodium-ion batteries are being explored as potential alternatives to lithium-ion batteries due to the abundance and lower cost of sodium compared to lithium.
They have the potential to address some of the challenges associated with lithium-ion battery technology.
Chemistry: Sodium-ion batteries operate on a similar principle to lithium-ion batteries.
During charging, sodium ions move from the positive electrode (cathode) to the negative electrode (anode), and during discharging, they move back from the anode to the cathode through an electrolyte.
Materials: The materials used in sodium-ion batteries differ from those in lithium-ion batteries.
For example, sodium-rich compounds are used in the cathode and anode materials to facilitate the reversible movement of sodium ions.
Abundance: Sodium is more abundant and widely available than lithium, which could potentially reduce concerns about resource scarcity
Lower Cost: Sodium-ion batteries have the potential to be cheaper to manufacture due to the lower cost of sodium-based materials.
Safety: Sodium-ion batteries might have improved thermal stability compared to lithium-ion batteries.
Energy Density: Sodium-ion batteries generally have lower energy density compared to lithium-ion batteries. This can affect the overall capacity and performance of the battery.
Cycle Life: The cycling stability and lifespan of sodium-ion batteries are still being improved, as they can degrade more quickly over multiple charge and discharge cycles.
Electrode Materials: Developing suitable electrode materials that can efficiently and reversibly intercalate sodium ions remains a challenge.
Sodium-ion batteries could find applications in various sectors, such as renewable energy storage, grid-level energy storage, and electric transportation.
However, their commercial viability and competitiveness depend on overcoming technical challenges.
Research and Development: Scientists and researchers are actively working to develop new electrode materials, electrolytes, and battery designs to enhance the performance and stability of sodium-ion batteries.
