What are Sodium-Ion Batteries?

Sodium-ion batteries are a type of rechargeable battery that uses sodium ions as the primary charge carrier. They are seen as a potential alternative to lithium-ion batteries because sodium is more abundant and less expensive than lithium.

1. How do Sodium-Ion Batteries compare to Lithium-Ion Batteries?

Sodium-ion batteries and lithium-ion batteries have several differences:

1. Material Cost: Sodium is more abundant than lithium, which makes sodium-ion batteries potentially cheaper to produce.
2. Energy Density: Lithium-ion batteries generally have higher energy density, meaning they can store more energy in a smaller space compared to sodium-ion batteries.
3. Performance at Low Temperatures: Sodium-ion batteries tend to perform better in low-temperature conditions than their lithium counterparts.
4. Cycling Stability: Many sodium-ion battery technologies have shown improvements in cycling stability, which refers to how many charge and discharge cycles the battery can endure over time.

2. Who are the Major Sodium‑Ion Battery Manufacturers?

Several companies have started investing in sodium-ion technology:
