Sodium Ion Battery

• AR4 Tech, a start-up in Coimbatore, has partnered Sodion Energy of Singapore to make sodium ion battery packs for domestic and export markets.

ABOUT SODIUM ION BATTERY

• Sodium-ion batteries (Na-ion batteries or NIBs) are an emerging battery technology that utilizes sodium ions (Na+) as charge carriers.
• Sodium-ion batteries offer an alternative energy storage solution to Lithium Ion Batteries (LIB) with potential benefits such as cost-effectiveness and abundance of sodium resources.
• Working (similar to LIBs)-
  • During charging, sodium ions are moved from the positive electrode (cathode) to the negative electrode (anode), and during discharge, they move back to the cathode, generating electrical energy in the process.

ADVANTAGES

• NIBs have a number of advantages over other types of batteries, including their safety, affordability, and long lifespan.
• They are a good fit for applications where fast charging and high discharge rates are required, such as electric vehicles which are required to climb slopes or carry heavy loads.
• NIBs also shine in applications such as Backup Power Supplies, Solar Energy Storage and even Starter Batteries for gasoline vehicles.
• NIBs are close to Lead Acid Battery LABs in price but perform similarly to LIBs.
