AR4 Tech, a start-up in Coimbatore, has partnered Sodion Energy of Singapore to make sodium ion battery packs for domestic and export markets.
Key Highlights:
Sodium-Ion Batteries (NIBs) were originally developed in the early 1980s, but large-scale development of the technology was abandoned in favor of Lithium-Ion Batteries (LIBs).
Nowadays NIBs are considered to be one of the most appealing alternative rechargeable batteries to LIBs.
Sodium-ion batteries generate electricity through a chemical reaction and are made up of an anode, cathode, separator and an electrolyte.
In a sodium-ion battery, lithium ions are replaced with sodium ions in the battery’s cathode, and lithium salts swapped for sodium salts in the electrolyte.
Operating Principle: During charging, sodium ions move from the cathode to the anode while electrons travel through the external circuit. During discharge, the reverse process occurs.
