- AR4 Tech, a start-up in Coimbatore, has partnered Sodion Energy of Singapore to make sodium ion battery packs for domestic and export markets.
- The sodium-ion batteries, developed by Sodion, will be made into battery packs here. AR4 Tech will use the packs to convert existing petroleum vehicles (mainly two-wheelers) into EVs.
- No quality or safety standards as yet in India for sodium ion battery packs – emerging sector – needs a ‘favourable regulatory environment.’
- Sodium-ion batteries (SIBs)
- Expected to be the most attractive economical and sustainable alternatives to lithium-ion batteries (LIBs)
- the abundant availability and reasonable cost of sodium
- Sodium-ion batteries in general have lower energy densities than LIB
- Sodium battery has wider temperature tolerance
- Easier to store and safer to transport
- Can be used for light electromobility and large-scale stationary applications
- More commercially viable for Indian markets
