A breakthrough in EV battery tech

Sodium-ion battery offers a potential low-cost alternative to lithium-ion battery for India and presents an opportunity to achieve energy independence

Lithium-ion batteries have been the go-to technology for vehicle electrification over the last decade. However, the rapid rise in the electric vehicle (EV) demand in the past two years has resulted in massive pressure on the battery supply chain. This makes it indispensable to diversify into newer battery technologies beyond lithium. Sodium-ion is a promising technology to complement lithium-ion batteries or even replace them in some cases.

India is taking successively bigger initiatives to develop energy sustainability and independence. The latest Economic Survey noted that with the aim of electrifying 30 per cent of India’s vehicle fleet by 2030, the
