Hindalco Industries shares rose after the Aditya Birla Group company announced a ₹21,000 crore expansion of its aluminium smelter operations in Odisha. However the stock ended lower.
The deets: the aluminium plant in Sambalpur that will add 3.6 lakh tonnes of annual capacity.
It has also started a new aluminium sheets and battery-grade foil unit with a capacity of 1.7 lakh tonnes, built at a cost of ₹4,500 crore.
The significance: the battery-grade aluminium foil plant, India’s first will supply enough material to support up to 100 GWh of battery production, using aluminium sourced directly from the company’s own facility.
100 GWh of lithium-ion batteries is enough to power about 1 million electric cars with a 100 kWh battery each (roughly the size used in big EVs like Tesla Model S or high-end electric SUVs).
In simple terms, these projects help India make key materials for lithium-ion batteries at home instead of importing them, supporting electric vehicles and energy storage.
The larger goal: the move is part of Hindalco's bigger plan to grow its aluminium business, with around ₹37,000 crore invested in Odisha and a total of ₹55,000 crore across India.
