Bhubaneswar: World’s largest aluminium rolling and recycling company, Hindalco Industries, has planned to expand its manufacturing capacity of fine-quality aluminium foil that is used in rechargeable batteries to serve the rapidly growing market for electric vehicles (EVs) and energy storage systems.
The company will invest Rs 800 crore to build a new plant near Sambalpur in Odisha that will initially produce 25,000 tonnes of the resilient product which forms the backbone of Lithium-ion and Sodium-ion cells.
According to industry sources, the demand for battery grade aluminium foil in India is expected to grow to 40,000 tonnes, primarily driven by mushrooming growth in gigafactories for advanced cell manufacturing.
“We are seeing a fast traction in battery materials demand, driven by an impressive outlook for the electric vehicle and grid storage sectors. Raw material localisation is critical in such strategic sectors,” said Satish Pai, managing director, Hindalco Industries.
“Hindalco is thus making various investments in battery materials and technologies towards building Atmanirbhar Bharat. Investment in this new battery foil mill is another such step in this direction,” said Pai.
Hindalco has claimed to have already achieved the technology breakthrough of manufacturing fine quality battery foils at its Mouda unit in Maharashtra. The Mouda unit is currently in the process of qualifying with Lithium-ion cell manufacturers in India, Europe and the United States. The new unit in Odisha will further augment capability to supply material to Gigafactories across the world.
High performance aluminium foils are used by cell makers as a current collector for the cathode materials. Hindalco’s deep understanding of metallurgy, extensive experience in sheet and foil rolling and access to its own aluminium metal gives it a formidable launch pad. The company is already developing such foils to raise the bar on mechanical strength, fine-tune the thickness and enhance surface characteristics of these advanced application foils. It is working on new coatings on the battery foils that will boost performance by delivering better adhesion, lower resistance, and reduced corrosion.
