SRF Limited Approves INR 6 Billion Battery-Grade Aluminum Foil Plant in India
On October 21, SRF Limited’s board approved an investment of approximately INR 6 billion to establish a battery-grade aluminum foil manufacturing facility in India. The planned plant will have an annual production capacity of approximately 12,000 metric tonnes and is intended to serve both lithium-ion and sodium-ion battery applications. The investment represents a manufacturing expansion focused on a material used in two major battery technologies. The company plans to implement the project in two phases, with an estimated investment of INR 3 billion allocated to each phase. The announced schedule sets September 2028 as the expected completion date for Phase I and September 2030 for Phase II.
Investment and Planned Manufacturing Capacity
The approved investment of approximately INR 6 billion will fund the establishment of SRF Limited’s battery-grade aluminum foil manufacturing facility. According to the announcement, the plant is designed for an annual capacity of about 12,000 metric tonnes. This capacity provides the central production target for the proposed project, although the announcement does not specify separate output allocations for lithium-ion and sodium-ion battery applications. The investment and capacity figures describe the planned facility; they do not establish that production has begun or that the full annual capacity will be immediately available when construction is completed. Further details about the manufacturing process, site, equipment, or commissioning schedule were not provided in the shared announcement.
Two-Phase Project Schedule Through 2030
SRF Limited intends to execute the manufacturing project in two phases, each with an estimated investment of INR 3 billion. Phase I is expected to be completed by September 2028, while Phase II is scheduled for expected completion by September 2030. The phased approach divides the approximately INR 6 billion investment into two planned stages and establishes separate target dates for their completion. The announcement does not specify the production capacity assigned to either phase, whether output will begin before the completion of each phase, or whether the dates represent construction completion, commissioning, or commercial production milestones. These details remain unconfirmed in the information provided.
Battery Applications: Lithium-Ion and Sodium-Ion Technologies
The proposed facility is intended to supply battery-grade aluminum foil for both lithium-ion and sodium-ion battery applications. Including both technologies establishes the planned scope of the facility without specifying how much material will be allocated to either battery category. The announcement also does not identify individual customers, supply agreements, target markets, or end-use products. Accordingly, the confirmed development is the planned manufacturing capacity and its intended application across the two battery technologies, rather than a disclosed customer pipeline or a guaranteed level of demand. Additional information would be needed to establish how SRF Limited plans to position the facility within battery-material supply chains.

What Remains Unspecified
The announcement establishes the investment amount, planned annual capacity, intended battery applications, and expected completion dates for both project phases. However, it does not disclose the facility’s exact location within India, the identities of prospective customers, production ramp-up plans, or any confirmed supply contracts. It also does not specify whether the two phases will contribute equal production capacity, despite each having an estimated investment of INR 3 billion. These distinctions matter when assessing the project’s eventual supply contribution and commercial reach. Until further details are announced, the 12,000-metric-tonne figure should be treated as the planned annual capacity of the facility, not verified current production.
Industry Impact & Outlook
SRF Limited’s planned investment adds a proposed battery-grade aluminum foil manufacturing project to India’s industrial base for materials used in lithium-ion and sodium-ion batteries. If implemented according to the announced schedule, the facility could provide additional domestic manufacturing capacity for a material serving both technologies, while its planned 12,000-metric-tonne annual output offers a clear measure of the project’s intended scale. The two-phase timetable also means that the full project is expected to extend through September 2030. For battery manufacturers and other potential customers, the practical significance will depend on commissioning, usable production capacity, product qualification, and commercial supply arrangements, none of which were detailed in the announcement.
Frequently Asked Questions
1. What investment has SRF Limited approved for the battery-grade aluminum foil facility?
SRF Limited’s board approved an investment of approximately INR 6 billion on October 21 to establish a battery-grade aluminum foil manufacturing facility in India. The project is intended to serve lithium-ion and sodium-ion battery applications. The planned investment is divided into two phases, with an estimated INR 3 billion allocated to each phase. The announcement establishes the investment approval and intended manufacturing scope but does not provide details about the facility’s exact location, prospective customers, or commercial supply agreements.
2. What is the planned annual production capacity of the new facility?
The planned battery-grade aluminum foil manufacturing facility is expected to have an annual production capacity of approximately 12,000 metric tonnes. This figure represents the announced capacity target for the project, rather than confirmation of current production. The shared announcement does not indicate how much capacity will be installed during Phase I compared with Phase II. It also does not provide a production ramp-up schedule or a date when commercial output is expected to begin. Those details would be needed to assess when the planned capacity could become available.
3. Which battery technologies will the facility support?
The facility is planned to manufacture battery-grade aluminum foil for both lithium-ion and sodium-ion battery applications. The announcement identifies these two technologies as the intended application areas but does not specify the amount of production that will be allocated to either one. It also does not identify customers, supply contracts, or individual battery products that will use the material. Therefore, the confirmed scope is the facility’s intended ability to serve both battery categories, rather than a disclosed commitment to supply particular manufacturers or markets.
4. When are the two phases of the project expected to be completed?
SRF Limited expects Phase I of the battery-grade aluminum foil manufacturing project to be completed by September 2028, followed by Phase II by September 2030. Each phase has an estimated investment of INR 3 billion, together accounting for the approximately INR 6 billion project. The announcement does not clarify whether these dates refer specifically to construction completion, commissioning, or the start of commercial production. It also does not disclose the production capacity assigned to each phase, so the expected schedule should be distinguished from confirmed operational milestones.
5. How much investment is allocated to each project phase?
The project is planned in two phases, with an estimated investment of INR 3 billion for Phase I and another INR 3 billion for Phase II. Together, these allocations equal the approximately INR 6 billion investment approved by SRF Limited’s board. The announcement does not provide a more detailed breakdown of spending across construction, machinery, technology, or other project requirements. Nor does it specify whether the investment estimates may change as implementation progresses. The disclosed figures therefore describe the planned phase-wise allocation, not a final audited account of project expenditure.
6. What further information is needed to assess the project’s commercial impact?
Assessing the project’s eventual commercial impact will require additional information about its location, commissioning progress, production ramp-up, customer agreements, and allocation of capacity between the two battery technologies. The announcement confirms the planned annual capacity of about 12,000 metric tonnes and the expected completion dates for both phases, but it does not disclose these operational or commercial details. Information about product qualification and confirmed supply arrangements would also help clarify when the facility could contribute material to battery supply chains. Until such details are available, the announced figures remain project targets.
