TCPL Packaging Limited Launches Strategic Venture into Lithium-ion Battery Separator Film Manufacturing

TCPL Packaging Limited Launches Strategic Venture into Lithium-ion Battery Separator Film Manufacturing​

TCPL Packaging Limited is expanding its business scope, having approved entering the manufacturing of lithium-ion battery separator films through a proposed subsidiary company. This strategic move positions the group in the rapidly growing ecosystem of advanced chemistry cell (ACC) battery materials and aims to bolster the localization of India's lithium-ion battery supply chain.

The decision follows an assessment by the Board of Directors, who approved the venture after reviewing a detailed presentation regarding the new line of business. The company plans to execute this foray into battery materials using the wet manufacturing process for lithium-ion battery separators and is building its presence across the entire separator value chain in a phased manner.

Market Demand Driving Separation Film Need​

The demand for battery technology components is accelerating sharply, driven by growth across electric vehicles (EVs), energy storage systems, consumer electronics, and railways. The domestic battery market shows significant projected growth across key segments:


The market development is supported by domestic policy, including the ACC Battery PLI Scheme, which has set a target of 50 GWh for domestic manufacturing capacity. Of this target, 40 GWh of capacity has already been awarded, with an incentive outlay amounting to ₹ 18,100 crore. Furthermore, the Grid-Scale Battery Programme includes a proposed domestic manufacturing capacity of 10 GWh for grid-scale BESS applications.

Critical Role and TCPL’s Capabilities​

Separator film is defined as a critical component in battery technology, playing a vital role in performance, safety, and longevity. Although these films represent only approximately 4–6% of the total battery cell cost, they are essential to enable safe and efficient operation by preventing physical contact between the anode and cathode, thus averting short circuits while enhancing overall performance.

TCPL Group is strategically positioned for this venture, leveraging its core competencies developed over years in the specialized film industry. These capabilities include advanced polymer handling, precision manufacturing at scale, strong process control and quality assurance, dedicated R&D and product development expertise, and specialized film processing.

The company views the project as a high-growth opportunity that enables participation in the localization of India's lithium-ion battery supply chain. It aims to establish a scalable manufacturing platform by combining its internal capabilities with necessary technical inputs.

Project Roadmap and Vision​

TCPL Packaging Limited has outlined a phased approach for execution. The proposed project configuration involves an investment of 125 Cr. The company targets commercialization of the lithium-ion battery cell production by 2027.

Looking ahead, TCPL projects a long-term vision to achieve 500 Mn sq. m. capacity, equivalent to approximately 50 GWh, over the next five to seven years. This platform is intended not only as a new business line but also as a significant avenue for long-term growth alongside the company’s existing operations.
