Every layer of a battery cell — and every material inside it — is now being made in India. That is the claim Union Minister Ashwini Vaishnaw made on Friday, September 25, 2026, in a thread post on X spotlighting the country's advancing domestic battery manufacturing ecosystem. Posting as part of a numbered thread, Vaishnaw wrote: 'A battery cell needs several materials to work. Each layer, each material — is being made in India!' The post, accompanied by an image, is part of a broader communication effort to highlight the depth of India's push into the battery supply chain — not just finished cells, but the constituent materials that go into each one.

From cells to components: the supply chain logic

A modern battery cell is a layered structure — cathode, anode, separator, electrolyte, and casing — each requiring specialised materials and manufacturing processes. For years, India imported most of these inputs, leaving its nascent electric vehicle industry exposed to global supply-chain shocks and foreign pricing. The minister's emphasis on 'each layer, each material' signals a claim that this dependence is being systematically dismantled. This push is anchored in the Production Linked Incentive (PLI) scheme for Advanced Chemistry Cells (ACC), approved by the Government of India in 2021 with a budgetary outlay of Rs 18,100 crore. The scheme was designed to attract investment into domestic battery cell manufacturing — and, critically, into the upstream materials that feed those cells — with the goal of building an integrated, India-rooted EV supply chain.

Atmanirbhar Bharat's clean-tech front

The battery sector sits at the intersection of two of the government's most consequential policy bets: the shift to electric mobility and the Atmanirbhar Bharat drive in electronics and clean technology. Import dependence on battery materials — many of which are sourced from China — has long been flagged as a strategic vulnerability. Domestic production of those materials, if scaled, would insulate Indian EV makers from price volatility and geopolitical disruption. EV manufacturers and battery component suppliers are the direct stakeholders watching the ACC PLI scheme's implementation. The key question going forward is how quickly new domestic facilities for cathode active material, anode graphite, electrolyte salts, and separator film can reach commercial scale — and whether the PLI incentive structure is sufficient to sustain them through the capital-intensive early years. If India's battery material ecosystem is as broad as Vaishnaw's thread suggests, the next challenge is not just making these materials — it is making them competitively enough to power an EV industry that can win on price.
