Why doesn't India have indigenous lithium-ion battery cell gigafactories?

As of October 2025, India had commissioned 1.4 GWh of lithium-ion battery cell manufacturing capacity — 2.8% of the 50 GWh the country set out to build, and all of it from a single company. Its dependence on imported cells remains close to 100%.

A lithium-ion cell gigafactory is one of the harder pieces of industrial hardware a nation can attempt. At scale it is possessed by only four countries — China, South Korea, Japan and the United States — with China holding the majority of installed capacity. The difficulty is not the chemistry alone but the chain beneath it: refining raw lithium into battery-grade chemicals, producing cathode active material, and operating precision electrode-coating and cell-assembly lines to consistent tolerances across tens of gigawatt-hours. Each layer is a distinct capability. India today has none of the first two at commercial scale, and only an emerging position in the third.

The formal push began in October 2021, when the Advanced Chemistry Cell Production Linked Incentive scheme set a target of 50 GWh of cell capacity by 2025, backed by a ₹181 billion outlay. Four years on, the commissioned figure is 1.4 GWh, produced entirely by Ola Electric. Ola planned to commission 5 GWh of a 20 GWh line by March 2026, then scaled back, now aiming to install 5 GWh by FY2029. Reliance New Energy has indicated on-time commissioning of a 10 GWh second-round award and has positioned itself for roughly 30 GWh of annual capacity with investments of ₹7,500 crore, though no confirmed output has been reported. Tata's Agratas Energy Storage has announced a 20 GWh plant at Sanand, Gujarat, without a reported commissioning date.

The scoreboard is therefore early but not empty. Commitments across multiple players target more than 150 GWh operational by 2030, with committed investments exceeding ₹75,000 crore. Announced capacity is geographically concentrated: Tamil Nadu, Gujarat and Maharashtra together host about 72% of it, suggesting the outlines of regional manufacturing clusters.

Why the gap persists is structural, and the IEEFA/JMK assessment of January 2026 is specific about it. Beneficiaries under the scheme have run into three binding constraints. The domestic value addition rules are stringent, requiring builders to source a rising share of components locally at a time when the upstream — lithium refining and cathode material — does not yet exist in India. The installation timeline of two years is aggressive for a first-of-its-kind plant. And visa approvals have been delayed for the Chinese technical specialists needed to install equipment, since much of the world's cell-line hardware and know-how sits in one country.

These constraints interlock. A gigafactory cannot hit high domestic value addition without a domestic materials supply chain; that supply chain cannot mature without demand from operating gigafactories; and neither can start on a two-year clock while the specialist labour to commission the machines is held up at the border. The cell plant is the visible layer, but the missing capabilities beneath it — refining, cathode production, assembly equipment — are what actually gate the climb.

What it would take follows from the diagnosis rather than from ambition. Cell capacity at gigawatt-hour scale rises with the layers under it: battery-grade chemical processing, cathode active material, and domestically available assembly equipment and the expertise to run it. Timelines and value-addition rules that assume those layers already exist will keep slipping against them. The 150-plus GWh of commitments for 2030 is a genuine intent, and the first 1.4 GWh proves the manufacturing is not impossible in India. The distance between the two is a supply chain that has yet to be built.
