India must build an integrated battery value chain that connects cell manufacturing, second-life deployment and end-of-life recycling if it wants to underpin its electrification push, speakers at a conference convened by The Energy and Resources Institute (TERI) concluded.

The message from the TERI-organized event, reported by Energetica India Magazine, is structural rather than aspirational: the three segments of the battery economy are currently developing in isolation, and that fragmentation threatens both material security and the economics of India's storage and mobility build-out.

The integration argument

Delegates framed the challenge around material flows. Cells manufactured in India — whether under production-linked incentive schemes or through joint ventures — will eventually exit their first application, typically in electric vehicles or grid storage. What happens next determines whether lithium, nickel, cobalt and graphite re-enter domestic supply chains or leave the country as low-value scrap.

The conference position, as summarized by Energetica India, is that India needs all three links operating together: manufacturing capacity to create domestic demand for recycled feedstock, second-life applications to defer recycling and extract more service value from each pack, and recycling capacity to close the loop and reduce import dependence on critical minerals.

Second-life use received particular attention. Batteries retired from electric vehicles at 70–80 percent state of health can still serve stationary storage duties, delegates noted, extending the interval before recycling becomes necessary and improving the lifetime economics of each pack.

Why the sequencing matters

The argument for integration rests on scale timing. India's electric two-wheeler and passenger vehicle fleets are still young, which means a meaningful volume of retired packs will not arrive for several years. That window, speakers suggested, is when the country should establish collection systems, diagnostic standards for second-life grading, and recycling capacity — rather than waiting for end-of-life volumes to force improvisation.

A fragmented chain carries costs. Without domestic recycling, black mass and spent cells ship overseas and the recovered materials return as imported precursor chemicals. Without standardized second-life grading, repurposing stays a cottage industry unable to absorb pack volumes at scale. Without a manufacturing base, recyclers lack a guaranteed offtake for recovered materials.

What to watch

The TERI conference output is a policy signal, not a regulation. It lands in a policy environment where India has already moved on battery waste management rules requiring extended producer responsibility and setting recovery targets for recyclers, and where production-linked incentives continue to expand cell manufacturing capacity onshore.

The test now is whether those instruments get stitched together — whether, for example, EPR collections feed certified second-life grading and domestic recycling capacity on a timeline matched to manufacturing ramp-ups. That linkage, more than any single announcement, will decide whether India's battery chain closes or leaks.
