Why India needs a circular battery economy, not just a recycling target 

When a battery dies in India, where does its lithium go? 

It is a simpler question than it sounds, and few in the industry can answer it with confidence. The battery may be collected, or it may not. It may be processed here, shipped abroad as black mass, or broken open in an unregulated backyard unit. The lithium, graphite and other minerals inside it, almost all of them imported in the first place, may return to an Indian factory. Or they may never be seen again. 

This is no longer an academic question. From 2027-28, India’s battery waste rules will require new batteries to contain domestically recycled material, rising to 20% by 2030-31. That turns recycled lithium from an environmental aspiration into a manufacturing input, one that must be available inside India, in volume and at battery grade, within a few years. 

The country is not yet set up to supply it. With limited domestic refining and no restriction on exporting black mass, much of the value in what India collects can leave before it is ever turned back into battery material. And with 8.2 GWh of storage added in the first half of 2026 alone, the volumes at stake are about to grow very quickly. 

More than an energy transition 

India’s energy transition is usually described as a move away from coal. At an industrial level, it is just as much a move towards materials. So far, the conversation about those materials has centred on import dependence, overseas mining deals and price volatility. But they treat a design problem as a supply problem and so miss half the picture. 

Making cells at home reduces dependence on imported batteries. On its own, it does not reduce dependence on imported materials. A genuinely self-reliant battery ecosystem has to account for the materials that come back, not only the cells that go out. 

The country is not starting from scratch. India’s organised lead-acid industry already runs one of the most effective materials loops in Indian manufacturing. Secondary lead now supplies more than 80% of India’s domestic lead output, and every gain in recovery shows up directly in material costs. For this industry, circularity is not an aspiration. It is already part of how it competes. 

For lithium-ion, the policy architecture is largely in place. The Battery Waste Management Rules, 2022 assign extended producer responsibility (EPR) to manufacturers and importers, set material recovery targets and phase in the recycled-content requirements. A ₹1,500 crore incentive scheme under the National Critical Mineral Mission rewards the actual extraction of critical minerals rather than black mass production alone. 

The foundations exist. What is missing is a system that turns them into retained value. 

Where the value leaks out 

The gaps begin with chemistry. Lithium-ion recycling economics were built around nickel and cobalt. Lithium iron phosphate (LFP), now the workhorse of stationary storage for its safety and cost, contains little of value apart from lithium. That does not make it the wrong choice for the grid. It means the recovery processes India builds must be designed around the chemistries it actually deploys, not those that made recycling profitable elsewhere. 

Timing compounds the problem. Near-term feedstock is thin and scattered across manufacturing scrap, consumer electronics and early electric two- and three-wheelers, yet announced lithium-ion recycling capacity already exceeds the volume of batteries reaching end of life. 

Even when batteries are collected, value can still escape. It lies not in shredding batteries into black mass but in refining that into battery-grade lithium salts and cathode materials, and India’s capacity to do so remains limited. 

Then there is trust. Organised recyclers carry the cost of pollution control and compliance; informal operators do not and can often outbid them for scrap. Concerns persist that EPR certificates are underpriced and that some recycling exists more on paper than in practice. Even in lead-acid batteries, where recycling systems are well established, an estimated over 50% of used batteries still pass through informal operators. The materials make their way back into circulation, but often at the expense of worker safety, environmental standards, and lost value for the formal ecosystem. 

Underlying all of this is a measurement problem. Most indicators still count volume: tonnes collected, capacity installed, certificates issued. They say little about whether India is keeping the value its batteries contain. 

From tonnes recycled to value retained 

The question India should be asking is not how much it recycles, but how much industrial value it keeps. 

That starts with measuring what matters. Alongside collection and capacity targets, India should track how much recovered material meets battery-grade specifications, how much re-enters domestic cell and materials production, whether recycled content can be traced from collection to a new battery, and whether recyclers earn their returns from materials rather than certificates. 

Those measures only work if the material itself can be trusted. For a cell maker, recycled material is useful only if it can be qualified exactly like virgin input, against the same specifications and the same tests. Without agreed standards, recycled-content mandates risk being met on paper rather than in product. 

Technology and collection need to follow India’s feedstock. That means processes that make LFP recovery viable, domestic refining that takes material all the way to battery grade, and collection that reaches where batteries actually are: rooftop and off-grid solar systems, inverters, telecom sites and small commercial fleets. Bringing informal collection networks into the formal system will work better than trying to shut them out. 

Finally, manufacturers and recyclers need to operate as one value chain, running from cell to grid and back to cell. Long-term offtake agreements, shared chemistry data and batteries designed for easier dismantling turn recovered material into a planned input rather than an afterthought. Business models can do the same work. When a manufacturer keeps ownership of a battery and offers storage or backup as a service, the battery comes back by design, and so does its material. 

The mine India already owns 

Lead-acid did not become one of the world’s most successful circular economies because a regulator ordered it to. It got there because recovered lead was worth more than it cost to recover, and because manufacturers controlled the dealer networks through which old batteries came back. Regulation helped formalise the loop. Economics closed it. 

That is the real lesson for lithium-ion. Mandates and incentives can start a recycling industry, but they cannot sustain one. The loop will close only when manufacturers have a commercial reason to want their material back: because it qualifies as cell-grade input, because it is cheaper or more secure than imports, or because they still own the battery when it retires. 

India is rightly measuring its battery ambitions by the capacity it builds. But for a country that still imports almost all of its lithium, capacity cannot be the final measure of success. Every gigawatt-hour installed today holds lithium India has already paid to import once. The question that will define its battery future is how well it can recover that lithium and return it to the cells it makes next. Is India building an industry that consumes its batteries, or one that inherits them?
