Tata's battery arm Agratas gives up on a Chinese technology licence and will build lithium cells on its own process at Sanand, as Beijing's export curbs harden
5 Aug, 04:36 IST · Plays out over months · 1 source
China has effectively stopped selling battery-making know-how to Indian firms, so Tata is now developing its own — which is slower and dearer, keeps electric vehicles costly for longer, and puts Indian battery makers who license Chinese technology, like Exide, in an awkward spot.
Key facts
What the reporting establishes, before any reading of it.
- Agratas Energy Storage Solutions is building a pilot line for lithium iron phosphate (LFP) cells at its Sanand, Gujarat gigafactory using its own process technology for the first time
- Executives concluded the chance of a technology deal with a Chinese firm is close to nil given Beijing's export restrictions on cell technology, equipment and engineers
- Its nickel-manganese-cobalt (NMC) line by contrast licenses mature technology from Japan's Automotive Energy Supply Corp, a unit of Envision Energy — showing non-Chinese licences remain available
- A mixed Indian, South Korean and Chinese engineering team will validate the first LFP batch before commercial production begins
- Peer read-across: Exide Energy Solutions licenses LFP technology from China's SVOLT; Amara Raja licenses Gotion technology through GIB EnergyX Slovakia, an EU-domiciled entity, and has pushed cell production out to FY2027
How the news spreads
Step by step — from the first companies it hits to whole sectors.
Who it hits first
- Agratas will build lithium iron phosphate cells at Sanand using process technology it develops itself, because it concluded no Chinese firm will license it under Beijing's export restrictions. Developing a cell process from scratch means low yields for longer and a higher cost per kilowatt-hour than a licensed line would deliver.
- Exide Energy Solutions is the most directly exposed listed company, because its lithium cell plan runs on a licence from China's SVOLT — the exact channel being closed.
- Amara Raja licenses Gotion technology through an EU-domiciled entity, GIB EnergyX Slovakia, which is a partial shield, but it has already delayed cell production to FY2027.
Who may gain
- Japanese, Korean and European technology licensors, whose licences remain available — Agratas' nickel-manganese-cobalt line already runs on technology from Japan's Automotive Energy Supply Corp, proving the non-Chinese route works.
- Battery makers with no Chinese dependency at all, such as HBL Engineering, whose railway, defence and industrial chemistries are its own.
- Indian engineering and research-and-development service firms, who get paid to help develop the process knowledge that is no longer available off the shelf.
Along the supply chain
Downstream
Downstream are the electric vehicle makers and grid-storage developers who were promised cheap domestic cells. Tata Motors Passenger Vehicles is Agratas' anchor customer and keeps importing cells for longer. Ather Energy and Ola Electric, who buy cells rather than make them, face the same extended import dependence. Grid-scale storage developers such as Tata Power bid fixed tariffs years before buying batteries, so a delayed domestic cell industry lands directly on their project margins.
Upstream
Upstream of an Indian cell plant sit three things China has restricted: the process licence, the manufacturing equipment, and the engineers who commission it. Agratas is working around all three by assembling a mixed Indian, South Korean and Chinese engineering team and developing its own recipe. Further upstream sit the cathode and anode materials — lithium iron phosphate powder, graphite anode, electrolyte and separator — which remain overwhelmingly Chinese-supplied and are the next obvious pressure point.
Where demand moves
Business
Demand for cell technology has been forced to re-route. It cannot flow to China, so it flows either to Japanese, Korean and European licensors, or to in-house development teams. The same re-routing hits equipment: electrode coaters, calendering machines and dry-room systems now have to be sourced outside China, which lengthens delivery times and raises capital cost per gigawatt-hour. Downstream, electric-vehicle makers keep importing finished cells for longer than planned, so demand that was supposed to become domestic stays offshore for another two to three years.
Capital
Capital is separating the cell-makers from the cell-buyers. Money should favour companies with non-Chinese technology paths or no cell dependency at all — HBL Engineering, and the engineering-services firms Codex flagged — and shy away from those whose entire investment case rests on a Chinese licence, principally Exide. On 4 August the market had not yet made this distinction: Exide rose 3.07% and Ather jumped 13.96%, both on company-specific results news rather than on this structural story, which is precisely why it is not yet in the price.
How it spreads across sectors
Automobile and Auto Components
The electric-vehicle cost curve stays higher for longer and import dependence persists, weighing most on companies whose investment case assumes cheap domestic cells.
Capital Goods
Battery equipment, dry-room and electrode-machinery orders shift from Chinese to Korean, Japanese and European suppliers, raising capital cost per gigawatt-hour.
Power
Grid-scale battery storage tenders carry more cell supply and price risk, squeezing developers who bid fixed tariffs years in advance.

When it plays out
Immediate
Little immediate price action — this is a strategy disclosure, not an earnings event. Watch for any statement from Exide or Amara Raja clarifying whether their Chinese licences are affected, which is the question that matters most.
Medium term
Over one to six months the real test is Agratas' pilot line yields at Sanand. If a self-developed lithium iron phosphate process reaches commercial yields, it becomes a template other Indian firms can follow and the whole sector re-rates. If it does not, India's cell localisation slips several years, electric-vehicle price parity is pushed out, and the cathode and electrolyte materials chain — still overwhelmingly Chinese — becomes the next chokepoint.
Short term
Over one to four weeks, expect analyst questions on licence security at both Exide and Amara Raja, and possible commentary on equipment delivery schedules. Any confirmation that a Chinese licensor cannot ship equipment or engineers would be the trigger that turns this from a background risk into a priced one.
