Tata Group’s battery manufacturing arm, Agratas Energy Storage Solutions, is developing its own lithium-ion cell technology for the first time, marking a strategic shift toward technological self-reliance as China tightens restrictions on battery technology transfers. Instead of relying on licensing agreements with Chinese companies, Agratas is building an in-house lithium iron phosphate (LFP) cell platform at its upcoming battery manufacturing facility in Sanand, Gujarat, according to people familiar with the matter.
The move reflects a broader transformation in India’s electric vehicle (EV) supply chain strategy, where companies are increasingly investing in indigenous battery technologies to reduce dependence on foreign intellectual property. Agratas, the Tata Group’s global battery business, had reportedly explored licensing battery technology from Chinese manufacturers but concluded that stricter export controls and geopolitical tensions made such partnerships increasingly unlikely.
Agratas Shifts to In-House Battery Technology
Agratas is constructing a pilot production line for LFP battery cells at its Sanand facility before scaling up commercial production.
The project represents:
- The company’s first internally developed battery cell technology.
- A shift away from reliance on Chinese technology licensing.
- An effort to build proprietary expertise in advanced battery manufacturing.
- A key step toward strengthening India’s domestic EV battery ecosystem.
Project Snapshot
| Item | Details |
|---|---|
| Company | Agratas Energy Storage Solutions (Tata Group) |
| Location | Sanand, Gujarat |
| Technology | Lithium Iron Phosphate (LFP) battery cells |
| Strategy | In-house battery cell technology |
| Objective | Reduce dependence on foreign technology |
Why Tata Is Developing Its Own Technology
The decision comes after China tightened export controls on technologies related to advanced battery manufacturing.
According to the report:
- Agratas assessed that securing a technology licensing agreement with a Chinese company had become highly unlikely.
- Building proprietary technology provides greater long-term control over manufacturing.
- The approach reduces geopolitical and supply-chain risks.
- It also gives the company flexibility to customize battery chemistry for future products.
The shift aligns with India’s broader push to localize critical technologies under initiatives aimed at strengthening domestic manufacturing and reducing dependence on imports.
Focus on Lithium Iron Phosphate (LFP) Cells
Agratas’ pilot line will manufacture LFP battery cells, which have become increasingly popular in electric vehicles and stationary energy storage.
LFP batteries are widely used because they offer:
- Lower production costs.
- Improved thermal stability.
- Longer operating life.
- Better safety compared with some nickel-based chemistries.
- Suitability for mass-market electric vehicles.
Although LFP batteries generally have lower energy density than nickel-rich alternatives, they are increasingly favored for affordable EVs and battery energy storage systems.
Why LFP Batteries Are Popular
| Advantage | Benefit |
|---|---|
| Lower Cost | More affordable battery production |
| High Safety | Better thermal stability |
| Long Cycle Life | Longer battery lifespan |
| Proven Technology | Widely adopted for EVs and energy storage |
Strengthening India’s Battery Supply Chain
The push for domestic technology extends beyond batteries at Tata, with Tata Electronics set to begin India’s first chip fab using 90nm process technology.
Agratas plays a central role in the Tata Group’s electric mobility strategy.
The company is developing large-scale battery manufacturing capacity to supply:
- Tata Motors’ electric vehicles.
- Energy storage systems.
- International automotive customers.
- Future clean energy applications.
The Sanand facility is expected to become one of India’s major battery manufacturing hubs as domestic demand for EV batteries continues to grow.
Why the Move Matters
The investment comes as the wider conglomerate reports strong results, with Tata Group’s profit jumping 52% to ₹1.7 lakh crore in FY26.
Developing proprietary battery technology offers several strategic advantages:
- Reduced dependence on overseas intellectual property.
- Greater resilience against geopolitical disruptions.
- Improved control over future battery innovation.
- Potential export opportunities for Indian-made battery technology.
- Stronger integration across Tata Group’s EV ecosystem.
The decision also reflects a broader trend of global automakers and battery manufacturers seeking greater control over critical technologies amid rising competition in the EV sector.
Looking Ahead
Agratas’ decision to develop its own lithium-ion cell technology marks an important milestone for both the Tata Group and India’s emerging battery manufacturing industry. By pivoting away from reliance on Chinese technology licensing and investing in proprietary LFP cell development, the company aims to build a more resilient and self-sufficient battery ecosystem capable of supporting the country’s rapidly growing electric vehicle market.
Looking ahead, the success of the pilot production line at Sanand will be critical in determining Agratas’ ability to scale commercial cell manufacturing and compete with established global battery makers. If the in-house technology proves successful, it could strengthen India’s ambitions to become a significant player in advanced battery production while supporting the localization of the EV supply chain and reducing dependence on imported battery technologies.
Frequently Asked Questions
What is Agratas building?
Agratas Energy Storage Solutions, Tata Group’s battery manufacturing arm, is developing its own in-house lithium iron phosphate (LFP) cell technology at a pilot line in Sanand, Gujarat, ahead of scaling up commercial production.
Why is Agratas moving away from Chinese licensing deals?
China has tightened export controls on advanced battery manufacturing technology, making licensing agreements with Chinese companies increasingly unlikely, so Agratas is building proprietary technology to reduce geopolitical and supply-chain risk.
Why did Agratas choose LFP battery technology?
LFP cells offer lower production costs, better thermal stability, longer cycle life and improved safety compared with some nickel-based chemistries, making them well suited for mass-market EVs, even though they have somewhat lower energy density.
