Tata Battery Unit Shifts to Indigenous Lithium Cell Technology

In August 2026, Agratas Energy Storage Solutions Pvt. Ltd., the Tata Group’s battery manufacturing arm, prepared to produce lithium-ion battery cells using its own proprietary technology, marking a significant step toward self-reliance in advanced battery manufacturing. The move comes due to the fact that China has tightened its export restrictions on critical battery manufacturing technologies, thus prompting the company to accelerate the development of indigenous capabilities for lithium iron phosphate (LFP) cell production.

Agratas has established a pilot production line for lithium iron phosphate (LFP) battery cells at its upcoming battery manufacturing facility in Sanand, Gujarat. The pilot line will serve as a testing and validation platform before the company begins commercial-scale manufacturing. By developing its own production technology, Agratas aims to strengthen its manufacturing expertise while reducing dependence on overseas technology providers.

To ensure high-quality production, Agratas has also assembled a multidisciplinary team comprising Indian, South Korean, and Chinese engineers. The team will optimize manufacturing processes, validate production parameters, and test the first batch of LFP battery cells produced at the pilot facility. Once the technology and production processes are successfully validated, the company will transition to full-scale commercial manufacturing.

Agratas’ decision represents a strategic shift in its battery manufacturing roadmap. Initially, the company explored the possibility of partnering with a Chinese technology provider. However, tighter export controls imposed by Beijing on critical battery manufacturing technologies significantly reduced the likelihood of securing such collaborations. Consequently, Agratas has chosen to develop in-house capabilities, enabling greater technological independence and long-term competitiveness.

Impact on the Chemical Market

This strategic move aligns with India’s broader objective of building a robust domestic battery manufacturing ecosystem to support the country’s rapidly growing electric vehicle (EV) and energy storage markets. By investing in proprietary lithium cell technology, Agratas is expected to strengthen indigenous battery manufacturing capabilities, reduce dependence on imported technologies, enhance supply chain resilience, support India’s clean energy and EV ambitions, and improve long-term manufacturing competitiveness.

As the demand for electric vehicles and energy storage solutions continues to grow, the ability to manufacture advanced lithium iron phosphate (LFP) battery cells using indigenous technology will become increasingly important. The company’s investment in homegrown battery technology positions the Tata Group to also play a key role in India’s transition toward sustainable mobility and clean energy while reinforcing the country’s ambition to become a global hub for advanced battery manufacturing.

Impact on the Lithium-ion Battery Market

The global lithium-ion battery market size is valued at USD 115.89 billion in 2025 and is predicted to increase from USD 137.33 billion in 2026 to approximately USD 555.15 billion by 2035, expanding at a CAGR of 16.96% from 2026 to 2035.

According to Precedence Research, the lithium-ion battery market is expanding rapidly due to surging global demand for electric vehicles, renewable energy storage, and high-performance consumer electronics. Advancements in energy density, fast-charging technology, and declining battery costs further accelerate adoption across automotive, industrial, and grid applications. The rising sustainability trend is also reshaping the market by driving demand for low-carbon materials, responsible mining practices, and recycling technologies that reduce environmental impact and strengthen supply security. Manufacturers all over the world are increasingly adopting greener production methods, closed-loop recycling systems, and next-generation chemistries to meet regulatory pressure and support global decarbonization goals.

The future of the lithium-ion battery market looks to be quite promising, as it is driven by the growing demand for environmental sustainability. The use of internal combustion engines (ICE) consumes carbon-based fossil fuels, emitting significant pollutants such as carbon dioxide into the environment. Several government organizations all over the world have released guidelines and launched initiatives in order to reduce the environmental burden of harmful pollutants. This also increases the demand for lithium-ion batteries, thus replacing ICE.

Impact on the Lithium Market

The global lithium market size is calculated at USD 11.05 billion in 2025 and is predicted to increase from USD 12.40 billion in 2026 to approximately USD 34.43 billion by 2035, expanding at a CAGR of 12.04% from 2026 to 2035.

According to Precedence Research, the surge in the global adoption of electric vehicles is a key driver for the lithium market.
