# Tata Technologies' China Unit Expands Collaboration with Agratas for Battery Development Shanghai operations provide ₹7.34 crore in services as Indian battery venture deepens Chinese supply chain ties. - **Source:** [mint - companies](https://www.livemint.com/rss/companies) - **Published:** 2026-09-24 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/aa10b3b2-8801-456c-8fb8-29b6a9c62051 ## China operations ramp up Tata Technologies' Shanghai unit provided ₹7.34 crore worth of engineering services to Agratas in FY26, marking its first disclosed collaboration with the battery venture. This contrasts with zero services in FY25, indicating a strategic shift toward Chinese technical expertise. The Shanghai entity specializes in manufacturing technology consulting and software services critical for lithium-ion battery development. Agratas is preparing for commercial rollout of its battery solutions. ## European engagement declines Concurrently, Agratas reduced its dealings with Tata Technologies' European engineering unit from ₹41.2 crore in FY25 to just ₹5.01 crore in FY26. This 88% reduction suggests a geographical rebalancing of technical partnerships. Total transactions across all Tata Technologies entities fell from ₹49 crore to ₹20.67 crore year-on-year, with Pune-based services accounting for ₹8.3 crore of FY26's total. ## Dual Chinese partnerships Agratas maintains two significant Chinese connections: through Tata Technologies' Shanghai operations and technology partner AESC, which holds a 12% stake. The venture purchased ₹4.43 crore worth of sample cells from AESC's Jiangsu subsidiary for its own battery development. These relationships provide access to China's advanced battery manufacturing ecosystem amid growing technology transfer restrictions. ## Strategic IP agreements Agratas secured intellectual property rights through its partnership with China's Envision Group-owned AESC, covering both NMC and LFP battery technologies. This comes as Beijing tightens controls on technology exports, forcing competitors like Amara Raja to revise plans. The collaboration helps Agratas navigate China's complex regulatory environment while accessing critical battery chemistries. ## Manufacturing scale-up Agratas is constructing a 40GWh battery plant in the UK and a 20GWh facility in India for EV and energy storage applications. It signed a ₹5,000 crore deal with Jaguar Land Rover for seven-year battery supply starting FY27. These developments position Agratas among India's most ambitious battery ventures, though dependent on Chinese technical expertise during scale-up. ## Industry dependency challenge HSBC analysts note India's battery sector remains 10 years away from self-sufficiency, despite 200GWh of announced capacity. Execution delays, financial viability concerns, and reliance on Chinese/Korean technology licensors create bottlenecks. Agratas' Chinese partnerships aim to bridge this gap during the critical transition from development to commercial production. ## Ecosystem access advantage Experts highlight that Chinese collaboration provides more than chemical formulations - it offers entry to the entire manufacturing ecosystem. This includes supply chain networks, production know-how, and equipment access that accelerates commercialization. For Agratas, proximity to China's battery value chain may prove decisive in achieving scale before domestic capabilities mature. ## Strategic positioning Agratas' dual approach - combining Tata's engineering resources with Chinese technical partnerships - creates a unique position in India's emerging battery sector. While dependent on foreign technology in the near term, these relationships could accelerate knowledge transfer and local capability building. The venture's success may influence how other Indian manufacturers navigate global battery supply chain dynamics. ## Sources covering this story - https://www.livemint.com/companies/news/tata-technologies-china-agratas-lithium-ion-battery-production-11790157502423.html — --- _Summary written by Brifing from the original reporting.
