It’s no surprise that India needs a robust battery manufacturing infrastructure to accelerate its transition to clean mobility. The battery manufacturing segment remains a critical cog in the overall EV (electric vehicle) ecosystem development and is garnering a lot of attention. EV penetration across automotive segments is expected to grow exponentially over the next decade; with battery remaining the most critical and costly component of an EV. Given the incremental demand from various applications and future growth prospects (post 2030), ratings agency ICRA estimates investments in cell manufacturing to exceed $ 9 billion or Rs 70,000 crores.
“In EVs, advance chemistry batteries remain the most critical and the costliest component, accounting for almost 35-40% of the vehicle price. At present, battery cells are not manufactured in India, and thus most OEMs rely on imports, and manufacturing operations in India are limited to the assembly of battery packs,” Shamsher Dewan, Senior Vice President & Group Head - Corporate Ratings, ICRA, said. “However, to achieve mass scale penetration of EVs and a competitive cost structure, India will need to create its own eco-system of developing battery cells locally,” he adds.
In addition to the robust demand from EV vehicle, the annual battery demand for stationary applications (grid storage, telecom towers etc.) is also likely to grow at a rapid pace and be substantial, ICRA said. According to the agency, locating cell manufacturers close to the original equipment manufacturers (OEM) would allow for the creation of a research and innovation ecosystem, which would aid the development of batteries with improved energy efficiency and which are better suited to Indian climatic conditions.
The Government of India (GoI) recently signed agreements with three companies for incentives under its Production-Linked Incentive (PLI) Scheme for Advanced Chemistry Cell (ACC) Battery Storage. The policy emphasises on enhancing domestic value addition and is expected to support capability development in this sunrise. ICRA said that Lithium-ion batteries have emerged as the battery of choice for EVs, given their high energy efficiency, decent thermal stability and low self-discharge. While Lithium Nickel Manganese Oxide (NMC) is the most prevalent cathode chemistry currently, Lithium Iron Phosphate (LFP) chemistry is expected to gain increased acceptance going forward, given its higher thermal stability and lower production cost. “Multiple other chemistries also continue to be under development, even as commercial viability for such chemistries may take time,” said ICRA.
For Dewan, multiple challenges exist on the road to establishment of a cell manufacturing ecosystem, primary ones being technology complexity, high capital intensity and raw material availability. “The ability of battery manufacturers to enter into agreements/alliances with players across the value chain to mitigate these risks, coupled with the creation of a robust framework for recycling would remain key,” he adds.
