An anonymous reader shares a report: India is set to begin mass-producing electric-vehicle batteries within 18 months, a step hailed as a leap towards industrial self-reliance. Yet the structure of this new industry looks troublingly familiar, echoing a pattern of dependence that has long marked India's economy. Nowhere is this dependence clearer than in the heft of intellectual property. The portfolios of India's largest battery-makers, Amara Raja and Exide, contain just seven patents combined. This pales in comparison to the industry's giants: China's CATL sits on a hoard of over 43,000 patents, while South Korea's LG Energy Solution possesses some 70,000. Having largely missed the global lithium-ion boom, India's established lead-acid manufacturers built a business model on licensing technology rather than inventing it. This long-standing habit is now reflected in deals that create deep technological dependency. A 2022 agreement between Exide and China's SVOLT, for example, calls for SVOLT to not only transfer intellectual property but also to oversee plant construction, supply the equipment and integrate the factory into its own Chinese supply chain. Amara Raja's deal with Gotion High-Tech in June 2024 follows a similar template.Read more of this story at Slashdot.
