Research on Recycling and Recovery of Lithium-Ion Battery Cells
Description
To propose a proof-of-concept product: a Universal Battery Management System for second-life EV batteries.
Current battery sorting is manual/informal. The project pivots to an unserved second-life BMS market gap.
Backup power for telecom towers, rural microgrid storage, EV charging buffer, e-rickshaws, industrial UPS systems.
Abstract
This B. Tech project, undertaken on the Entrepreneurial Track, presents a semester-long inves- tigation into the lithium-ion battery (LIB) recycling and reuse value chain in India. The study began with the problem of automated battery sorting and followed a field-driven methodol- ogy involving visits to a hydrometallurgy equipment manufacturer in Faridabad, the Servotech lithium battery assembly plant, and the industrial cluster in Bhiwadi, Rajasthan. Insights were further strengthened through interactions with industry leaders, including Bharat B Mehta (Reliance Industries), Pravin Saraf (Exide Energy), and the Vice Chairman of JBM Auto, along with engagement with the startup Nunam. The project also received external validation through a grant at the Delhi Startup Yuva Festival and selection for Y Combinator Startup School. A technical review of hydrometallurgical processing was conducted to build process-level un- derstanding, complemented by a detailed value proposition analysis of a black-mass production facility operating at commercial scale. The study found that battery sorting is largely managed within the informal scrap ecosystem, reducing its viability as a standalone innovation oppor- tunity. Consequently, the project pivots to the opportunity of second-life battery reuse. The proposeddirectionfocusesondevelopinga Universal Battery Management System(BMS) for end-of-life EV battery packs, enabling safe and scalable redeployment of retired EV bat- teries across stationary storage and low-power mobility applications, contributing to improved resource utilisation and supporting India’s transition toward a circular battery economy.
