This chapter examines the battery technology of EVs in the Indian context. Battery technology dictates the materials used in manufacturing. Lithium-ion batteries typically use lithium for the cathode and graphite for the anode. Ongoing global R&D aims to mitigate lithium scarcity, potentially changing future demand for critical minerals. India lacks reserves of key battery materials such as lithium, nickel, and cobalt. To address this, the Indian government is promoting EV battery reuse and recycling. Recycling spent batteries recovers valuable metals like lithium, cobalt, nickel, and manganese, along with by-products like graphite, iron, copper, and aluminum. Beyond manufacturing, opportunities exist in battery management software for performance monitoring. Recent EV battery fires and voluntary recalls by EV producers have highlighted the need for improved safety and quality standards.
