The global transition towards sustainable transportation has become a driving force in the shift from fossil fuels to renewable energy sources. This move is crucial for achieving worldwide decarbonization goals, with electric vehicles (EVs) playing a pivotal role. At the heart of this transformation are lithium-ion batteries (LIBs), which have come to the forefront as key enablers of a cleaner and more sustainable future.
In 2021, LIBs dominated the electrochemical energy storage sector, claiming an impressive 90.9% of the global market share. Their superiority in terms of energy density, extended lifespan, and enhanced electrical and chemical characteristics have made them the preferred choice, surpassing conventional alternatives like lead-acid batteries. However, as the electric mobility sector expands, concerns have arisen regarding the sustainability and security of raw mineral supply. Elements such as lithium (Li) and cobalt (Co), which are vital for LIB production, have become central to this conversation. Additionally, the improper disposal of spent LIBs poses environmental and health risks, underlining the urgency for efficient recycling.
The growing electric mobility market is driving a surge in demand for batteries, leading to increased requirements for primary raw materials such as lithium, graphite, nickel, manganese, and cobalt. However, despite the widespread adoption of LIBs, these raw materials remain concentrated in a few countries, emphasizing the need for India to secure its raw material independence, especially in the face of geopolitical uncertainties.
A potential solution to this challenge lies in the recycling of valuable materials within discarded LIBs. By adhering to recycling targets set by Indian regulatory bodies, up to 92% of material loss for lithium, cobalt, and nickel can be averted based on average battery composition. Recycling efforts have the potential to provide significant percentages of the lithium, nickel, and cobalt required for LIB production in India. However, actual statistics reveal a gap between aspiration and reality, with alarmingly low rates of used LIB collection and recycling. India’s proactive approach in establishing stringent recycling regulations can bridge this gap, aligning the industry with sustainable practices.
As the average lifespan of LIBs spans around 8 to 10 years, the accumulation of used batteries is inevitable, emphasizing the role of recycling in managing this growing challenge. Recycling is more than an environmental imperative; it is a strategic move that safeguards resource security, mitigates pollution, and fortifies supply chain resilience.
India, a nation poised for monumental growth, holds a remarkable opportunity to shine on the global stage by attracting substantial investments in battery recycling. The cumulative potential for reusing batteries paints a promising picture, with an estimated volume of 49 GWh by 2030.
India’s future envisions a collective capacity of approximately 600 GWh of lithium-ion batteries across various sectors by 2030. A significant portion, around 128 GWh, is projected to undergo recycling, with nearly 59 GWh sourced from the Electric Vehicle (EV) sector. This trajectory is nothing short of remarkable and has the potential to make India a global leader in battery recycling.
India’s journey towards battery recycling and reuse is driven by several key factors:
India’s waste management policy draft takes a pivotal stance on battery recycling, but it’s essential to focus on battery reuse, an often-overlooked facet that holds paramount significance in forging a true circular economy. The unique battery chemistry in use plays a pivotal role in harnessing the full economic potential of battery recycling, requiring inventive solutions that make recycling not only environmentally sound but also economically viable.
Central Pollution control board’s EPR portal for Battery waste management saw an encouraging response from EV manufacturers. Over 59 EV manufacturers, including MG Motor, Ola Electric, Ather Energy, Tata Motors, and Mahindra & Mahindra, have signed up to recycle lithium-ion battery waste.
A few other notable initiatives from organizations in India include:
Recycling lithium-ion batteries is a sustainable approach to conserve resources, reduce environmental harm, and minimize e-waste. As recycling technologies advance, they play a key role in extending battery lifecycles and reducing their environmental impact. By supporting responsible choices and recycling efforts, we can contribute to a cleaner and more sustainable planet.
