However, lithium-ion batteries still dominate the market due to their relatively high performance and established manufacturing processes.
2. Global Demand for Lithium
Lithium is the key material in the production of Li-ion batteries. As the world shifts to electric mobility and renewable energy storage solutions, lithium has become one of the most sought-after commodities. The demand for lithium is expected to increase dramatically over the next few decades, with EVs being the primary driver of this growth.
a. Rising Demand for Lithium
The global demand for lithium has surged as electric vehicles become mainstream. According to estimates, the demand for lithium could increase by more than 700% by 2030, as more countries, including India, aim to electrify their transportation sectors. The high energy density of lithium-ion batteries makes them the preferred choice for EVs, and as more automakers roll out electric models, the pressure on lithium supply chains continues to grow.
b. Lithium Reserves and Production
Lithium is primarily extracted from two sources: hard rock deposits and lithium-rich brine pools. The top lithium-producing countries are Australia, Chile, and China, which collectively account for a significant portion of global lithium production. While the world’s known lithium reserves are abundant, the ability to extract, process, and refine lithium efficiently remains a challenge.
3. India’s Lithium Challenges
India’s ambition to transition to electric mobility faces a critical roadblock – its lack of domestic lithium reserves. While India has made significant strides in the development of its EV ecosystem, it currently relies heavily on imports for the raw materials needed for battery production, including lithium.
a. Limited Domestic Lithium Reserves
India’s domestic lithium resources are scarce, and currently, no major lithium deposits have been identified in the country. According to the US Geological Survey (USGS), India’s lithium reserves are minimal compared to other countries. In fact, India’s lithium production is almost non-existent, making it heavily dependent on imports to meet the growing demand for EVs.
b. Import Dependence
India’s reliance on lithium imports puts the country at a disadvantage in its pursuit of self-sufficiency in EV production. The primary sources of lithium imports for India include countries like Australia, Argentina, and Chile. However, geopolitical factors, supply chain disruptions, and fluctuating prices pose risks to the stability of these supply lines.
4. India’s Efforts to Secure Lithium Reserves
In response to the challenges of lithium dependency, India has taken several steps to secure its position in the global lithium supply chain. These efforts involve exploring domestic lithium mining opportunities, forging international partnerships, and investing in research and development.
a. Exploration of Domestic Reserves
In recent years, India has started exploring its domestic lithium potential. In 2020, the Geological Survey of India (GSI) confirmed the discovery of lithium reserves in the Reasi district of Jammu & Kashmir. Although these reserves are still in the early stages of exploration, they could prove to be a critical asset for India’s future EV ambitions. The Indian government is keen on developing this resource and potentially opening up domestic lithium production to reduce reliance on imports.
b. International Partnerships and Investments
India has also sought international partnerships to secure its lithium needs. The government and private sector companies are actively investing in lithium projects abroad. For instance, India’s state-owned mineral exploration company, Mineral Exploration Corporation Limited (MECL), has been involved in exploring opportunities in countries with rich lithium reserves.
In addition to mining, India has also been exploring the possibility of securing long-term lithium supply contracts with global suppliers, ensuring a stable and uninterrupted flow of the critical material.
c. Recycling of Lithium-Ion Batteries
Recycling is another area where India is looking to reduce its dependence on raw lithium imports. Battery recycling technology allows for the extraction of lithium from used batteries, which can be reused in new battery production. As the EV market matures, the availability of second-life lithium from recycled batteries could become a significant source of supply.
5. Policy Support and Initiatives
The Indian government has recognized the strategic importance of lithium in the context of its EV and energy storage goals. Several policy initiatives and reforms have been introduced to support the growth of the EV ecosystem and reduce India’s reliance on lithium imports.
a. National Electric Mobility Mission Plan (NEMMP)
India’s National Electric Mobility Mission Plan (NEMMP) aims to promote the adoption of electric vehicles across the country. The government has introduced several incentives, including subsidies for electric vehicles and charging infrastructure, to accelerate the transition to electric mobility. However, for this mission to be successful, securing a stable supply of lithium and other critical materials remains a fundamental challenge.
b. Atmanirbhar Bharat (Self-Reliant India)
Under the Atmanirbhar Bharat initiative, India has taken steps to boost domestic manufacturing capabilities in key sectors, including electric vehicles and batteries. The government has encouraged private investment in the EV supply chain, including battery manufacturing and recycling, to reduce dependence on imports.
