Creating the circular economy
On a global scale, several hundred gigawatt-hours (GWh) to several terawatt-hours (TWh) of battery capacity from Electric vehicles will be discarded by 2030. Recycling these batteries prematurely would be a missed opportunity, as they retain at least 80% of their original capacity. With a wide range of applications capable of utilizing these batteries for another 5-8 years, we can maximize their potential. Notably, repurposing and reusing these batteries also contribute to sustainability by reducing the overall negative impact of EVs. As 11-18% of the lifetime emissions from an EV stem from battery manufacturing, our approach helps minimize environmental consequences
Nunam has been driving positive change in the electric vehicle space by implementing battery design changes that bolster sustainability across the entire value chain. Through our innovative solutions and services, we extend battery lifespan in first-life applications, optimize resource management, and facilitate seamless second-life adoption. Ensuring recyclability at the end of the battery’s life is a key aspect of our commitment to sustainability. With these innovative design enhancements, Nunam has been leading the charge towards cleaner and sustainable electric vehicles.
Second-life batteries refer to used batteries from electric vehicles or energy systems that are repurposed for other applications. Second-life batteries extend the useful life of lithium batteries, thereby increasing resource utilization and reducing e-waste. Repurposing provides a cost-effective solution for energy storage applications and also avoids the requirement to manufacture new batteries.
After the real end of life, Nunam takes back the batteries from customers and sends them to recycling. One of the major challenges in lithium battery recycling is the cost of reverse logistics, which is leading to hazardous informal recycling of the batteries. With the additional revenue generated from selling the second life batteries, the cost of reverse logistics can be subsidized to make sure the batteries are recycled and the extracted minerals can enter the lithium value chain again.
The circular economy of lithium batteries faces several challenges that must be addressed to promote more sustainable and responsible use of these batteries. Nunam ensures that the second life batteries are safe and reliable, and has developed state of the art processes for testing, grading, and repurposing the batteries. Nunam is working towards building robust business models together with multiple stakeholders in the EV and battery ecosystem for better commercial viability and to secure supply of second life batteries.
