Second Life Batteries


India aims to be a 100% electric vehicle (EV) nation by 2030. Home to 14 of the 20 most polluted cities in the world, EVs that use lithium-ion batteries (LIB) would reduce emissions from the prevalent internal combustion engine powered vehicles that cause two-thirds of air pollution in urban India. The EV-driven transformation would however result in a large volume of used LIBs. Nunam offers repurposed LIBs that come with high energy-to-weight ratios, low self-discharge rate, no memory effect, and reduced storage costs by 30-70% with overarching contributions to a circular economy, while subsidizing vehicle cost, expensive mineral recovery and reducing pressure on need for virgin minerals.
