While IC engine based vehicles are being phased out because of stringent global emissions standards, Population of Electric Vehicles are growing exponentially. With the rapid adoption of electric vehicles (EVs), the demand for Li-ion batteries will grow significantly in the coming decades. In the meanwhile, as EV batteries begin to reach their end-of-life, we will see an exponential growth of retired Li-ion batteries coming out of vehicles.
The total amount of EV batteries reaching end-of-life is expected to reach 7.8 million tonnes per year by 2040, according to a study published by IDTechEx. It is therefore, crucial that appropriate recycling batteries must be developed and adopted. At the same time, the recycling methods should have less or no impact on the environment. In this lecture, various batteries technologies and battery recycling methods are discussed with focus on their life cycle assessment.
