World : Article-End-Of-Life Electric Vehicle Batteries: Recycling or Second-Life?

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. By 2020 we will already have around 14 GWh, or 102,000 tonnes of Li-ion batteries retiring from EVs per year. With the rapid adoption of EVs, the total amount of EV batteries reaching end-of-life is expected to reach 7.8 million tonnes per year by 2040. When an EV battery is reaching its end-of-life of its vehicle service, the battery can either be repurposed for a second-life in alternative applications or recycled to obtain the raw materials. Unlike batteries used in consumer electronics such as our laptops and mobile phones, the batteries retired from electric cars could still retain 70-80% of their initial capacity. Those batteries cannot satisfy the requirements for use in EVs anymore, for example when the loss of battery capacity limits the driving range of the electric car, but they could provide sufficient capacity for less-demanding applications such as stationary energy storage in their 'second-life'. Global EV manufacturers including Nissan, Renault, BMW, Volkswagen, BYD and so on have been exploring various usage scenarios for second-life EV batteries from residential, to commercial and grid-scale energy storage applications.
