Batteries are the most expensive component of an electric vehicle. If the battery pack is damaged, defective or simply old, this can lead to the vehicle being written off prematurely.
Increasingly scarce and valuable resources, such as lithium and water, are needed to make these batteries. Despite this, they are often not designed for ease of repair, reuse or recycling. This has significant environmental impacts, ranging from the mining for materials and the water and energy used in making new batteries and vehicles, through to the hazardous waste from discarded batteries.
