How to dispose of old batteries from redundant electric vehicles? The good news: we can harvest their valuable parts to make new ones. In the future, electric vehicles may prove to be a valuable secondary resource for critical materials, and it has been argued that high cobalt-content batteries should be recycled immediately to bolster cobalt supplies”, the study says. “If tens of millions of electric vehicles are to be produced annually, careful husbandry of the resources consumed by electric-vehicle battery manufacturing will surely be essential to ensure the sustainability of the automotive industry of the future.” The study says an EV battery – much like a battery in a mobile phone – loses some of its effectiveness during its life cycle, but can still hold up to 80% of its power. While it’s not suitable for continued road use, it can be adapted for other purposes. Banks of old EV batteries could store power: they could be used to store energy to feed into the electricity grid or directly into buildings. In Japan the Toyota car company has pioneered a scheme which hooks up old EV batteries with solar panels to power convenience stores.
