The Second-Life of Used EV Batteries

When an electric vehicle (EV) comes off the road, what happens to the vehicle battery? The fate of the lithium ion batteries in electric vehicles is an important question for manufacturers, policy makers, and EV owners alike. The economic potential for battery reuse, or second-life, could help to further decrease the upfront costs of EV batteries and increase the value of a used EV. Given the growing market for EVs, second-life batteries could also represent a market of low-cost storage for utilities and electricity consumers. But in order to enable widespread reuse of EV batteries, policy will play an important role in reducing barriers and ensuring responsible, equitable, and sustainable practices. Read more >

How Long Will My EV Battery Last? (and 3 Tips to Help it Last Longer)

For an electric vehicle (EV), low battery fear can contribute to what’s known as ‘range anxiety’, an often cited barrier to wide-spread EV adoption. But, as the market for EVs continues to develop and technology improves, the lithium batteries in electric vehicles are going further for far longer.  In this blog, we unpack the lifetime of lithium batteries for electric vehicles, provide some tips on how to maximize battery life, and explain why the battery of an EV may well outlive the car.

A Quick Guide to Battery Reuse and Recycling

From scooters to motorcycles, sportscars, school buses, trucks, trains, and even planes, it seems we are entering the era of electrified mobility.  This has been due in large part to the rapidly falling costs and improving performance of lithium-ion batteries. Better batteries are enabling an increasingly wide array of electric personal, light, and heavy-duty vehicle technologies. The growth in deployments of lithium batteries will inevitably create a large flow of retired or used batteries.  By 2030, analysts predict that retirements could exceed half a million vehicles annually or over 2 million metric tonnes of batteries per year.
