Old batteries can be source of new energy

(Climate News Network, 24 Feb 2020) How to dispose of old batteries from redundant electric vehicles? The good news: we can harvest their valuable parts to make new ones.

LONDON, 24 February, 2020 − Driving an electric-powered vehicle (EV) rather than one reliant on fossil fuels is a key way to tackle climate change and improve air quality − but it does leave the old batteries behind as a nasty residue.

New technologies give rise to their own sets of problems. The all-important battery in an EV has a limited life span – due to high operating temperatures, changing discharge rates and other factors, batteries in EVs in use today are unlikely to last for more than 10 years.

The question is what to do with all those batteries once they have reached the end of their operating life. The dumping of electronic or e-waste – made up of old computers and other everyday equipment − is already a massive worldwide problem: EV industry analysts say similar difficulties could develop when EVs and their batteries reach the end of their lives.
