Millions of electric car batteries will retire in the next decade. What happens to them? | Environment

A tsunami of electric vehicles is expected in rich countries, as car companies and governments pledge to ramp up their numbers – there are predicted be 145m on the roads by 2030. But while electric vehicles can play an important role in reducing emissions, they also contain a potential environmental timebomb: their batteries.

By one estimate, more than 12m tons of lithium-ion batteries are expected to retire between now and 2030.

Not only do these batteries require large amounts of raw materials, including lithium, nickel and cobalt – mining for which has climate, environmental and human rights impacts – they

Why Electric Cars Have Regular 12V Car Batteries

Manufacturers are investing huge sums into battery technology to maximize the range and performance of new electric cars. However, if you pop the hood of a modern EV, you might find a regular old 12-volt car battery. That may be a confusing experience, but fear not — we’ll explore why that’s there, and uncover the secrets of an electric car’s 12 volt systems while we’re at it.

The 12V battery nestled in a Tesla Model 3. These batteries often fail in EVs, as they don’t draw high current from the lead-acid battery on starting like an ICE does. It’s believed this high current draw regularly breaks up deposits that build up on the plates of the battery, helping it last longer. EVs don’t do this, and 12V battery failures are common.

Most electric cars get around with just one big, high voltage battery pack full of rechargeable lithium cells that drive the motor. But, EVs also have a regular old 12 volt lead-acid

Electric vehicles: recycled batteries and the search for a circular economy

Few people have had the sort of front-row seat to the rise of electric vehicles as JB Straubel.

The softly spoken engineer is often considered the brains behind Tesla: it was Straubel who convinced Elon Musk, over lunch in 2003, that electric vehicles had a future. He then served as chief technology officer for 15 years, designing Tesla’s first batteries, managing construction of its network of charging stations and leading development of the Gigafactory in Nevada. When he departed in 2019, Musk’s biographer Ashlee Vance said Tesla had not only lost a founder, but “a piece of its soul”.
