Northvolt introduces the first fully recycled electric car battery

A totally recycled electric car battery: a certain goal, uncertain timing. Northvolt starts a mad rush.

Recycled electric batteries

READ THIS IN:

A Swedish company called Northvolt announced to have successfully recycled a lithium-ion battery cell containing a nickel-manganese-cobalt (NMC) cathode, using only metals recovered from battery waste.

The company says its "Revolt" recycling program has become the first to recycle an electric car battery using 100% reused materials.

All of Northvolt's recycling and manufacturing measures took place at one site, within its laboratories in Västerås, Sweden. And it's a significant breakthrough for the global battery industry, as it seeks to make the nascent electric car industry truly sustainable.

The bad news is that today we are in a bad way with the recycling of electric car batteries

Tesla vehicles themselves (the world's number one electric car manufacturer) are unsustainable because they require intensive extraction of raw materials to produce lithium-ion batteries. Don't get me wrong: Tesla has done its best for sustainability so far. It is that in general current manufacturing practices are counterintuitive and unwise in the long run.

There is work to be done before we can call these electric cars green (and it has to be done by 2035).

The good news is that it can be done

The recycling process can recover up to 95% of metals in electric batteries, maintaining a level of purity comparable to the "virgin" material. This is what the Chief Environmental Officer states in the press release Emma Nehrenheim by Northvolt. The next step is to find out if Northvolt and other companies can develop these new recycling processes in preparation for the second "wave" of dead batteries.

The cycle of electric cars now on the market will run out within 5-7 years). In total, 250.000 tons of electric vehicle batteries will reach end of life in 2030.

How Northvolt's recycling process works

Recycled cobalt, manganese and nickel used in the new battery cell were collected from the battery waste. How? Through a low energy hydrometallurgical treatment. The treatment involves the use of an aqueous solution to isolate the metals and empty them of remaining impurities.

Now the result, a fully recycled electric car battery, has to go from laboratory to mass production. More time needed: Northvolt expects to produce cells with 50% recycled material on an industrial scale by 2030.

In line with this goal, the company's large-scale Revolt Ett recycling facility in Skellefteå, Sweden will be expanded to make room for recycling of 125.000 tons of batteries annually.

This expansion will make Revolt Ett the largest battery recycling plant in Europe, as well as the only large-scale recycling factory capable of reusing lithium, cobalt, manganese and nickel, among other metals. We are talking about 30 GWh of battery production every year. Other metals recovered from Revolt Ett will include aluminum, copper and plastics, and all of these can be recycled into production streams via third-party activities.

Electric challenges and opportunities

The electric car revolution is picking up speed, and a commitment to the circularity of production processes is crucial. In August, Tesla said it could recycle 92% of battery cell materials, after recovering 1.300 tons of nickel in 2020.

The only out of tune string? The energy that powers the electric: that's where you have to hit hard. Ok the columns, but if to recharge a battery (even if totally recyclable) electricity is generated in fossil fuel plants, we are always there.
