Northvolt's Battery Recycling - Prof. Emma Nehrenheim | Battery Podcast

#BatteryRecycling #Northvolt #Electromobility
As #supply #chains of #battery #materials are fragile, #raw #materials are getting #expensive. At the same time vast amounts of old, done (#cobalt-#rich) #batteries are now available for a #circular #economy. That's why #battery #recycling is getting more and more attention! Plus, the #EU #Battery Regulation now forces #battery makers to strictly follow #sustainability rules, anyways. Let's have a look at the #recycling plans of Sweden's largest #battery maker #Northvolt.

Our podcast guest on this episode is Prof. #Emma #Nehrenheim. She is a Professor for #Environmental #Engineering at #Mälardalen #University. As an academic #researcher and industry innovator she wants to deliver the world's #greenest #battery for her employer. She summarizes her #innovation efforts as follows: “It’s clear to me that batteries are the enabler to so much of [my] vision for #electrification, but there are better and worse ways to build a battery from an #environmental perspective."
The "better way" of "#building a #battery" includes a functioning #recycling #strategy. Fortunately, scienists optimized two very sophisticated paths of how to recycle a useless, done battery: They are based on either (1) #pyrometallurgic #recycling and/or (2) #hydrometallurgic #recycling #technologies. #Pyrometallurgic #techniques are already frequently used to get back common #battery #materials. But this comes with an enormous energy input. #Northvolt‘s #hydrometallurgical recycling technology on the other side retrieves #lithium, #nickel, #cobalt, and other metals from its #black #mass. The process produces these metals at a rather high grade so they can be used to create new #batteries afterwards. The hydromet technology works with all #formats and #chemistries of #lithium-#ion #batteries and can recover almost all #batteries’ materials. The following high-performing metal products produced from this #black #mass come with battery-grade purity levels: (1) #Lithium #carbonate, (2) #Cobalt #sulfate, (3) #Nickel #sulfate, (4) #Manganese #carbonate.

Thanks for the chat, Prof. Emma Nehrenheim 🇸🇪🔋

Ich denke es wird nicht ohne staatliche Kontrollen funktionieren. Die Zertifikatsflut auf den Produkten ist schon jetzt sehr unübersichtlich für den Verbraucher. Wir sollten solche Recycling-Firmen/Scheideanstalten staatlich fördern falls sie nicht gewinnbringend arbeiten können. Und die Mittel dafür beim Kauf von Batterien erheben. Ähnlich wie bei der Mineralölsteuer. Das wirkt sich dann auch nicht auf den Wettbewerb aus und bringt uns neue Arbeitsplätze.

You should interview Dr.Mylad who is building Zinc ion batteries in Europe

Great interview, thank you!

Fantastic interview, thank you.

The problem with recycling is, it has a bad reputation.
Old electronics ending up in Afrika, cables being burned for copper wire
Plastics stating they can be recycled, but then when I bring anything other than PET or PEHD to my local recycling yard, they decline being able to recycle it.
And that's a problem with all recycling. Recycling has to have a econimic gain, otherwise companies cheat.

This was super interesting 🔬

What impact would a wind machine that delivers power 24/7 in the battery industry??

Standardisation of batteriry physical dimensions could be key to recycling and reuse. A 12 V acid battery is one cell but an EV battery has multiple cells. Reusing the good EV cells and recycling the bad is where we should be looking. If a standard format could be agrreed upon then this Far West of batteries could be be avoided.
