Friction-Based Battery Recycling Extracts Metals Without Toxic Waste
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: A groundbreaking friction-based recycling method called tribocatalysis now extracts valuable metals from spent lithium-ion batteries without toxic chemicals or high temperatures, offering a sustainable solution for the growing battery waste problem.
📈 One key stat: Tribocatalysis operates without the extreme heat required by traditional methods, significantly reducing the environmental impact of battery recycling while efficiently recovering valuable materials.
💬 One key quote: “By efficiently recovering valuable materials from old batteries and reducing associated waste and pollution, tribocatalysis could pave the way for more sustainable battery industry practices.”
1️⃣ The big picture: Scientists have developed tribocatalysis, a revolutionary friction-based method to recycle lithium-ion batteries without harmful chemicals or high temperatures. This technique leverages friction between surfaces to create chemical reactions that extract valuable metals like lithium and cobalt from spent batteries. Current recycling methods – pyrometallurgy and hydrometallurgy – require substantial energy or release toxic gases, creating significant environmental hazards. Tribocatalysis addresses these issues by providing a cleaner, more efficient approach that works specifically on battery cathodes, where energy storage takes place. Computer models combined with experimental data have validated this promising technique.
2️⃣ Why is this good news: Tribocatalysis tackles two critical challenges at once: preserving scarce resources and protecting the environment. The process eliminates the need for extreme heat or toxic substances typically required in battery recycling, making it both safer and more cost-effective. This innovation comes at a perfect time as global demand for electric vehicles and renewable energy systems continues to rise dramatically. The approach recovers valuable metals without generating additional pollution or hazardous byproducts. By creating a circular economy for battery materials, tribocatalysis can reduce pressure on new mining operations while extending the lifespan of these essential resources.
3️⃣ What’s next: Researchers must now scale up the tribocatalysis process for industrial implementation while conducting further studies on its economic viability. Companies need to develop specialized equipment that can efficiently perform this friction-based recycling at commercial volumes. Industry partnerships will be crucial for bringing this promising technology from laboratory success to widespread adoption.
