New Carbon-Capturing Batteries Store Energy While Reducing Emissions
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: New lithium-CO2 batteries developed by University of Surrey scientists capture carbon dioxide while storing energy more efficiently, potentially offering a dual solution for clean energy storage and emissions reduction.
📈 One key stat: The new battery can reliably operate for more than 100 charge-discharge cycles, a crucial milestone for practical applications of this carbon-capturing technology.
💬 One key quote: “What’s exciting about this discovery is that it combines strong performance with simplicity. We’ve shown that it’s possible to build efficient lithium–CO2 batteries using affordable, scalable materials – no rare metals required,” said Dr. Daniel Commandeur.
1️⃣ The big picture: Scientists at the University of Surrey have created an improved lithium-CO2 battery that simultaneously stores energy and captures carbon dioxide. This innovative battery technology addresses previous limitations by using a low-cost catalyst called caesium phosphomolybdate instead of expensive rare materials like platinum. Through comprehensive testing and computer modeling, researchers found that this simple modification allows the batteries to store more energy, require less charging power, and operate reliably over multiple cycles. These ‘breathing‘ batteries could eventually outperform conventional lithium-ion batteries while contributing to greenhouse gas reduction.
2️⃣ Why is this good news: The discovery represents a potential two-for-one solution to urgent climate challenges – clean energy storage paired with carbon capture. By developing batteries that use affordable, accessible materials rather than rare metals, researchers have cleared a major hurdle for practical implementation. The technology shows promise for applications ranging from electric vehicles to industrial emissions reduction. Beyond Earth applications, these batteries could prove valuable for Mars missions, where the atmosphere is 95% carbon dioxide, potentially turning an environmental liability into an energy asset. This demonstrates how climate solutions can also drive space exploration capabilities.
3️⃣ What’s next: Researchers need to continue optimizing how these catalysts interact with electrodes and electrolytes to further improve performance. Scaling up production while maintaining the demonstrated efficiency remains a critical challenge. With additional development, these lithium-CO2 batteries could become a practical, widespread option for clean energy storage while helping reduce atmospheric carbon.
