New Flow Battery Stores 4 Electrons for Better Energy Storage
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 new battery technology achieves ultra-high energy density and exceptional stability through innovative molecular design, enabling better renewable energy storage solutions for the power grid.
📈 One key stat: The new battery technology maintained 100% capacity retention after 5,200 cycles while achieving 90 Ah/L volumetric capacity, marking a significant advance in energy storage capabilities.
💬 One key quote: “Increasing the number of electron transfers per molecule can enhance energy density and lower electrolyte costs without increasing concentration.”
1️⃣ The big picture: Scientists have developed a breakthrough battery technology that makes renewable energy storage more practical and efficient. This new aqueous organic flow battery (AOFB) uses an innovative molecular design that allows for higher energy density and remarkable stability. The key advance is a specially designed molecule that can store four electrons instead of the typical one or two, while remaining highly soluble in water and stable during repeated charge cycles. This development addresses major challenges that have limited the commercial adoption of flow batteries for grid-scale energy storage.
2️⃣ Why is this good news: Grid operators and utilities can now access more efficient and practical energy storage solutions to help integrate renewable power sources. The technology’s high stability and energy density mean fewer materials are needed, potentially reducing costs of large-scale energy storage systems. The battery’s ability to operate across a wide temperature range (10-60°C) makes it practical for real-world deployment. Additionally, the aqueous nature of these batteries makes them inherently safer than many current alternatives.
3️⃣ What’s next: Researchers will need to scale up the technology from laboratory demonstrations to commercial-sized systems. Engineering work will focus on optimizing the battery design for manufacturing and real-world grid applications. Cost analysis and further durability testing under various operational conditions will help determine the technology’s commercial viability. Partnerships with industry players will be crucial for bringing this promising technology to market.
