Turning 17 Million Used EV Batteries Into Community Power
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: Used electric vehicle batteries retain significant power capacity that can energize homes, smaller vehicles, and even entire communities when properly repurposed.
📈 One key stat: By 2050, Australia alone will need to handle 1.6 million tonnes of EV batteries, representing a massive opportunity for repurposing and recycling.
💬 One key quote: “When a battery reaches the end of its life in a vehicle, it’s still got plenty of juice.”
1️⃣ The big picture: As electric vehicles surge in popularity globally, with over 17 million sold last year, a new challenge emerges regarding the fate of their batteries after 12-15 years of use. These massive batteries, weighing around 450 kilograms each, retain significant power capacity even after they can no longer efficiently power a car. Their potential second life includes powering homes, smaller vehicles, or even entire communities when connected together. However, realizing this potential faces a major obstacle – limited access to crucial battery performance data from manufacturers, making it difficult to assess their health and suitability for reuse.
2️⃣ Why is this good news: Used EV batteries offer tremendous value beyond their initial purpose, with up to 95% of their materials being recyclable. Even after they can no longer efficiently power cars, these batteries maintain substantial capacity for various applications. High-health batteries can power smaller vehicles, while medium-health ones can provide stationary power storage. This repurposing approach reduces the need for new battery production, decreasing environmental impact and resource consumption. The potential to power entire communities with linked used batteries presents an innovative solution for sustainable energy storage.
3️⃣ What’s next: Manufacturers need to become more transparent with battery performance data to enable effective reuse and recycling. Following California’s example and the EU’s upcoming battery passport system, Australia requires similar regulations to manage its growing EV battery inventory. Enhanced access to battery health data will help companies better assess and repurpose these valuable energy storage devices.
