The History of Sodium-ion Batteries


Once upon a time, in the world of batteries, there was a lesser-known contender called the Sodium-ion Battery (NIB). Its history dates back to the 1970s and 1980s when scientists started exploring sodium intercalating materials. At that time, they were just as excited about NIBs as they were about their more popular cousin, the Lithium-ion Battery (LIB).

However, as time went on, the spotlight shifted, and the focus turned more towards LIBs. These lithium-powered wonders were commercialized in the 1990s by Sony, who utilized a material invented by the brilliant Prof John Goodenough. It was a game-changer! LIBs were initially optimized for consumer electronics, but they soon spread their wings and dominated various industries, with the automotive sector being their largest playground.

As LIBs took center stage, the interest in NIBs declined. But don’t worry, our story doesn’t end here! In the early 2010s, NIBs experienced a remarkable resurgence, and it was all thanks to the increasing cost of lithium-ion battery raw materials. Suddenly, people remembered the potential of NIBs, and their journey back to the limelight began.

Here’s where things get exciting! NIBs and LIBs are quite similar in terms of their material components and manufacturing processes. In fact, NIBs can be thought of as a “drop-in” replacement for LIBs. The main difference lies in the charge carrier ion, which switches from lithium (Li+) to sodium (Na+).

But why the sudden interest in NIBs again? Well, cost plays a crucial role. Up to 80% of the cost of manufacturing a LIB cell comes from materials, and companies are always on the lookout for ways to reduce costs. Sodium comes to the rescue! It’s the sixth most abundant element on our planet, found in seawater and minerals. Unlike lithium, which is geographically limited in terms of reserves, sodium is more widely available.

The switch to NIBs becomes even more enticing when we look at the price comparison between lithium and sodium compounds. The cost of lithium carbonate (Li2CO3) is around USD 6600 per metric ton, while sodium carbonate (Na2CO3) costs just USD 60 per metric ton! That’s quite a difference, right? It makes producing NIBs a fraction of the cost of LIBs.

Now, let’s talk about safety. NIBs offer a potential safety benefit over LIBs. Safety is always a priority, especially when it comes to batteries. So, the promise of a safer alternative is music to our ears.

In a nutshell, NIBs have two main superpowers: cost-effectiveness and safety. They can also come close to matching the performance of LIBs while offering the lower cost associated with traditional lead-acid batteries. It’s like getting the best of both worlds!

But let’s be honest; NIBs are not perfect. They may not currently have the energy density of LIBs, but there’s hope for the future. As this technology matures, it might not be long before NIBs bridge the energy density gap and become a genuine contender.

As we conclude our fascinating tale of NIBs, we want to mention a company that’s deeply passionate about advancing sodium-ion battery technology—Nadion Energy. They are at the forefront of NIB development, working tirelessly to unlock the true potential of this exciting technology. With a focus on cost, safety, and performance, Nadion Energy aims to revolutionize the battery industry and power a greener, brighter future.

So there you have it, the incredible history and potential of sodium-ion batteries, brought to you in an engaging and easy-to-understand story. Remember, the journey of NIBs is far from over, and the future holds exciting possibilities!

  1. Dear Nadion Energy,

    Visiting your website I have checked your powerful sodium ion batteries and I am looking for a 12V 60-100Ah solution for my residential solar panel system.
    May I ask you to send me a product brochure about your 12V 30Ah sodium ion battery?
    Do you have a warehouse in the EU?
    Can you ship/deliver to EU countries?

    Thank you in advance for your help and response!
