Ever wondered why big EV makers haven’t considered sodium-ion batteries? Well, you are in luck because Indi Energy is bringing you the answers!
We have often been asked, “Why have automobile manufacturers not considered sodium-ion batteries for their electric cars?” If this were a few years ago, the answer to that question would have been straightforward: Low energy density = big battery size. This explains why lithium-ion batteries have played such a pivotal role in the rapid growth of the electric vehicle (EV) market. Their high energy density, efficient power delivery, and proven reliability have made them the go-to choice for powering electric cars. However, as concerns about the environmental impact of lithium mining and extraction continue to escalate, it is becoming evident that a shift towards more sustainable alternatives is necessary. Enter sodium-ion batteries, a promising new solution that offers the potential to revolutionize the EV industry while addressing environmental concerns. And times are changing; JAC in China has just put out the world’s first EV powered by sodium-ion batteries.
What are the issues that kept EV makers from
choosing sodium ion batteries?
Firstly, sodium-ion batteries have a low energy density, which means that if EVs had these installed in them, the size of the Na-ion batteries would have to be pretty big compared to lithium-ion batteries, adding more weight to the car.
Secondly, unlike lithium-ion batteries, which are at their peak in terms of power delivery and have been undergoing refinement and development for more than 50 years, sodium-ion batteries are in the early research and development phases. Look at CATL, which is planning to put out batteries that can reach 160 Wh/kg, and that’s just one instance. But for a new technology that is still undergoing R&D, it is very impressive!
Thirdly, lithium-ion batteries have undergone a series of tests to ensure their viability and safety (more on that below), and your sodium-ion batteries are just getting started. So, you can pretty much guess the picture!
And of course, we cannot ignore the supply chain that exists for lithium-ion batteries. Manufacturing infrastructure for sodium-ion batteries does not require huge investments, as fabrication of sodium-ion batteries can be carried out using the existing infrastructure for lithium-ion batteries, but we still need to establish a supply chain for sodium-ion batteries, which is already underway.
So what has changed? Why are sodium ion batteries gaining more prominence?
There are quite a few energy storage manufacturers that are close to starting the mass production of sodium-ion batteries. Take us, for example, Indi Energy. We are going to be starting the mass production of our Na-ion batteries, which are powered by the world’s highest-performing hard carbon that is made out of biowaste and agricultural waste. It took us a few years, but we are almost there. Indi Energy has addressed all of the issues that were preventing sodium-ion batteries from competing with lithium-ion batteries. The ball is now in the court of all these big EV makers; they need time to adapt to sodium-ion batteries, and once they do, the game is on!
Cheaper with Long cycle life, fast charging, and rapid discharge, along with a power density that is similar to the commercialized Li-ion batteries. But the biggest positive is that Indi Energy’s sodium-ion batteries are non-flammable! That’s right! Say goodbye to those pesky little lithium-battery fires that can spontaneously burst into flames for 2-3 days like this one. PS: It’s the Rimac Concept One, the world’s first electric supercar!
The environmental impact of lithium mining and extraction has become a growing concern, and rightly so! The EV market is going to change soon with sodium-ion batteries. With the recent developments, we are going to see more and more EVs with sodium-ion batteries! As they say, the story has just begun!
