Sodium ion batteries, which use the abundant element found in table salt, offer a promising alternative to lithium batteries with advantages including lower cost ($19/kWh vs $55-70/kWh), superior cold weather performance (90% capacity at -40°C), and longer cycle life (10,000+ cycles), though they have lower energy density making them better suited for stationary storage and electric vehicles rather than portable electronics where weight is critical.

China Just Unveiled New Battery That Runs on Salt and It Could Change Everything!
Added:A deal has just been signed and it could be the biggest battery agreement humanity has ever seen. 60 gawatt hours.
That is enough energy to charge every smartphone currently on Earth at the same time. And it is not lithium. It is not any battery technology you have heard about before. This is the world's largest battery manufacturer based in China. Proving something that sounds completely unbelievable. The element sitting quietly inside the salt shaker on your kitchen table could become one of the most important materials in the future of energy for the entire world.
And if that sounds hard to believe, that is because it is. But every part of this story is real. By the end of this video, you will understand exactly why this is happening and why it could change everything. Behind this moment is a story that has been building for 30 years. There were multibillion dollar bets. There were batteries that burst into flames inside people's pockets.
There was a materials problem that kept some of the brightest minds in the world stuck for four decades. And there was a price collapse so severe that it forced an entire industry to rethink its strategy from the ground up. So the question is, why is a technology that was once seen as impossible pushed aside for decades suddenly becoming a serious rival to lithium in just a few years?
And could this be a sign that lithium, the material that has dominated the technology world for the last 30 years, is starting to enter its final chapter?
Let's go back to where this entire story began. The lithium empire.
Right now, as you're watching this video, there's probably a lithium ion battery somewhere within arms reach. It could be in the phone in your hand, the laptop in front of you, the electric car sitting outside, or even the electric scooter parked by your door. Lithium ion batteries have become so deeply woven into modern life that most of us never stop to think about them. We simply expect our phones to charge overnight, our laptops to survive a full meeting, and our cars to get us where we need to go. For 30 years, lithium has delivered on those expectations so reliably that the world almost stopped questioning whether something better could exist.
Before lithium took over, electronic devices ran on nickel cadmium batteries.
They were heavy, bulky, and could only store a fraction of the energy that lithium could. The shift to lithium ion in the early 1990s was not just a small upgrade. It completely redefined what a battery could do. Energy density jumped to roughly three times what the older technology could offer. Devices became smaller, lighter, and more powerful all at once. Without that breakthrough, smartphones would not exist. Modern laptops would not exist. wireless earbuds would not exist and electric cars as we know them today probably would not exist either. The scale of that transformation is difficult to fully understand now. In 1991, a camcorder battery could only last around 1 hour. By the early 2000s, the same amount of lithium could keep a phone running for several days. By the 2010s, it could push an electric car hundreds of kilome down the highway. Every new generation of devices pushed battery engineers to squeeze even more energy out of the same chemical system and every time lithium delivered. It became the default answer for almost anything that needed portable power. So why has lithium been so effective? Think of it like this. Inside every battery, there are two electrodes, a positive side and a negative side with a liquid layer in between that acts like a highway for charged particles moving back and forth.
When you charge a battery, you're pushing those particles from one side to the other and storing them there. When you use the battery, the particles move back and that movement creates electricity. In lithium batteries, those charged particles are incredibly small.
Lithium is one of the lightest elements on the periodic table, which means you can pack a huge number of particles into a very small space. More particles means more stored energy for the same weight.
Lithium also has another advantage. It has a very strong natural tendency to push electricity through a circuit. That means you get more power from every battery cell without having to make the battery bigger. Put those two things together and you get a battery chemistry that for three decades almost nothing in the world could seriously challenge. But here's what happens when something works well for too long. People slowly stop asking whether something better might exist. Funding for alternatives starts to dry up. And once that happens, the cracks underneath the surface begin to grow until they become impossible to ignore. The secrets nobody talks about.
In 2016, Samsung launched the Galaxy Note 7. Reviews were positive.
Pre-orders exploded. Then within just a few weeks, the phone started catching fire. They burned in people's pockets, on airplanes, and on bedside tables while owners were asleep. Airlines banned passengers from bringing the devices onto flights. Samsung eventually killed the entire product line with estimated losses of around $5 billion.
The Note 7 became one of the most infamous product failures in consumer electronics history. But what most people missed was that this was not really just a Samsung engineering failure. Yes, Samsung made specific mistakes in the design of that battery.
But the core danger had always existed quietly inside nearly every lithium battery ever made. The liquid layer inside a lithium battery, the one that carries charged particles back and forth, is made from organic solvents.
Those solvents are naturally flammable.
The irony is that the materials best at moving lithium efficiently are also the materials most likely to catch fire. If a battery overheats, gets punctured, or is overcharged, that liquid can ignite.
And when one battery cell catches fire, the heat it releases raises the temperature of the nearby cells until they catch fire, too. It becomes a chain reaction that spreads from one cell to the next, like dominoes falling inside a sealed box. The scale of this problem today is genuinely shocking. Right now in New York City, fires caused by lithium batteries have surpassed electrical fires as the leading cause of death in the city's fire incidents. This is not a statistic from decades ago.
This is the reality of 2026. Then there is the cold weather problem. In freezing conditions, the charged particles inside lithium batteries do not move smoothly anymore. Instead, they begin sticking to internal surfaces and forming tiny jagged metal spikes.
These spikes can grow through repeated charging cycles until they connect both ends of the battery and create an internal short circuit. A short circuit creates heat very quickly. And heat inside a lithium battery rarely ends well. Even when those spikes are not large enough to create a short circuit, cold weather can still have a major effect on performance. At freezing temperatures, a lithium battery can lose between 20 and 40% of its driving range.
Not because anything is broken, but simply because the weather got cold. For someone living in Canada or Northern Europe, that can mean losing up to 100 kilometers of range on a freezing morning, exactly when they need it most.
These problems are not secrets.
Engineers have worked around them using better cooling systems and smarter software. But the underlying chemistry has never really changed. And the reason it has not changed takes us to a problem that has nothing to do with science. the fragile foundation of lithium supply chain. Three countries, Australia, Chile, and China, control as much as 90% of the world's mined lithium production.
China alone processes around 65% of that raw lithium into materials suitable for battery manufacturing and produces roughly 75% of all lithium ion batteries worldwide. That means most of the world's electric cars, phones, and energy storage systems depend on a supply chain that runs through only a small number of locations on the map.
Between 2020 and 2022, the price of key lithium materials rose eight-fold, not by 8%.
Eight times more expensive in just 2 years. Demand for electric vehicles exploded. Battery factories expanded faster than anyone expected. and the lithium supply simply could not keep up.
Then in 2023, the market violently swung in the opposite direction. Lithium prices crashed by more than 70% in a single year. Battery companies that had signed long-term contracts at peak prices suddenly found themselves paying far more than the current market price.
An entire industry was building multi-year business plans around a commodity that could swing wildly like a meme stock, completely outside the control of the companies relying on it.
For governments trying to build energy independence, and for automakers trying to make electric cars affordable for everyday buyers, this is a major strategic weakness. The world has built the foundation of its clean energy future on a raw material controlled by only a handful of countries with prices that can double or collapse because of forces the battery industry cannot control. And yet, despite all of that, for 30 years, the industry kept looking almost entirely at lithium. The reason goes back to a decision made in the 1970s, one that quietly shaped everything that came after it, the forgotten element. Go back to the 1960s before lithium was even on the map. And scientists were looking at a different element as the future of batteries, sodium. It sits right next to lithium on the periodic table, has very similar chemical properties, and is one of the most abundant elements on Earth. It is literally found in ordinary table salt.
The first rechargeable high energy battery ever built, created by Ford Motor Company in 1966, actually ran on sodium. But there was one fatal problem that almost killed the idea immediately. The battery needed to operate at around 300° C, hot enough to melt lead. Scientifically, it was a fascinating proof of concept, but it was not something you could put inside a handbag and carry around with you. Then in 1972, a researcher named Stanley Whittingham discovered a way to make lithium batteries work at room temperature. Suddenly lithium had an enormous advantage and nearly all research funding around the world started flowing in that direction. By 1991 Sony released the first commercial lithium battery and from that point on more than 1 trillion flowed into lithium technology.
Sodium was left behind not because it had been proven useless but because every major incentive and resource was now moving in the other direction.
Sodium also had one very specific engineering problem that nobody could solve. Sodium particles are about 35% larger than lithium particles. The carbon material lithium uses for storage, called graphite, is made of extremely neat and tightly packed layers, like a perfectly stacked deck of cards. Lithium particles fit neatly between those layers and can slide in and out thousands of times without causing damage. But sodium particles are simply too large.
Every time a sodium particle tries to force its way into graphite, it pushes the layers apart and permanently damages the structure. After only a few hundred charging cycles, the battery becomes so degraded that it is no longer useful.
That one materials problem pushed sodium out of the commercial race for more than 40 years until someone discovered a completely different form of carbon. And once that happened, everything started to change. The material that broke the curse. In 2000, a research team in Canada discovered a material called hard carbon. Regular graphite looks like a perfectly organized stack of cards with every layer parallel, evenly spaced, and neatly arranged. Sodium particles are too large to fit between those layers without damaging the structure over time. Hard carbon is completely different. It is made by heating organic materials such as plant waste, biomass, or even glucose to temperatures between 1,00 and,400° C in a sealed environment with absolutely no oxygen. The carbon atoms become locked in place in a permanently chaotic structure filled with irregular gaps and tiny pores. Those empty spaces are just large enough and just varied enough to comfortably hold sodium particles without breaking apart over time. For the first time, sodium had a material that could survive thousands of charging cycles without falling apart.
But discovering a breakthrough and turning it into a commercial product are two very different things. Hard carbon behaves like a sponge.
Its porous structure easily absorbs moisture from the air and even a tiny amount of water getting inside a battery can react with the liquid electrolyte, create gas, and slowly destroy the battery cell from the inside. This is where CL, the world's largest battery manufacturer, entered the picture. The company committed around $1.5 billion over 10 years to solve that problem. Its first breakthrough is changing the surface chemistry of the hard carbon itself, replacing materials that naturally attract moisture with compounds designed to repel water. Its second breakthrough was controlling the size of the internal pores during manufacturing with extraordinary precision down to the angstrom level which is 1/10enth of a billionth of a meter. If the pores are too small, sodium particles cannot enter efficiently. If the pores are too large, valuable storage space is wasted.
Finding the exact balance and doing it for a product manufactured at industrial scale took years of research that most companies were not willing to fund. The result of that journey is a battery called Naxtra. And the numbers it delivers would have sounded almost unbelievable for a sodium battery just a few years ago. What sodium can really do? Noxra reaches an energy density of 175 W hours per kilogram, putting it in the same performance category as lithium iron phosphate batteries, the type that powers many affordable electric vehicles today. In a real vehicle, that could mean more than 500 km of range on a full charge while reaching 80% charge in only 15 minutes. These are not laboratory figures. These are real production numbers from a battery that is already being manufactured at scale. The cycle life is what really stands out. Noxstra can handle more than 10,000 full charge and discharge cycles before experiencing major degradation.
That is roughly three times more than the lithium batteries it is competing against. If you charged it once every day, the battery could still be working well after 27 years of continuous use.
Then there is cold weather performance where sodium goes from impressive to genuinely extraordinary. The liquid electrolyte inside Naxtra can remain liquid at temperatures as low as -58° C.
At -40° C, the battery can still retain 90% of its full capacity. A lithium battery at that same temperature would barely function at all. For electric vehicles in northern climates, this could be the difference between a car that performs reliably all winter and one that loses a third of its range just because the temperature drops. And then comes the final deciding factor, cost.
CL is producing sodium ion battery cells at around $19 per kilowatt hour. Lithium ion batteries by comparison typically cost between $55 and $70 per kilowatt hour. That is not a small gap. And unlike lithium, both sodium and aluminum are abundant materials available around the world. Their supply chain is not concentrated in only a handful of countries, which means more stable and predictable pricing for anyone building products around this technology. So with better cold weather performance, longer battery life, much lower cost, and a more stable supply chain, does this mean lithium is finished? Two batteries, one smarter system. Sodium ion batteries do have one limit they may never completely overcome: energy density. Because sodium particles are heavier and larger than lithium particles, there will always be a ceiling on how much energy can be packed into the same amount of weight.
For electric aviation, where every extra gram directly affects range and payload, that limitation matters enormously. For consumer electronics, where the battery has to fit into a phone with almost no available space left, lithium will probably remain dominant for many years to come. What CL is building is not really a replacement story. It is a partnership between two battery chemistries with each one doing the job it is best suited for. The company has developed an electric vehicle battery pack divided into two separate storage zones, one using sodium and one using lithium. Software controls the system in real time, deciding which chemistry should provide power based on temperature, speed, and battery state of charge. Think of it like two athletes with different strengths playing on the same team. When the weather's cold and lithium is struggling, sodium carries more of the load. During a long highway drive that requires maximum range, lithium steps up and takes the lead.
Neither chemistry is pushed beyond its limits. Both are used at the exact moment when they perform best. That 60 gawat contract mentioned at the beginning of this video is the perfect piece of the puzzle for that vision. To understand the scale, CL shipped around 122 gawatt hours of total battery output for energy storage systems during all of 2025. This single sodium ion battery order represents roughly half of an entire year's output for a technology that had not even entered commercial production just 12 months earlier. There is a larger lesson here worth thinking about. Research proving that hard carbon could store sodium ions was published in 2000. This technology had been viable for large-scale storage for years, but serious investment in corporate attention only truly began moving towards sodium after 2022, almost perfectly matching the moment lithium prices surged. Lithium's weaknesses were never hidden. They had been clearly documented for decades. But when a dominant technology still works well enough and profits keep flowing, industries tend not to put much effort into finding something better. It takes a shock. A price collapse, a moment when the cost of not changing finally becomes greater than the comfort of staying the same. Sodium ion batteries did not suddenly appear out of nowhere. They spent more than 20 years sitting quietly in laboratories and research papers waiting for the world to become ready for them. That moment arrived because lithium itself forced it to arrive by becoming too expensive, too unstable, and too geographically concentrated for the industry to keep ignoring alternatives. Lithium is not going away.
It will remain essential in areas that demand maximum energy density, electric aviation, smartphones, ultra thin laptops, and anywhere every gram of weight matters. But sodium is opening an entirely new door for markets that need lower costs, longer life, better safety, and reliable performance in extreme weather. The real story behind the 60 gawat contract is not just a battery deal. It is a signal that a technology once considered a dead end is officially leaving the laboratory and entering mass production on a global scale. And it reminds us of a lesson much bigger than batteries. A technology that has been forgotten for decades is not necessarily dead. Sometimes it is simply waiting for the right moment to return. 30 years ago, lithium rewrote the definition of what a battery could do. Maybe sodium, the humble element sitting quietly inside every grain of table salt, is about to write the next chapter of that story. So, what do you think? Could sodium ion batteries truly replace lithium in the future, or will the two technologies continue side by side, each with its own role? Leave a comment below and let me know what you think.
