CATL Announces New Sodium Batteries coming out in 2026

This Sodium Battery Could Change Everything: Why CATL’s Latest Announcement Matters

For months, speculation has been swirling across the EV and energy world. Now, the wait is over. CATL — the world’s largest battery manufacturer — has officially revealed full details of its new sodium-ion battery, and while it isn’t the mythical “90% cheaper” miracle some headlines hinted at, it is a genuinely transformative development.

In fact, this chemistry could mark the beginning of the end for lithium iron phosphate (LFP) in its current form.

Clearing Up the Price Hype

Let’s start with cost — because that’s where most of the confusion has been.

CATL states that its new Naxtra sodium-ion cell currently costs around $19 per kWh at the cell level. For context, today’s large-scale LFP cells from manufacturers such as BYD, Tesla, and others typically sit in the $55–60 per kWh range.

That’s not a 90% reduction — but it is roughly 65% cheaper, which is extraordinary by any standard.

More importantly, CATL believes sodium-ion cell costs could fall even further, potentially reaching $10 per kWh within the next few years. Given this projection is coming from the world’s largest battery supplier — serving brands like Mercedes-Benz and BMW — it carries real weight.

And yet, price isn’t even the most important story here.

A Battery That Outlives the Car

The most eye-catching claim is longevity.

CATL says the Naxtra sodium-ion battery can deliver 3.6 to 6 million miles (nearly 6 million kilometres) before capacity drops to 85% of its original level. That’s three to six times the lifespan of today’s best LFP batteries.

In practical terms, this means:

  • The battery would outlast the vehicle itself
  • The same cells could be reused for second-life energy storage
  • Long-term degradation becomes far less of a concern

This fundamentally changes how we think about battery value, depreciation, and reuse.

Energy Density: Sodium Has Caught Up

Historically, sodium-ion batteries have struggled with energy density. Early versions typically sat in the 120–140 Wh/kg range, making them unsuitable for electric vehicles.

That’s no longer the case.

CATL’s new sodium-ion cells achieve 175 Wh/kg, which:

  • Exceeds BYD’s current Blade Battery (160–165 Wh/kg)
  • Enables real-world EV range
  • Makes sodium viable not just for stationary storage, but for cars

When you combine this with lower cost, improved safety, and dramatically longer lifespan, sodium suddenly becomes very hard to ignore.

Performance Where It Really Matters

Sodium-ion batteries also excel in areas where lithium often struggles:

  • Extreme cold performance: Operates normally from -40°C
  • High-temperature resilience: Up to 70°C
  • Cold-weather charging: Near-normal charging speeds even at -20°C
  • Material availability: Built from sodium, aluminium, carbon — all abundant and widely available

These characteristics make sodium-ion batteries particularly attractive for northern climates, commercial fleets, and infrastructure applications.

Not Just for Cars: A Renewable Energy Game-Changer

CATL has made it clear this chemistry is not just about EVs.

The company is targeting:

  • Home energy storage
  • Microgrids
  • Large-scale renewable energy projects

Why does this matter?

Because if a battery costs half as much and lasts three times longer, the entire economics of renewable energy shift. Solar is already the cheapest form of electricity generation globally. Pair it with low-cost, ultra-durable sodium-ion storage, and fossil fuels — and even nuclear — start to look increasingly uncompetitive.

The Hybrid Transition Strategy: Sodium + Lithium Together

One of the most intriguing details CATL revealed — almost quietly — is a hybrid battery system that combines sodium-ion and lithium-ion cells in the same pack. CATL calls this concept “Freevoy.”

The logic is simple:

  • Sodium handles the low-cost, long-life base load
  • Lithium delivers high energy density where needed

This approach allows manufacturers to:

  • Transition gradually
  • Reuse existing LFP production lines with only minor changes
  • Scale sodium-ion production far faster than expected

This is a smart, capital-efficient strategy — and one that could accelerate adoption dramatically.

When Will This Reach Consumers?

The headline $19 per kWh figure applies to the cell only. Once you add cooling systems, casing, electronics, and integration, full battery packs are likely to land around $40–45 per kWh.

That’s still far cheaper than anything currently available at scale.

CATL hasn’t confirmed when $10 per kWh cells will arrive, but two to three years appears realistic — especially given that sodium-ion cells can be produced on existing manufacturing lines.

The Bigger Picture: Energy Independence

Zooming out, this development goes well beyond electric vehicles.

If batteries can be:

  • Cheap
  • Safe
  • Long-lasting
  • Made from abundant, locally available materials

Then countries no longer need to depend on imported lithium or fossil fuels. Sodium-ion batteries can be produced almost anywhere, used locally, and operate for decades.

This could represent a pivotal moment — one we may later look back on as the point when lithium began to lose its dominance.

So, Is This the End of Lithium?

Probably not overnight.

Lithium — especially high-energy chemistries — will still have a role where maximum energy density is required. But sodium-ion batteries are clearly poised to take over huge parts of the market, particularly where cost, durability, safety, and sustainability matter most.

Lithium and sodium are likely to coexist — but the balance of power is starting to shift.

Final Thought

This isn’t just another battery announcement. It’s a structural change in how energy storage might work over the next decade — for vehicles, grids, and entire economies.

What do you think?
Is sodium-ion the successor to lithium, or will they live side by side long-term?
