A new EV battery being released is always pretty exciting news within the automotive world.
The advent of electric vehicles on a mass scale has seen several different companies push the envelope.
Now, a new EV battery has been released that is made from salt.
And what is even more exciting than that is the fact that it could last for 3,600,000 miles.

New EV battery could completely change the car world
This new EV battery is a creation that could completely change the game for electric cars.
In case you’re wondering – it isn’t from some unknown start-up chancing its arm.
As a matter of fact, it’s been created and produced by the world’s largest EV battery brand.
CATL is the manufacturer at hand, and it has just announced an all-new chemistry.
This new battery costs 10 percent of what current lithium-ion units cost.
It may also deteriorate so slowly that it will keep 85 percent of its charging capacity after driving 3.6 million miles.
Those two sentences alone are headline-grabbing as they are, but they’re not the headline here.
The headline here, in fact, is what this new EV battery is made of – salt.
CATL’s new ‘Naxtra’ range of batteries is what could prove to be the difference.
The combination of sodium-ion and lithium-ion cells balances the two chemistries.
It works in more extreme temperatures, and experts predict it will last for many more charge cycles.
So, what is the reasoning behind the revolution?
CATL Naxtra battery could last forever
Well, there are actually quite a few reasons why this could prove to be the difference.
The single biggest difference is, in the eyes of many, the most important one – the price.
After decades of improving mining and refinement infrastructure, the price of lithium-ion batteries is finally down to $100/kWh.
This means that a 70kWh Tesla Model 3 battery is $7,000 of the total car’s cost.
The Naxtra version, on the other hand, costs just $10/kWh.
Using the Tesla Model 3 example, a Naxtra power source would cost $700 for the same car.
Another revolutionary factor in the CATL range is its longevity.
Because sodium-ion batteries are more stable than lithium-ion batteries, Naxtra batteries may deliver 10,000 cycles before degrading.
Theoretically speaking, Naxtra batteries could last 3,600,000 miles before reaching 85 percent capacity.
Could a CATL Naxtra new EV battery convince you to switch to an electric vehicle?
