Yes, but that is Lithium-ion. These batteries are Sodium-ion which are better for the environment and can potentially be made a lot cheaper.. It's still pretty new technology so it's not really in any consumer products yet.
Sodium batteries are already in electric cars many months ago

Also you could buy individual cells on AliExpress

Sodium batteries will not replace lithium in cars, as the density is too low.
It means the battery weighs more but contains less power.
For an EV, that wouldn't work, as the heavier the car is, the more power it uses.
With sodium you will probably half the range of the EV, which is already low.
For medium distance commuter cars and inner city travel those things dont matter and will probably be outweighed by the cost savings, safety and reliability of sodium batteries. The main issue right now with getting EVs into more peoples hands is cost.
