Two years ago, sodium-ion battery pioneer Natron Energy was busy preparing its specially formulated sodium batteries for mass production. The company slipped a little past its 2023 kickoff plans, but it didn't fall too far behind as far as mass battery production goes. It officially commenced…
Yeah but for many low-power applications, it's a damn cool development. Like I have a bluetooth keyboard and a few controllers that could eaisly fit a battery 3x-4x the current size inside no problem, so there's no need to waste lithium on that.
Potentially cheaper and uses more abundant materials than lithium ion, but not as energy dense, so not ready yet for automotive purposes. They have a much higher cycle life and faster charge/discharge rates, though, so good potential for applications that don’t need to move like data center power backups.
My first goto would be a cellphone battery. Having a cellphone battery lasting months longer than what I had to deal with on my old phone. I welcome this.
From my limited understanding of the technology, sodium is more common and easier to obtain than lithium, and is less damaging to the environment to mine.
May not pack the same energy density though, but it's a tech still in the works..
There's not enough known lithium deposits in the world to make the batteries needed to decarbonize transportation and provide the energy storage needed for a fully renewable grid. That is not true of sodium, which is cheap and abundant.
At the current energy density, they're more suitable for stationary storage. But we need a lot of that, so that's a win. Sodium is cheap and abundant, so those cells should be a lot cheaper to produce.
