these seem like they’d be great for a UPS, or even home battery and wind/solar
This is the first “big 2” companies doing Sodium Ion. There have been others. This is biggest plant. It is still early days for production. Mass availability will come later.
What form factor are they manufacturing these in? I’d love some way to swap in a battery for an electric conversion for an old BMW 2002
It’s not the best battery type for cars, unless perhaps you are near arctic circle. They are heavy.
Sodium-ion’s main advantages are safety, and ultra abundant material source for unlimited batteries, if lithium becomes expensive.
I thought sodium had high charge cycles, as well.
it does. LFP can cycle (slowly) 1 per day for 30 years though. 10 years at full fast charge/discharge. Because of financing/opportunity cost of money, the longer cycle life of Sodium Ion is not a game changer.
Fair points.
Thanks for the considerations. I’ll do more research
LFP batteries have huge supply capacity, and have very high value. Amazon, or other sources, are appropriate for a personal project at low cost.
If you have the time or inclination can you tell me if I should wait for solid state batteries or just use the mature LFP. I’m fully aware of the impending tariffs and am already factoring thay into my budget.
LFP batteries are better for EVs/mobillity (with NMC better for ebikes/perfrormance). In some parts of the world, LFP may become more expensive due to extra tariffs, while other parts it can become even cheaper due to high production capacity, and tariffs elsewhere. In the next 1-2 years, LFP is likely cheapest and best option. In 5 years, maybe sodium ion is super cheap.
