Exciting to see all sorts of batteries for different applications. Is lithium-ion still standard for home power backup? I’ve heard characteristics of the new sodium-ion batteries being ideal for that use case.
It really is exciting to see alternative battery systems beginning to see wider commercialization.
I am not aware of sodium-ion batteries for home use, I believe it’s mostly for industrial-scale battery systems. I could be wrong though, would be interested in learning more.
In an apartment setting, IMO the current gold standard is LiFePO4 (Lithium iron phosphate) batteries.
I live in Ukraine and we have constant problems with electricity supply (thank you dear russians). At times you have 1-2 full charge/discharge cycles per day on a 1 Kilowatt-hour battery system. Several LiFePO4 systems in my extended family seem to work close to baseline even after 1.5 years (not used daily though).
I have not seen any options for sodium-ion batteries for home use, but this maybe a local thing.
In a more rural/suburban setting, generators work as backup power supplies for most people. Typically only the well off get a high capacity LiFePO4 systems for house setting.
Sodium ion batteries are really just hitting the mainstream. Prior to now, they appear to have been more from pilot projects/factories, but a couple large factories are being built now. I expect they will be very popular for stationary use in a couple years.
I wish there were more Nickel Iron (Edison) home battery options. Those run for over 100 years and are perfect for a home where size/weight don’t matter.
It’s very uncommon for them to last 100 years, but they do last a lot longer than any lithium or lead acid batteries. The charging efficiency is rather low, which is probably why you don’t see them used much.
