I want to replace my Lithium home battery, and what I really want to do it to move to one of the new sodium ion batteries..e.g like the one CATL is supposed to have at some point?
Anyone have a good idea when these will be available for consumers?
- XorNot 2mo agoWhy would you replace it? That asset likely has at least 10 years in it if you already have it.
- syntaxing 2mo agoProbably operating temperature and safety.
- rapsey 2mo agoWhy? You also need to replace your inverter in that case.

- xbmcuser 2mo agoWhat bullshit are you spouting sodium batteries are safer and do not have the same thermal runway concern that lithium batteries do.
- rcxdude 2mo agoWhat? All the data suggests that sodium ion batteries are safer than lithium ion batteries: it is harder to set them into thermal runaway and they are less violent when they do so.
- chewbacha 2mo agoPretty that’s just not true. Sodium ion batteries are less energy dense than lithium ion and are not prone to dendrite formation. They are also more thermally stable and less likely to do thermal run away reactions. Also, since they are less energy dense they don’t store the same potential energy. You are probably thinking of metallic sodium batteries which are completely different.
- Aboutplants 2mo agoYou have this flipped backwards
- bearfood 2mo agoYou must work for a LiPo company. This is the opposite of truth. Sodium doesn't behave like lithium at all. The chemistry is very different. Imagine if table salt had an exo reaction in water
- icehawk 2mo ago> This is bad in that when the battery malfunctions, the energy is released at 30x the rate Got a study you can link about that?
- cyberax 2mo agoNa-Ion batteries are not practical for home storage right now. They have a much higher voltage range compared to LFP batteries, so regular inverters and chargers will not work reliably. Nothing insurmountable, but the supply chain is just not here. Na-Ion cells are great for grid-scale storage because they potentially can go down to something like $20 per kWh. But bulk LFP cells are already at ~$60 per kWh, so their cost is not really a deciding factor anymore.
- syntaxing 2mo agoBluetti has a small battery pack for now. I think the options for consumers will balloon once CATL mass produce sodium ion cells. Solix/anker, jackery, ecoflow, etc all use CATL cells already.
- cbg0 2mo agoProbably in a year or so. CATL is expecting about 1GWh deployment by the end of the year and has contracts to deliver ~7GWh in Europe next year, so they're clearly ramping up production towards the end of this year.
