Western Australian battery technology company Altech Batteries has announced its first Cerenergy ABS60 salt-based battery energy storage system prototype is online and operating successfully across a range of temperatures, confirming its thermal stability and commercial viability.
its why their main benefit is cost and safety. for power storage in a standing field or wall density isnt as important compared to for mobile usages (EVs) so sodium based batteries make more sense.
There’s still room in car design for bigger batteries too. Could be used in cheaper electric cars with a less optimal power to weight ratio than LiFePO batteries would yield.
not saying they wont be used of course, just less optimal because the size and characteristics of the battery may be less ideal. for example, while salt ion batteries wear level decreases at a slower rate than Lithium ion based batteries, when salt ion batteries go bad, they suddenly stop working (e.g goes from a wear level of say like 60% to almost immediately zero) which is not the ideal situation to be in
I see a future where an EV will have two batteries each with different chemistries. An example would be to have LFP for the “main” battery which can take a beating but is less dense, and an additional NMC battery which gets used far less frequently, but is available for the less frequent long distance needs. This could also mean that when the LFP is dead from use, it can be replaced independent of the NMC which will have had a fraction of the charge/discharge cycles.
