Interesting, but I have to wonder what the operating temperature is and what happens when it freezes.
I found another article on it that talks about it having a better use as charging station buffer storage since it’s hard to provide enough current to a site with lots of EVs charging at once at very high currents.
Since we’re unveiling the Gamma version of Aptera in a day or two at the Fully Charged show, here is a link to another innovative battery type that claims a weight/performance equivalence with LFP chemistry – i.e. not as energy dense as the batteries Aptera is using.
The battery is salt-based, is in production in the UK, and promises to be a fraction of the cost of lithium-based batteries. The video suggests a potential cost as low as $10 a kwh although I do recall a more realistic $70-80 per kwh cost (I need to watch it again). One of the presumed problems with the tech is that while they can be recycled like lithium batteries, the value of the chemical’s being used are so plentiful that it may not be economically feasible. Fortunately, these chemicals (primarily salt) are relatively benign and don’t pose an environmental danger.
Because of the abundance of materials local sourcing is really easy.
The problem is that with weight being the issue with Aptera, the mass of a 25kw (250 mile) Aptera equipped with this battery would probably only muster 20-22 kw’s of storage. Aptera could simply split the difference in mass between the 250 and 400 mile versions and use this ‘cheap’ type battery for its price leader if that would qualify Aptera for the $7500 federal credit if battery sourcing was the only impediment.
Oh, and according to Fully charged, these salt-batteries are currently in production.
