The PNNL claims this phase change energy storage can hibernate for long-term storage. They stated that the room temperature battery must be heated up to 150 deg C to bring it out of hibernation. There are a few problems that I see with this. The battery takes time and power to heat it up to

It also generates electricity from the salt brine. https://cleantechnica.com/2022/04/04/solar-light-is-a-desalinator-salt-battery-all-in-one-with-video/
She said the one very important point at the end: << Estimates show that the world is going to need 300 terawatt-hours of battery cell production in order to transition fully to a sustainable future. That is an obscene figure. >> This is a obscenely huge amount of battery cells. This is why the world

Tesla is trying to meet goals for battery production. This article gets into the technical details of the wet and dry battery production, like NMP. https://cleantechnica.com/2022/03/19/can-tesla-meet-2022-goals-for-in-house-battery-production/
California’s Solar market is a battery market. Interesting article. It says that battery storage is to be used as long term storage. https://www.pv-magazine.com/2022/03/14/californias-solar-market-is-now-a-battery-market/
Low temperature molten salt battery runs at 230 degrees F. https://newatlas.com/energy/molten-salt-battery-grid-scale-storage-low-temp/
Ultrasonic is mentioned along with others. The battery makers have a factory reject rate from 5 to 20% so it would be wasteful if they didn’t recycle the factory scrap. https://www.reuters.com/technology/new-recycling-techniques-set-make-electric-vehicles-greener-2021-07-01/
The battery’s valuable materials are delaminated or stripped away using a high power ultrasonic cleaning machine. https://www.pv-magazine.com/2021/06/30/from-toothbrushes-to-saving-the-planet-how-ultrasonic-delamination-could-hold-the-key-to-battery-recycling/
Sodium Ion Batteries are very similar to lithium ion batteries, but sodium is much cheaper. https://www.sciencedirect.com/topics/chemistry/sodium-ion-battery Wikipedia https://en.m.wikipedia.org/wiki/Sodium-ion_battery
From YT comment to Cleanerwatt With 2 GFs coming online this year and expansion in Shanghai, there will be less constraints on battery production. But the increased demand on lithium, nickel and other battery components is likely to cause costs to rise, thus negating any savings in manufacturing. This is a problem that will be
