An expert in ceramic separator materials as well as a former R&D employee both indicated that had QS kept the temperature at 30C like their other tests, they would not have been able to show this favorable result.",

As you can guess, there are some benefits to going higher in the temperature. The battery performs more favorably.

So, by that temperature, you're a pretty high fraction of the melting point. If you're at the melting point, you can't make a dendrite. You also can use NMC as a cathode material, so you can't really run at 180°C. If they chose 30°C, like the other slides, it would be harder to achieve this result.” – Solid-state expert",
