Yes, anything with the same chemistry is also dangerous. I would hope Powerwalls would have better cell isolation as they aren't as constrained by weight and size as in a vehicle.
That said, it looks like Tesla is going with LiFePo for powerwalls which is a much safer chemistry.
- fy20 5y agoSupposedly Tesla uses NCA for its cars and NMC for Powerwalls. Most other electric car manufacturers use NMC. However the properties of a battery vary greatly depending on the structure of the cell, and even more so on the cooling of the battery, so you should not compare them on chemistry alone. The reason why LiFePo4 (LFP) is safer is because it doesn't exhibit thermal runaway and is less energy dense. https://www.powertechsystems.eu/home/tech-corner/safety-of-lithium-ion-batteries/ https://www.powertechsystems.eu/home/tech-corner/safety-of-l...
