Batteries

While reading that, I started thinking about how that energy density compares with other chemistries. I found another article, which clearly illustrates how much variation there can be. You can find a very good LFP battery and a bad NMC battery, and their energy density could be identical.

When I think of energy densities, I usually expect LFP to have about 100 Wh/kg, and NMC should be around 200 Wh/kg. If these SIBs can deliver about 145 Wh/kg, they would be somewhere in between the two.

The way I see it, SIBs might not be a popular option for cars, unless the NMC prices go through the roof. Battery anxiety is a very real thing, and even with NMC/NCA, you are painfully aware of it all the time.

I don't think that SIBs are going to solve that problem just yet, but they might solve a bunch of other problems. For example bikes, scooters, power tools, flashlights or even grid energy storage could be suitable applications. Before we get there, these companies would need to ramp up production, but it's looking surprisingly good so far.
