I continue to read around on Battery storage solutions, both domestic and grid scale, and often the public criticisms are about battery health, material availability and safety.

Cobalt-type cells (NMC etc) seems to be the default solution for vehicles thanks to their energy density, but in country you do also see Lithium Iron Phosphate (LFP) amongst the numerous EVs available on the Chinese market.

Not containing cobalt, far better failure performance and better longevity at high rates of charge sounds ideal for a battery that is used in static devices, closely packed and potentially in homes.

So why isn't LFP used in these applications?

Is it just a scaling issue? Does anyone have a knowledge of market prices comparing different cell types?

I think Sonnen use LFP. There's a company going to be sending me a quote and more detailed information about it.

All our home batteries use LFP.
