The NMC line is larger than the LFP line.”

This brings up (a) point that may ultimately be (the) point. Wet chemistries compared to dry battery cell chemistries like solid-state. Wet cells have one or more “drying stations” along the entire assembly line that needs specific engineering to keep volatile compounds from “pooling” in the manufacturing area and creating an explosive atmosphere. Solid-state battery chemistries usually don’t need the drying stations saving space, steps, energy and time to make each cell. The more cells per minute, hour, day of a manufacturing line, the cheaper they can be made. Getting battery packs down to $50/kWh would change the way people use energy storage in their daily lives. Bring it on!!!

If there is a way to get a silicon based nanowire anode material into the LFP battery chemistry this should improve the fast charge capability of the LFP chemistry. Companies like Innolith says they have an (Inorganic electrolyte) that is much less volatile than the current organic electrolytes used now in batteries. With engineered graphene cathodes one might find a chemistry for LFP that would double the gravimetric energy density of the LFP chemistry. That would put the LFP ahead of the NMC chemistry as a battery chemistry choice in the near future. For instance Australian company GMG is working on an aluminum graphene battery chemistry that has a “theoretical” gravimetric energy density of around 1,000Wh/kg and possible full charge/discharge cycling of around 3,000 cycles. 70% faster charge rate than standard LFP and much less temperature effect on the battery chemistry. Allowing one to use 90% cells in a battery pack by weight, increases the overall range of any BEV using the chemistry.
