Even thought I'd agree mass EV would not be carried by the current grid, or that charging density and time is not satisfactory (in most of Europe)... LiFePO4 doesn't contain rare earth metals, unless you count Li for 'rare'.
Also probably unaware that with the rise of extremely low cost, solar and wind, Fossil fuel use on the grid is economically nonviable long term.
Even so, the fossil fuels consumed on the grid are very likely to be combined cycle natural gas, which has less carbon emissions than have equivalent. Amounts of energy were burned in ice engines.
Also, The energy efficiency of electric vehicles is much higher than an ice car, so if solar and wind do not generate the electricity, it still will emit less carbon than an ice.
The only useful new engine technology I am interested in is an extremely compact recharging engine for use in plug-in hybrid electric vehicles. There was something about the inside out rotary engine a couple years ago but nothing has come off of it.
I'd not call the rise, yet. The Na ones' energy density (and specific energy) is even lower than Li based (LiFePO4 is lower than cobalt ones). They might be okay for grid storage, of course.
So the pack level they become a lot more competitive. Rise of high density, salt, water and lfp. We should be able to produce 300 and 400 mile range sedans with sodium ion and LFP chemistries.
Just go look at the catl density numbers all the stuff they have going into production. Obviously has not scaled to the level it needs to. That's a big ramp up.
I believe the current numbers are 160 Watt hours per kilogram for sodium ion and a little over 200 for lfp. With cell to pack projections of 90%, while pack density of nmc is like 60-70% to the cooling and safety system requirements, sodium ion is a revolutionary development for the cheap EV.
The five year road maps for sodium ion gets it close to 200 watt hours per kilogram. Lfp should be reaching 250 Watt hours per kilogram in the next five years.

Tuning SIB chemistry and getting enough factory capacity up takes a while.
In many places putting solar panels on roofs and on parking spaces would solve such issue.
No need for personal snark comments. Not everybody lives in the US. The worst part moving there was surviving the lack of sun light during the winter but that was many years back.
