- size and weight per WH
- cost
- operating AND charging temperatures
- cycle life (# of charge/discharge cycles)
- how "safe" the chemistry is

LMFP and sodium-ion based batteries look more promising in the near future to drive EVs prices down

Also. Solid state batteries has also wider range of usability when it comes to temperature. Current batteries has very thin range, can't go too warm and can't go too cold. So they are bad both when it's winter and summer. Cus either they overheat or you need to use energy to warm them up to make them work as they should, cuz cold batteries can't out put full valtage they are designed to.

Well. That's main goal. To have more capacity per KG. That way you can pack the same battery and has lighter car that can, thanks to reduction of mass, also drive longer distance than the same card with the same battery capacity that is older and heavier.

The phones also can use smaller batteries with the same capacity to lower mass or thickness.

How is it being calculated "that the cost is the same as conventional batteries"? If the cost per Kwh is the same, it means that there is no advance beyond the reduction in weight and space occupied.
