*** [[Sodium-ion batteries]] are made from abundant materials - they don't have any mineral-scarcity problem ([[Do we know for sure that sodium-ion batteries avoid mineral scarcity?|probably]]). But they hold even less of a charge than LFP. | *** [[Sodium-ion batteries]] are made from abundant materials - they don't have any mineral-scarcity problem ([[Do we know for sure that sodium-ion batteries avoid mineral scarcity?|probably]]).

**** Sodium-ion batteries are [[status quo of sodium-ion batteries|quite new to the market]] (in 2024), and the hope is that they'll become a lot cheaper than existing batteries. That way, [[short-range EVs|EVs could be cheap and durable]], with the only tradeoff being the lack of range.{{qn}} Probably still good enough for city/suburban living. | **** Sodium-ion batteries are [[status quo of sodium-ion batteries|quite new to the market]] (in 2024), and the hope is that they'll become a lot cheaper than existing batteries.

*** For '''buses''': LFP and sodium-ion are both perfectly fine. The {{p2|lower ''energy-per-weight''|i.e. the fact that more battery mass is needed to hold the same amount of electricity}} is not a problem, because buses need extra weight at the bottom anyway for stability. | *** For '''city buses''': LFP and sodium-ion are both perfectly fine.

If sodium-ion batteries are on the market now, how does their cost compare to lithium-based batteries so far?}} | * [[Next steps for sodium-ion batteries]] {{talk|Is it true that sodium-ion EVs are available in China already, and just not in North America?
