Comment Are we still doing lithium? (Score 1) 45
If we look past the maximalist approach to squeeze every last kWh/kg, sodium batteries are already there. They're even selling sodium starter batteries, going beyond their use in cars. Better low temp performance, comparable capacity, and having the stellar distinction of not being rolling bombs. Why are we still so focused on the rare earths and patents needed for lithium ion? The logic of "lithium batteries have been in development for a fraction of the time ICE have been, so give it a little more time and they'll be comparable to ICE" should now be applied to sodium ion batteries.
