Sodium-ion batteries have been in development since 1970s and the lithium-ion batteries have been in development since 1960s. Not much of a difference.
It’s not just the amount of time. The portable electronics market and the electric car market both settled on lithium batteries, which created a huge demand for that particular technology. Over the past 2 decades there has been a massive incentive to develop smaller, denser lithium batteries.
There may be interest in developing other battery technologies, but nothing like the amount of money and effort being spent on lithium batteries.
And before that there were several decades of massive incentive to develop smaller more powerful ICE engines.
Lithium probably has some room to grow, but it also has a lot of problems like volatility and materials sourcing. EV manufacturers have been searching for ways to make better/cheaper/denser batteries, not better/cheaper/denser lithium batteries. They’ve been actively searching for alternatives.
