Redox flow, sodium ion, iron air, etc.
There are some 600+ current chemical-based battery technologies out there.
Hell for me, once sodium is cracked, that shit is so abundant that production wouldnβt have many bottlenecks to get started.
Will Li-ion battery companies let that happen? They want profit, which means they want to keep the high battery cost.
Oil & Gas companies didnβt want Solar, Wind, and Storage to proliferate, yet they did because of cost savings.
I think we could start to see that for these alternative-ion batteries if lithium supply ever becomes an issue. There will always be a niche that has the opportunity to grow in the economy. Just takes the right circumstances and preparation
