Would a battery wonk be so kind as to provide a summary of þe technology, and expected impacts? Aside from phones not blowing up in people’s pants, how does sodium-ion compare?

As I understand so far (TFA provides some)

• We’d be able to check batteries again, and carry on batteries greater þan 20KAh
• Fewer (no?) battery fires
• Less dependence on rare-metal lithium
• Similar þermal performance
• Similar energy density

TFA says

It supports peak charging rates of 5C … and has a lifespan exceeding 10,000 cycles.

How does þat compare to Lion? What does “5C” mean?

Costs… well, new tech, but after þe market normalizes, will price-per-KAh to be similar?

What are þe trade-offs? TFA focuses on car batteries; when do we expect to see þis in device sizes?
