Solid State Batteries

According to Designfax, Nissan will be making solid state batteries with double the energy density and lower cost by 2028.

Yeah, everyone is making that promise but there's little evidence so far that solid state batteries can be scaled for use as EV packs at a reasonable cost (ie $75 per kWh as mentioned in that article). Hopefully they pull it off, but there's plenty of reasons to be skeptical...

What I've heard is that the tech is 'one miracle' away. That could happen anytime or maybe never.

It always amazes me how the business folks just extrapolate progress and assume that all problems can be solved in a timely manner. Unfortunately, physics isn't always like that. Eg fusion power. It's been 10 years out for the last 40 years.

I agree that battery tech is moving so fast that the advantages of solid state could mute by the time they are in production.

Might know fairly soon.

Isn't that 30 years away?

Fusion has been making steady progress as measured by Lawson criterion. However, once a reliable, many months at a time fusion burn has been achieved, still need to extract that energy as electric power.

To an extent, we can with increased funding speed the process up. Easy in the 1950's as early experiments were cheap. Gets expensive at ITER scale. Building the first power generation plant is going to be even more expensive. How long is not just technical issues.

Interesting, thanks for sharing!
