The massive amount of production-oriented research in solid state and semi solid state batteries indicates to me that this stuff is coming soon in a big way. I've been curious about buying an electric car recently, and if I buy one right now it would only be a used one, don't want to fully invest in something about to be obselete.
The whole industry is always working on improved batteries. But it's a long road from lab-scale to mass production, and often improvements in one area have downsides in another.
New generations of cells that improve energy density usually start out more expensive than existing chemistries, so they show up at the high end of the market first and work their way down.
If we do get truly improved solid-state batteries available in EVs in the next 5 years, it will likely start at the high end of the market and work its way down over many years to cheaper segments as production capacity ramps up. The base model EVs aren't going to suddenly have their batteries swapped out with ones that are twice as good for the same price.
I make the same argument when I buy a computer. If I just wait a little longer, there will be a faster cheaper version of what I can buy today. When buying anything that depreciates, the best strategy is to wait (possibly forever) and only buy when you really need it now.
I hope you are right, but maybe this one is not like the previous ones. Micron leaving consumer market sounds like the real money will be on the AI hardware market.
Personally I bought my new laptop a month ago. Let's hope when I have to buy the next one this craziness will be history.
