With serious progress being made in solid state batteries, what areas do readers think they will have the greatest impact on the semi sector?
Phones will last for several days on a single charge. Charging will happen in a few minutes. Batteries will last the life of the product with little to no degradation.
I think that this will likely have a negative overall impact on the progress of low power semiconductors as it won't be likely as needed to achieve design goals .... and sometimes you can reach "good enough" without doing better power management with the silicon.
Battery technology will likely continue to increase exponentially over the next 5 years, but will see steady increases for the next decade. The demand for this technology in EV's and home energy management (as well as green power initiatives), will drive the technology with funding from everywhere.
Our grandkids are going to think it is funny that you used to have to drive your car somewhere to fuel it up, and that you fueled it with something that was very explosive .... and everyone thought that was OK

.I personally don’t believe solid state batteries will have a major impact. The reason is that conventional batteries are still improving at a rapid rate and there is long runway for continued cost reductions and performance improvements for conventional battery technology.
Solid state is not offering that much performance improvement, but the cost is very high. By the time cost of solid state drops, conventional battery performance will have improved to the point where it’ll be irrelevant, except in a few niche applications.

It's really a matter of space, weight and money. Yes, current technology batteries are improving and getting less expensive every year. Still, the step jump in metrics to solid state offers batteries on an entirely new level, much like the step jump from NiMH to Lithium did.
I believe that battery technology is still in its infancy, and that we are going to witness exponential improvement over the next decade. Solid state will definitely be part of that.
Imagine having solar panels on your home (or in your yard) or a wind generator and having enough battery capacity that you NEVER pay a dime to a power company for energy and you NEVER pay an oil company for fuel. I kinda like that future myself

It looks like the combination of battery improvements combined with advancing solar and small efficient windmills that will be ducted and shrouded combined will be real game changers. Imaging a house or building roof designed to funnel wind to a shrouded/ducted wind generator set for efficiency. Even the roof could evolve from a fixed structure to an active one.
The only real difference between a solid state battery and a non solid state battery is solid electrolyte. Everything else is already solid.It's really a matter of space, weight and money.

So the question is what about solid electrolyte allows solid state batteries to have higher density? And the answer is that although there can be some performance advantages for solid electrolyte, that's not the reason for the density advantages of solid state batteries. The advantage is that solid electrolytes are generally compatible with lithium metal anode and most liquid electrolytes are not. But research is happening on liquid electrolytes and it seems like there is some progress in finding liquid electrolytes that are compatible with lithium metal anode - and the cost advantage of liquid electrolyte is pretty significant.
There is a lot of materials innovation happening in the battery space, and I expect that to continue, but solid state is overhyped in my opinion.
I don't have an opinion on these battery technology in particular but overall the advances in battery production that drive costs down and allows us to increasingly build at scale are important for whole economies. It will also finally allow us to transition to green energy alternatives instead of using gas and coal.
