I discussed this article with Mooch a few days ago, I found it interesting, but according to Mooch nothing beats liquid electrolytes, I’m just quoting what he told me (rather than interpreting).

That’s what he said to me:

Mooch said: “Hopefully in a few years he will be able to commercialize his work…a very long way to go though as solid-electrolyte cells have been in development for a long time. I am hopeful though because it addresses a couple of failure modes.

But I’m thinking they will only be very low current rated cells. Ion mobility through glass is much worse than through a salted liquid.”

Me: And it is true that objectively solid electrolytes by experiment are poor performers in terms of pure current.

Can a single flapping of a butterfly's wings trigger a tornado at the other end of the world?

Please give a synopsis for those of us who won’t give up our ad blocker for an unknown website?

Goodenough along with senior research fellow Maria Helena Braga, lead a team of researchers who have developed a low-cost all-solid-state battery that is safer and more efficient than existing lithium-ion technology.

The new battery uses a sodium- or lithium-coated glass electrolyte that has triple the storage capacity of a lithium ion battery. It also charges in minutes instead of hours and operates in both frigid and hot weather (from -20 to 60 degrees centigrade). Early tests suggest the battery is capable of at least 1,200 charge-discharge cycles, significantly more charging cycles than a comparable lithium-ion battery, and best of all, the glass-based electrolyte will not form the dendrites that plague lithium-ion battery technology. The dendrites accumulate as part of the standard charging and recharging cycle and eventually cause a short circuit that often results in a smoldering or burning battery.

Ah yes, another “new battery breakthrough!!! 5x capacity!! 10 minute charge!111!” article that will never happen.

This guy has good news about solid-state batteries. Still, 10 years until this tech will reach consumers at an affordable price.

it may be ok for home use where space and weight and even cost do not matter that much

Yes, as the cost of solar and wind comes down, we will also need storage solutions (or solids Big Smile ), so that we can cope with increased demand at certain times of the day, or even during a week of low wind and sun.

There are so many chemistries currently being pursued that we will have something good in ten years, maybe sooner.
