    interesting, 4 times the power as lithium but only lasts 1000? cycles,,, but if the price is right... and it does look to be less expensive than current lithium batteries....   especially if it may not require BMS...

    it uses glass electrolyte...https://www.engadget.com/2017/03/05/goodenough-solid-battery-technology/

    At 94 years old, John B. Goodenough isn't done changing the landscape of battery technology. The University of Texas at Austin professor who's widely credited for the invention of lithium-ion batteries has developed a better alternative. Goodenough, Cockrell School senior research fellow Maria Helena Braga and their team have created a low-cost solid state battery that's safer than lithium-ion. It stores thrice as much energy, which means more miles for electric vehicles in between charges. When you do need to charge, it can be done minutes instead of hours. Plus, it can withstand a greater number of charge and discharge cycles.

    The team's technology uses glass electrolytes instead of liquid like lithium-ion does. By using solid glass, the new battery won't form dendrites -- whisker-like pieces of lithium that usually form in liquid electrolytes. They're the reason lithium-ion batteries have the tendency to short circuit and explode or start a fire.

    The glass electrolytes also make it possible for the battery to operate in subzero degree (up to around -20 degrees Celsius or -4 degrees Fahrenheit) weather. And since their use means the creators replaced lithium with low-cost sodium, the batteries can be manufactured with earth-friendly materials. Someday, the new technology could make EVs more common and change the way we use our gadgets.

    ADD: ''Emphasis added''

    For now, Goodenough and his team are looking to pair up with battery makers who can test their creation in electric vehicles and energy storage devices.

    As soon as I see field proven product........

    I always have more questions than answers. That's the nature of life.

    Solid electrolytes have a few problems.

    1) Dimensional stability.  Many of them shrink and expand during charge cycles; this results in cracking and eventual wearout.

    2) Charge carrier mobility.  Not surprisingly, ions do not move as quickly through solids and thus conductivity is much lower.  That means they work OK at C/100 (smoke detectors, IoT devices, real time clocks etc) but not so well at the C/10 or C/2 rates you need for homes or EV's.

    If they solve those issues, great; you could use solid lithium anodes and get significantly more energy storage.  But that's a ways off.

    And one that is for sale at our suppliers or the store here at wind & sun. He is a cool old guy :)

    Looks like several auto makers are promising solid state battery powered cars by 2025.       They must find the technology promising.

    Sure, it's promising.  So are flow batteries, salt batteries, zinc-air batteries, graphene batteries, sodium ion batteries, "microsupercapacitors" and the like.  But until they start mass producing them - best pin your plans on existing chemistries and constructions.
