It's a long way off a product at this point. They have done little more
than prove the idea works. The scale up and production challenges are at
least as difficult and where many good ideas disappear when it's found
not practical to manufacture in large volume.

Now that some one's worked out how to do it with a sulphur-lithium,
other pairs of reactive metals that were too reactive to be put together
might be tried.
But I don't think any of the solid electrolyte chemistry's will ever be
high current devices, either on discharge and more importantly recharge,
but who knows what those materials science boffins will mix up.

But it's in the realms of basic materials science research at the
moment, it's not product research.
