Liquid Metal Battery

Don Sadoway | Innovation in Stationary Electricity Storage: The Liquid Metal Battery
This video is a little long (nearly an hour), but he covers a wide range of issues pertaining to batteries. The bit about Volta (32:20) was fascinating. The general idea, as I understand it, is to build large batteries that can be charged when consumer demand for electricity is low, but your solar and wind power systems are producing. Elon Musk / Tesla are doing this successfully with Lithium-Ion batteries in Australia.


This video is a couple of years old. Mr. Sadoway's company, Ambri, had a couple of problems but they are still going strong.

Wikipedia has an article about Molten Salt Batteries which includes a section on Liquid Metal Batteries.
