I think that I read about these a few years ago. The one I saw was developed by a collaboration with Stanford University and someone else. I'm surprised that it has become commercial so quickly. That indicates that there is a demand for non-lithium alternatives.
The great thing about this battery chemistry is that it can be shipped with a 0V state of charge. I assume this means that it can be non-destructively run down to 0V throughout its service life. If so, then it would be a great candidate for power tools and video cameras. Video cameras tend to be used once a year during the holiday period, and power tools for the home handyman are rarely used at all.
