So it's some of the performance of a supercap (hundreds of thousands of cycles, up to million-hour lifetimes with a bit of care, less finicky about soldering) with all of the safety of a LiIon battery? I think I'll give it a miss, although it probably has niche applications like use-once military systems where you're not worried about long-term performance before it disassembles itself.
