Note that the original data sheets said that these could be wave soldered. ABSOLETLY NOT. Even hand soldering they must be treated with respect, a lot of respect.
One of the major problems with these is there a minimal voltage that they must not go below. Their life gets shortened. I've never seen data on how much.
To my knowledge Li-Ion Capacitors were first introduced to the market by Taiyo-Yuden in 2010. They are no longer in this market. I wrote a blog about it back then:

The more the Farads the higher the leakage. The higher the tempature the higher the leakage.
Power density and cycle life are truly impressive. Energy density is super low
Nominal Voltage: 4.0V High Power and Energy Densities Cycle Life > 50K Cycles Capacitance Range: 10F-1200Farads
