For anyone that wants to see a real data sheet:Nominal Voltage: 4.0V
High Power and Energy Densities
Cycle Life &gt; 50K Cycles
Capacitance Range: 10F-1200Farads<a href="https:&#x2F;&#x2F;abracon.com&#x2F;product-lineup&#x2F;frequency-control-timing-devices&#x2F;atomic-clocks&#x2F;rubidium-oscillators&#x2F;lic-lithium-ion-hybrid-supercapacitors" rel="nofollow">https:&#x2F;&#x2F;abracon.com&#x2F;product-lineup&#x2F;frequency-control-timing-...</a>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&#x27;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:<a href="http:&#x2F;&#x2F;blog.softwaresafety.net&#x2F;2010&#x2F;11&#x2F;introducing-lithium-ion-capacitor-and.html" rel="nofollow">http:&#x2F;&#x2F;blog.softwaresafety.net&#x2F;2010&#x2F;11&#x2F;introducing-lithium-i...</a>

Large, charged capacitors are pretty frightening. Batteries too, but their discharge rate is limited to the speed of the chemical reaction.

Dumb question but I though capacitors store energy and not power?

Let&#x27;s say you want to make a hybrid car lighter-weight. Where is this useful?Power density and cycle life are truly impressive. Energy density is super low

And no mention of the self discharge rate.

What is a Lithium-ion capacitor?
