Hallo, gentlement:

Few days ago, I found a new 'product' called Bacitor or Lithium Ion Capacitor. You can check what one maufacturer say in their web here:

http://www.jmenergy.co.jp/en/pro...

But I'm interested in this kind of products, and if any one has experience with them. The possibility to buy one is also welcomed, but I can't find anything in the usual suppliers (digikey, Farnell, RS, Mouser).

Anyone has experience?
Anyone know how or where buy one just to check?
Anyone knows how to use it? :twisted:

Thanks in advance,

Guillem.

I dont know the numbers but If I recall correctly I have seen similar parts in the farnell store.
Did you only search on capasitors?
I think Farnell has them under batteries instead of capasitors.

I wonder if these are similar devices

ultracapacitor or "super-capacitor" Long thread here about these devices:

Well, I didn't check out if they are stored as batteries. Not by capacitors for sure, even when they are spec'ed at Farads, not Ah. But the reality is that they are in fact a mix of both worlds.

A DLC (AKA supercapacitor, ultracapacitor, incredibly high unbelieveable value of farads) is a thing sheet of metal with highly porous carbon layers on both sides for each pole, with a thin sheet of insulating, electrolyte saturated material. If this sheet is replaced by a polymer sheet with lithium ions, the same kind used in the Li-pol batteries, and one of the poles is doped with lithium impurities, then you have an hybrid between a DLC and a Li-pol battery. This is some times called Bacitor (battery capacitor) or lithium ion capacitor (LIC). This is the case of the product highlighted here, and an interesting thingie.

Specs are quite interesting for many purposes. Maybe some happy electric car owner can understand some of their advantages.

Maxwell Technologies makes a D cell sized supercap 350F and 2.7V, and they make a bank of them in a box that will handle 125V. It will sink and source 150A or so for some 10s of seconds. For a couple $Thou. I think they rate it at 3600 WattSec. Good for helping an EV getgoing I think.
