Which is it, 40mJ or 100mJ?  However, in either case this is a very small
amount of energy.  If the battery voltage was 3V, then 100mJ would be a
capacity of 10uA hours.  There are SMD batteries meant for energy harvestin=
g
and the like that can do that.

However, do you really want a capacitor instead perhaps?  100mJ is 45V on
100uF, or 15V on 1mF, so a 20V 1mF cap would do it.  If you start with 20V
on 1mF, you only need to discharge it to 14V to get 100mJ out.

What is the application?
