SuperCapacitor Materials | Developing a New Generation of Supercapacitors
Apparently these guys have a new supercapacitor/ultracapcitor polymer and metal electrode material with very high performance (11-20 F/cm2), Potentially equaling Li-ion batteries in energy density. Has some self discharge issues though...

Ohm - The car battery is finally evolving
Supercap battery for cars. Lower total storage, so engine off accessory usage is limited. But, it is smart enough to preserve supercap charge to start the engine. So, if you want a lighter battery, don't use other electronics much when the engine is stopped, and are possibly a cheapskate, this might be appealing.

Preparation of energy storage material derived from a used cigarette filter for a supercapacitor electrode - Abstract - Nanotechnology - IOPscience
So it seems that used cigarette butts reduced via pyrolysis to a dense carbon foam doped with nitrogen,beat commercial carbon used for supercaps and possibly going toe-to-toe with CNT/graphene.

UK Reports Progress to Electric Armor Enhancement to Tanks To Counter Rocket Propelled Grenades
Using localized short circuited supercapacitors to shield against plasma jet shaped charges and RPG's. Other option is to use a non-uniform surface (via a hole pattern) to forcibly tumble projectiles, losing their effectiveness.

Using an ultrasonic liquid metal mixer, these guys supposedly are making a barium titanate ultracap that could go toe to toe with EESTOR, because they can make a fancy metal alloy
