The Infidel World May Have Come Up With A Solution To The Threat Of An EMP Attack

The battery's dead: Scientists invent wafer-thin plastic that can store electricity

The device is essentially a flat super capacitor. The energy density is low compared to a battery.

The current indicated "LED for 20 minutes" is roughly equivalent to 20 milliwatt hours.

Two high end AA cells are roughly 6,000 milliwatt hours. 300 times as much energy.

Two low end alkalines are roughly 3,000 mW hours.

Can this be improved, or is it functioning at capacity considering the material used?

Thanks for getting back to me, by the way.

More questions;

Does it actually have the ability to conduct electricity to some extent?

Would motion increase it's ability to conduct electricity?

M Simon ..true but you have to start somewhere.

As important would be the item's ability to hold that charge over a long period

Capacitors are inherently limited by natural limits on charge separation. Baring some breakthrough, batteries will always be able to store more energy than capacitors because chemistry inherently neutralizes the charge.

If you have been following the EESTOR saga you will note that so far there is no independent confirmation of their claims.

For conducting electricity look into graphene research. A 5X better conductor than copper on a weight basis plus a possibility that it might lead to room temperature superconductors.

This device is a breakthrough in shape. The reason it can reduce battery size is its ability to fast charge and discharge. To get the same ability you would need a bigger battery.

There is a lead-acid battery (whose chemistry is similar - sulfuric acid electrolyte) that has a super capacitor built in. I'm not sure if they are commercial yet.
