Scientists print out super-slim battery

Amperage

We don't want to know voltage, what's their capacity (Amperage)?

Very little I suspect.

hmm, not rechargable

looks like it might be quite usefull when they make it rechargable, disposable ones seem rather wastefull these days.

Excellent idea, but I have one reservation

Being zinc-manganese (Basically a leclanché cell), the shelf life would probably be limited, and they don't handle extemes of temperature well. Still, new technology is always good :-)... isn't it?

Impressive

"By placing several 1.5V printed batteries in series, higher voltages of 3V, 4.5V and 6V can also be achieved, the boffins claimed"

I would be mightily impressed if that wasn't possible, seeing as it works with every conceivable battery currently... In fact, technically a 'cell' is the 1.5V source and a 'battery' is a collection of cells.

Fraunhofer Research Institution.

These guys are good. Bloody good.

Remember MP3?

>By placing several 1.5V printed batteries in series, higher voltages of 3V, 4.5V and 6V can also be achieved, the boffins claimed

Whooohoo- BREAKTHROUGH!!! Can they do 7.5 or even 9V?

Scale?

Mmmmm I see. My determination of that picture is that the battery is somewhere between 6.5 and 7 MILES long!

Why did they even bother putting a ruler in shot if its got no scale! Thats the point of putting rulers next to things in photos!

In reality it could be 6.5 or 7 inches, or centimetres, or one of those obscure units of scale, who knows!?

This is nothing...

This is nothing but a thinly veiled grab for power...or thinly printed perhaps.

They missed an obvious application...

... the Government should require high powered versions to be built into ALL clothing with a remote control available to all Police and they won't have to bother giving cops tasers any more...

@ Stu

I make it about 6.5 siriometers, which make the size more impressive than the battery itself

Smaller than potato battery

A zinc-manganese battery? Really? That's the ancient "Super Heavy Duty" battery that every electronics device recommends against using because of the low current output, low power density, leak risk, and high self-discharge.

Fraunhofer Research says it would be good for bank cards. Do I detect sarcasm there?

El Reg Standard Units

That must surely be in reg std units - thus it is an impressive 6.5-7 Wales

Is it just me?

...or does the sample pictured look like

A PAIR OF BOLLOCKS

It would be more marketable if they had one terminal in the center of each pad.

Please can i buy some double-D rechargeable nipple cells?

Paris cos her batteries are flat-packaged

looks like a maxipad

The thing looks like a maxipad, maybe they should remarket it as a joypad.

Yea, more crap we don't need that can't be recycled

Anything that adds to poisonus landfill is good by me, will give something for future archeologists to talk about.
