New Paper-thin battery.....

Paper-thin battery may revolutionise electronics - Technology - smh.com.au

"
US researchers say they have invented a lightweight paper battery that could serve as an enhanced power storage device for the next generation of consumer electronic devices."

"It's a single, integrated device," said Linhardt. "The components are molecularly attached to each other: the carbon nanotube print is embedded in the paper and the electrolyte is soaked into the paper. The end result is a device that looks, feels, and weighs the same as paper."

"
Beyond laptop computers, cellphones or digital cameras, the paper batteries would be ideal for use in automobiles, aircraft and even boats because of their light weight, the researchers said. The device is 90 percent cellulose."

"
"The paper could also be molded into different shapes, such as a car door, which would enable important new engineering innovations."

Wow...the possibilities are endless....no more HEAVY batteries to clutter up valuable space.....just roll these new ones out against the hull somewhere under the lining....

So you have can have a new electronic chart that looks just like a real chart. Except it has an on/off switch. Off it is blank paper and when On, the chart appears. Hmmm. The only issue is the electrolite keeps eating the chart table.

If it's rechargable, this might be the beginning of a good idea with practical applications for yachties. I'm curious how much power can be stored in one "unit": let's say, something the size of a sheet of paper. Multipy that by 500 for a book-sized battery? What about weight/volume?

Of course, infant technologies often take a while to develop, but this is worth keeping an eye on.

I've seen a few articles about these batteries, but I have not yet seen any suggestion that they will not be heavy.

Yes, "weighs the same as paper", but the important measure is how much energy you get for that weight, and how much energy for that volume. A regular AA nimh battery is very light, but it would take thousands of them to match the energy in the lead/acid battery in my boat.
