Paper Nanotube Battery

Research Professor Yi Cui, (Materials and Science Engineering, Stanford University) here demonstrates a new paper battery that may change the energy storage landscape.

Dip an ordinary piece of paper into ink infused with carbon nanotubes and silver nanowires, and it turns into a battery or supercapacitor. Crumple the piece of paper, and it still works.

We need to bear in mind that this cutting edge development is merely a taste of what may one day be possible! Thus we are left to ponder the issues, such as what the lifespan of the battery is... how soon does the power degrade and are they rechargeable?

Although its conceivably easier to recycle than Lithium or Lead acid, can the nano material be recovered and recycled, if the nano material is toxic, and whether or not the dried nano material creates dust that is hazardous when inhaled ?
