Paper-Thin Batteries Provide Bendable Power
SkinnyGuy writes "New carbon nanotube-based technology could literally allow companies to paint layers of electricity-holding lithium-ion on standard pieces of paper. The possibilities are endless." You can also read the actual paper.

From wikipedia: The specific energy for NiMH material is approximately 70 Wh/kg (250 kJ/kg), compared to 40-60 Wh/kg for the more common nickel-cadmium, or 100-160 Wh/kg for Li-ion.
This looks like it would be comparable to Li-ion and an improvement over NiMH and NiCd.
Yes it's an anecdote! Were you expecting original research in a Slashdot comment?
1 Wh/kg = 1 mWh/g
Researchers at Rensselaer Polytechnic Institute produced "paper batteries" on nanocomposite paper with an energy density of about 13Wh/kg back in 2007. You can see the paper here.
