Graphene Could Kill Lithium-Ion Batteries

So when do I get to hear Scotty asking for more di-Lithium crystals? As always, your article sent me on a tour to educate myself. I mean what are “widow weeds”? Wikipedia says “Widow’s Weeds is the first full-length album by the Norwegian Gothic metal band Tristania”. Thank you, Tina, for corrupting America’s youth with the subtext of black eye-makeup, leather wristbands, and disrespect for elders. Give it up, Tina! Marky-Mark has moved on. I also looked up energy densities. At: http://en.wikipedia.org/wiki/Energy_density I learned that Li-ion batteries (all batteries, actually) have a really, really low energy density – less than 2 MJ/Kg. Li-ion batteries = 0.4 to 0.9 MJ/kg Li batteries = 1.8 MJ/kg Coal = 24 MJ/kg Animal fat = 37 MJ/kg (liposuction fueled cars! Powering America into the 22nd century – “Extra order of fries – I’m going on a road trip.”) Gasoline = 44 MJ/kg...
