Wood Nanobattery Could Be Green Option For Large-Scale Energy Storage
cylonlover writes "Li-ion batteries may be ok for your smartphone, but when it comes to large-scale energy storage, the priorities suddenly shift from compactness and cycling performance (at which Li-ion batteries excel) to low cost and environmental feasibility (in which Li-ion batteries still have much room for improvement). A new 'wood battery' could allow the emerging sodium-ion battery technology to fit the bill as a long-lasting, efficient and environmentally friendly battery for large-scale energy storage."
The rest of us call it charcoal...
“He’s not deformed, he’s just drunk!”
Which has absolutely nothing to do with the subject. The article is well worth reading. What's kept NA-ion batteries away is that their anodes only last 20 cycles. They solved the problem with wood fibers covered with carbon nanotubes, and these can stand hundreds of cycles.
Again, TFA is worth reading.
Now waiting for the inevitable "that article gave me wood" joke...
Free Martian Whores!
FTR, use of the phrase "[object X] is/are (a) thing(s) of the past" kind of implies that the replacement technology is already here and adopted en masse...
That said, I'm not seeing a whole lot of graphene supercaps for sale on Amazon these days; hopefully soon.
An enigma, wrapped in a riddle, shrouded in bacon and cheese
The use of wood is minimal and is only used as a flexible inner core for what is primarily a carbon nanotube anode. The majority of the battery is still inorganic materials.
(But, hey, one can't expect the first post to have actually read the fine article.)
If it's for-profit but free, you're not the customer -- you're the product (e.g., the Slashdot Beta's "audience").
'All' we have to do is increase their energy density by a factor of 10, get rid of leakage, and come up with a giood way to keep them from discharging all at once without exploding or degrading their performance too badly.
They may well get there one day, but not today.
Shit that article not only gave me wood but made it swell 420% over normal capacity!
Pity that your tube was so nano to begin with...

Well, Amazon has graphene and they have supercaps, so just buy them together for a nifty savings. Also, given the clever and unexpected ways UPS can mangle a package, odds are good that eventually they would arrive fused into a workable single item.
