Wood Nanobattery Could Be Green Option For Large-Scale Energy Storage 120
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."

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.

'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.
