[citation][nom]Hok[/nom]I think they REALLY mangled this up... the issue is CAN you recharge it? in one discharge it can have more the 5 - 10 times the energy... however it doesn't seem to say anything about Recharging...[/citation]
It's not clear at all what they mean. If they compare it with rechargeable lithium batteries then it must be rechargeable. Also they say that it recharges itself while discharging.
Will see! There are lots of great announcements all the time but as you see we are not driving flying saucers yet.
I think I am just having a hard time with how the article was written. If all the article is saying is that they are replacing lithium with carbon, fine. Wohoo! But if they are claiming that the air itself is charging the battery, I have a hard time believing that.
The article was published over 3 years ago...why the lag time? If I read the abstract correctly O2 is produced during charging. Wonder how ozone would react? Solution to pollution in LA basin? Original Article Abstract
dude, all the above posts are hidden (I have to press 'show' to see them). WTF is wrong with this site?
About the battery, indeed, there's no way you can gain energy without first putting energy into it.
Carbon itself is not poison. It is what we breathe out. CO2. Carbon dioxide. So it's only part of what we're breathing.
Carbon my itself (in solid form) isn't poison neither, just like coal it is black. Used in a lot of things, like to strengthen steel, used in cars and motorcycle exhausts, even in musical instruments. That's where we get carbon fiber from.
It's only carbon as a fine powder or dust or gas that is dangerous to humans when inhaling it.
Another brilliant technology that we will never see thanks to greedy corporations that lobby in washington and knock off anyone who threatens the status quo. Just the like prototype cars that were built in the 80's that would run off water; where are those today?
The new idea the researchers are examining is to replace the lithium cobalt oxide electrode in today's rechargeable lithium batteries with a porous carbon electrode. This allows lithium ions and electrons in the cell to react instead with oxygen in the ambient air. Rechargeable lithium batteries are currently comprised of a graphite negative electrode, an organic electrolyte and lithium cobalt oxide as the positive electrode. Lithium is removed from the layered intercalation compound (lithium cobalt oxide) on charging and re-inserted on discharge. The University of St Andrews design replaces the lithium cobalt oxide electrode with a porous carbon electrode and allows Li+ and e- in the cell to react with oxygen from the air. air is just the substrate. this project was started in july 2007 and has a 4 yr term funded by the british. the brits already have tidal generators. now new batteries. maybe we can buy elec from them soon. oceans make the energy, massive air batteries store the energy, then i can buy a block.
