Sugar Batteries Could Store 20% More Energy Than Li-Ions
An anonymous reader writes "Scientists at the Tokyo University of Science have developed a way to create sugar batteries that store 20% more energy than lithium-ion cells. Before it can be used as the anode in a sodium-ion battery, sucrose powder is turned into hard carbon powder by heating it to up to 1,500 degrees celsius in an oxygen-free oven."
Except that swapping batteries might be a bit tricky, I can think of a perfect application for these.
First those Japanese DOGS take our island that we never visit.
Now they are taking our sugar for batteries.
I must commit Harry Kerry at once. For honor, and rice.
And I ain't li-on.
So... there's no actual sugar in it, just a carbon/sodium anode. So why call it a sugar battery? Pure asshattery of course!
... or another form of power is a sin.
I cannot find the right words to say how much this offends me. There are plenty of other places to get carbon that does not mean driving up the cost of food for everyone else, especially in poorer countries, like what has happened with corn/maize.

If you carbonize it, it's no longer sugar. You could probably use a host of other substances for the same purpose besides sucrose.
Carbon / Sodium battery not sugar battery. Must be just like Spenda -- We processed sugar so that it is no longer sugar, so we can make a stupid claim that gets your attention because you are fooled into thinking it is somehow made of sugar.
But we're not talking sugar straight out of the paper packet. Before it can be used as the anode in a sodium-ion battery, sucrose powder is turned into hard carbon powder by heating it to up to 1,500 degrees celsius in an oxygen-free oven

if this is supposed to be a new economy, how come they still want my old fashioned money?
[gay-sex-acce5s.com]? Into a slinG unless
If they can argue that carbonizing C_6 H_12 O_6 into carbon with high temperature still allows them to call it a "sugar battery", I argue that my elemental alchemist's transformation into plutonium can also be called a sugar battery.
In America, first you get the sugar then you get the power, then you get the women.
Lost at C:>. Found at C.
Battery tech is growing fast. I saw a PBS show on research that has a pretty good grasp of how to replicate plantlife's ability to convrrt sunlight into sugars. The batteries based on this are already providing all the needs of mid-sized office buildings.
> Except that swapping batteries might be a bit tricky,
Apple would like to get behind this wonderful new technology. Now we must find a judge who will let us patent Sugar. Muhahahahah!
...that a fat (based) battery could store 9/4ths of the energy than a "sugar battery" does. (fat: 9kcal/mol sugar: 4kcal/mol)
FTFY.

Title says it all (sorry, I couldn't resist)
First, regarding the so-called sugar battery;
It's really a sodium-ion battery.
They claim a 20% increase in power storage over a lithium-ion, which probably means a 20% decrease in cost, best case.
Sodium-ion batteries have cycle problems - after about 50 charge/discharges, they typically have 50% of their original capacity. They don't even talk about this, so I'm betting they haven't solved the problem.
Second, about lithium-ion batteries;
Lithium isn't rare - you could extract it from sea water for about 3 times what it costs now. Even at that price it wouldn't mean much to lithium-ion batteries, because despite the name, lithium isn't the primary ingredient, nor is it the most costly.
Envia's breakthrough battery is a lot better at 3 times the energy density and half the cost, and it's a lot closer to market.
Can we artificially produce fat? :-)
If not, perhaps this is a solution to the obesity epidemic. Companies will *pay* you for lyposuction and then use the byproduct to make power
mod this +5 misanthropic
battery..............
(come on dude where are you chiming in????)
....stick your tongue on a nine volt battery...
One minute you're putting sugar in the oven at 1500 degrees, the next the stay-puft marshmallow man is leveling half of New York City
Of course there are leftovers. I was not trying to balance the equations for C_6 H_{12} O_6 on one side and Pu^{238}_1 on the other side. I was using my Alchemist's license, which I keep on hand next to my Poetic License. If I were eco-freakin'-good, I could balance it and take the left-over protons+neutrons+electrons and create plain old {H_2 O} out of it. :)

"sucrose powder is turned into hard carbon powder by heating it to up to 1,500 degrees celsius in an oxygen-free oven."
Sounds exactly like my cooking.
A ton of sugar would cost a lot more than a ton of coal. http://www.mongabay.com/images/commodities/charts/sugar.html . The amount of coal is so abundant still that the market price of it is lower than the cost of raising sugar-cane or sugar-beets and refining them into sugar.
a ton of coal costs from $30 per 2000 lbs in Y2K upto $150 per 2000 lbs in the year 2008, and about $30-$50 per ton in May of 2012.
a ton of sugar would cost about $600 with the world price of sugar at less than 60 cents per kilogram.
(to quote you from another thread) whoosh! I think the joke flew over your head. Patenting alchemy is absurd, like believing in homeopathy. The word "alchemy" is the give-away, me-thinks.
Is it rechargable and having high cycles of charge/discharge just like Li-ion bat?
Sugar batteries won't only store more energy. They'll taste better too!
What makes li-ion batteries expensive is not the li, or other chemicals. Likewise, it is not the labor. It is the expense of heating the li up to 1250C. Now, to create these batteries, you have to go to higher temps In addition, it has said nothing about charge cycles.
I prefer the "u" in honour as it seems to be missing these days.
Found a source:
From page 34:
Materials
LiCoO2 0.62
Separator 0.14
Electrolyte 0.30
Anode 0.24
Materials subtotal 1.28
Overhead 0.15-0.25
Direct labor 0.18-0.24
Total manufacturing cost ~1.70
Per this, the lithium compound is indeed the single most expensive part, but not quite half of the materials alone. If we're forced to separate seawater for it, LiIon cell prices would double.
I don't read AC A human right
I think that there's more to it than just Arpa-E and the feds preventing burial, I think that it's also that there's too much non-car interest and research in battery tech - cell phones, laptops, etc...
Plus, conspiracies aside, you have to remember GM is a car company - it wants to sell cars. It's not an oil company looking to sell fuel it pulled out of the ground. If it can sell an EV for a profit, it'll do so. If it's the only one who can produce economical EVs, it stands to make a killing.
For that matter, most of the 'oil' companies have been busily diversifying themselves into 'energy' companies - investing in solar, wind, and other renewables so they're positioned to make the transition from oil when it becomes logical.

What would you make the anode from K-Ion batteries from?
Run Your Rasberry Pi on Sugar
So first they are not sugar batteries, but batteries with anodes made of carbon derived from sugar. Second, the poster feels they will be good for disolvable electronics for the body, but again you are not disolving sugar but some carbonized derivative of sugar which is probably actually toxic to the body.
Its an epic fail when a \. post doesn't RTFA nor understand the article they are posting.
I haven't thought of anything clever to put here, but then again most of you haven't either.
Either the narration on the clip or the article is wrong, The Japanese group seems to claim 20% increase storage capacity over Sodium Ion not Lithium.
