Producing Lithium-oxide from lithium and oxygen is almost like a type of burning isn't it? Not sure how hot it would get.

Really? I don't like the idea of having to turbocharge anything...more weight and parts to deal with.

A bunch of the comments on that link I posted seem to be talking about just how much oxygen is needed.

THey were also talking about the battery gaining weight as it was discharged (the oxygen bonding with the lithium).

you must admit if a faster better lighter and cheaper power source that lasts 10 times as long as even a nitro comes out bye bye nitro dont try to argue that
Hey VooDoo I'll bet you an Avant Aurora that we don't see betteries that last 10x in your lifetime.

I will believe it when I see it. I wouldn't mind a little longer flights but sixty minutes would make my brain hurt a lot It reminds me of the long main races in nitro rc cars. In the A Main we would run 45 minute races with pit stops and everything. It is real hard to keep focus that long.

It's a complex, costly, glow powered anti-gravity machine!

If 10x longer flight times don't interest you...how about 10x more power lol.

Unless it had a crappy discharge rate. Then you'd need that 10x capacity to get that power. Oh well, that is good for UAV guys like me

Flight Times

Just a note on Fight times and being TOO LONG. Just because a battery will fly for 50 minutes doesn't mean you have to fly for 50 minutes straight. You can still fly your 4-6 minute flights except you will be able to do that 10 times before charging. When I am flying my .50 size Nitro I usually fly half the tank, let my brain recharge then go at it for the second half. C'mon guys really?. Anyway I myself will be more excited when they hit the market for us lowly RC'ers and how much they cost and then have to buy a new charger yet again fer the next big thing. And getting forced oxygen to them will be no trouble at all. I mean we already use fans to cool our helis and nearly anything that moves can force air where it needs to go. Is there any footage or photos of these things in use or even what they look like and how much voltage or capacity they provide per size and weight?

Phil

edit I just saw the second link with the more explanatory article and photo. now I still wonder the voltage and capacity of that prototype cell lighting the LED. They are saying 4000mah per 1 gram. So if it was a 3 cell 4000mah battery it would weigh 3 grams. Assuming it puts out a voltage in 3 volt area that most lithium technologies do It would be like not carrying a battery at all whilst flying your 450 size heli for say 10 minutes. Keep in mind that a typical 3cell 2200mah lipo weighs about 175 grams. You would also in theory require a much smaller motor due to the weight savings increasing efficiency. The next question of course is the discharge rate. Still cool

Nashville.... Wow are you dumb your saying we won't see batterys that last 10x in my lifetime ???? I'm 26 so that means around 50 more years is average and coulds be 70-80 more we went from horse and buggy and no airplane to the moon in 60 your so on... I want my money now tho cuz it's mathmaticly possible so we WILL do it soon just like home computers in 10 years will Be smarter then every human on earth COMBINED but is that really a smart thing to do? Humans do things if there possible wether it's smart or not

The first link given really is just press pulp and says nothing substantial.

The second link has more to say . . . . but still not enough.
http://www.newscientist.com/article...the-energy.html

It says
The team's prototype device has a capacity-to-weight ratio of 4000 milliamp hours per gram – eight times that of a cellphone battery. Even a 10-fold improvement is possible, but tweaking conventional lithium-ion designs will likely offer only a doubling in capacity
Note the "4000mah per gram" fails to specify voltage so actual energy density (WattHrs/gm) can not be quantified.

But what about center of gravity? we would have to put so much lead up front in our helis canopy that the battery would have to be 10 times more powerful anyway, defeating the whole purpose of a lighter more powerful battery to begin with!

I'm happy when 8000+ mAh batteries cost and weigh less than 4200's today, can be recharged at least a 1000 times in 15 to 30 minutes. No need for extra power IMO. One nice improvement would be batteries that wouldn't mind deep discharging.

Ok Voodoo I'll play. It's good to know your age. Based on the naivety of your comments and posts you are much older than I thought you would be. So you believe the movie Terminator is real? Very interesting. I suppose in addition to all of us throwing out our nitro helis now we should destroy our laptops too. Now I understand. And for the record I'm not saying technology is not advancing towards a better power source. We all know it is. I'm saying that just blurting out obscure statements about your opinion on future battery life cycles like it is fact combined with your desire to rid the world of nitromethane (perhaps you have an ulterior agenda, do you enjoy hugging trees?) is again quite naive. While I do enjoy these heated arguments with you as we have done so in other posts it is up to you if you want to continue this civilly or you can continue the name calling? It's up to you. I'm game either way.

Sorry- I just had to reply to this... Remember when the Pentium 100MHz came out? "Oh, there's no way anyone will need more computing power than that..." Well, look at us now! Even if we can't use the power at this moment, surely having it available will drive innovation and technology in the supporting areas of our models.
More power!

haha nash i dont want to get rid of nitro i love the stuff im just saying 1 day it WILL be obsolete that is all its all about power to weight ratio if you can get something lighter more powerful and last longer why would nitro stay? right now its only here for convenience as an electric heli has more pop and power just takes forever to recharge and is expensive nitro is cheap has good power and can fly again in 30 seconds as for terminator theory it is plausible while i don't believe it will happen it COULD theoretically happen but that's another topic

I look forward to hearing your Terminator theories Voodoo. T2 was one of my favorites. And I would love batteries that could last just 10-12 minutes, were affordable and charged fast. It's just not happening fast enough. I've recently tried to get back into the electrics after a 2+year break of only nitro, and I just can't stand these 4-5 minute flights. That and hour plus charging are the only downsides for me at this time. It takes me 5-6 minutes to warm up good on a flight then I really enjoy another 5+ minutes. But that's just me.
