A New Battery Technology will allow Potentially Higher Endurance For RC Aircraft !!

 

The future of RC surely looks promising ...I cant wait to fly with new packs that allow me to fly longer, weigh lighter and most importantly charge faster ...How would a couple of hours of flight time sound like to FPV Fanatics?? Just SUPREME !! .....I was even thinking of air to air battery charging just like air to air refueling..24 hour endurance for MAV's how awesome would that be? ...lets hope these batteries can charge faster than they discharge ...by the sound of it they truly are capable of such a feat...before I go bonkers over this.. I will let you check out this link

Please read the original article again! This is the THIRD time I see people that has misread an re-posted "false" information about this battery technology in various places on the internet. It does NOT improve energy density over normal Li-ion batteries. What it does is to combine the power properties of supercapacitors with the energy density of Li-ion. (if it works as they say).

So no, it will not allow you to fly longer, but might give you the option to charge faster.

Another day, another battery breakthrough.. or not.. amazing how few ever pan out.

It says that the batteries would be 30 times smaller with a discharge rate comparable to that of super capacitors....and the thing about energy density then you need to follow the link in the same article...its about higher energy density aluminium ion batteries i'll post it here and I hope you see what I mean (its called reading between the lines) http://www.extremetech.com/computing/142155-doe-calls-for-a-chemica...

The aluminium ion technology was discarded due to some auto mishaps caused by battery volatility but isn't that the problem lithium ion batteries  too.....we have always given higher energy density priority over higher volatility...

The air to air battery charging was just some wishful thinking on my part ...its not a part of the article that has been linked ...but a battery that can charged as fast as what has been reported ... then my wish will surely be reality..(1+1=2)

It will be 30 times smaller COMPARED TO A SUPER CAPACITOR, not compared to the BATTERIES today. They even have a graph that shows that in the article. Why they and you link to the aluminium article I don't understand. It has very little to do with the technology they showed here.

By checking the original research report you get that the energy density is actually LOWER than many Li-ion batteries we are using today.

(And the faster discharge rates you are reading about is mostly practical on micro batteries which is why they only mention that kind of uses, do some calculation on the currents and you realize a lot of problems on bigger batteries...)

This is a work in progress related article not a finished product on the platter...I wish you just appreciate their intent and the progress that they have made in this field.....and the article clearly says 30 times smaller batteries could be used in wireless devices...now I reckon they don't mean a micro battery...even though they have developed the micro battery now  the article just articulates the potential applications of such a technology of having smaller and fast charging batteries... the aluminum battery link is for high energy density applications and the lithium air battery link is for the high power density apps ..they say that this new battery tries to take the best of both the batteries and tries to do that in just one...even though the energy density is slightly less the higher discharge and recharge rates quickly make up for that disadvantage...

I'm not against research and I know that lab result in something other than products. (I'm a reasearcher myself)

However, I, allergic to people re-posting those lab reports with wrong interpretation spreading false information. You are linking to one article that has already misread the press release. The original press release is talking about micro batteries that will replace supercapacitors rendering in 30 times smaller devices. NOT 30 times smaller batteries.

So yes, if it works, it is a breakthrough for micro batteries, but it is FAR from something usable for DIY drones even when it has left the lab.

Fine.. I'll Let It rest from Here on...
