Some company announces groundbreaking new battery - again.

Hi!

I think it would be fun to collect all the threads about the wonderful new batterys we are frequently promised.

Personally, I'd be interested in Toshibas 60 seconds recharge/1000s of cycles battery.
Oh, wait - that was 2007

This has to be most reocuring subject there is which has next to nothing to do with batteries for e flight that are available or even will be for years to com.

New Thread today and most lkey will be 6 more by Monday covering the same announchment.

I wonder if we could go retro and figure out how to fly RC electric planes using SLA PB batteries.


I remember reading about someone in the UK, that just before WWII or maybe during WWII, was flying an electric powered airplane at the time. I wonder what the batteries were. i forget now.

Perhaps we are just all too impatient. Basic research and new technology just takes time.

When I was in high school, a looooong time ago, all we had for electron storage was lead-acid and dry cells. Wasn't much going on there. But by the time I was in college along came alkaline dry cells. Wow, what a vast improvement, but still not rechargeagle.

As RC progressed, rechargeables became a necessity, and we saw the development of NiCds, and not much later NMHs. Do any of you think our electic power systems would be as advanced today if we had not had NiCd and NMH in the 1980s-90s. I suspect we would still be in the Model T days.

And just as we needed moe power with lighter weight along comes the LiIo/LiPo and LiFePo. And more importanly when we needed faster than one hour charge we get 2C, 3C, and now up to 5C charge rates. Damnation, how much more furtunate could we be. Charles and many more have been charging LiFePos at 15C-18C for two years now. Is that not a crowning achievement?. Surely none of us would have imagined that just a few short years ago.

And we continue to see brand new stuff coming down the road at an incredible clip. My audiologist just showed me brand new rechargeable hearing aid batteries already on the market. Too expensive for my pockets, but they will come down. And just what are these, Zinc-Airs. Funny, they have been around for a long time but apparently no one thought of trying to recharge them. Now they are talking of using them in electric autos.

I love and appreciate new technology and like reading about it. Perhaps we do need a dedicated thread to this stuff.

First off no battery technology has ever been developed for RC. We are the bottom of the food chain.

Ni cad batteries(cells) were common back in the late fifties and I tested NiMh cells (packs) for RC Car use in the late seventies , if memory serves me right. It was long before they were approved by ROAR. I am not against new developments I just do not think we need six or more new Threads started here every time someone sees a tech announcement.

That is a good point. What other uses are there for high power, high capacity LiPo battery packs out there?
It is like what are they making all these high power LiPo's for out there, besides us using them in Model Airplanes?
For example what other uses are there for a 6s1p 5000mah LiPo battery pack besides in a model airplane.
It has me wondering why the factories are making all these cells and battery packs. Our model airplane needs has to be only a fraction of what they use them for.

My point is that the technolog is not developed for us.

Dave at Aircraft World(Hyperion) ,Charlie Wang (Thunder Power) ?? (kokam) and others adapted the early LiPolys made for other application to RC. Then they had the cell manafactures to produce larger ,higher C rate cells. There are many military applications for cells such as we use and I image many commerical applications as well. My guess is the less than 10% of all LiPolys produced are used in RC.

Same will happen with other technoligies I would guess. LiFePO4 cells were first produced for cordless power tools not RC. The first fuel cell was made for a car then a Laptop but neither are very common.

Charles, sound to me like you are getting old and senile. Who cares whether the technology was created exclusively for us and RC. Not me, I could care less. So long as I have access to the technology and can use it at prices I can afford, I'm just going to be happy and enjoy. And back two years ago when you discovered A123 cells, you had the same beliefs.

As for posting new technology threads here every few days or whatever,,,,,if I don't desire to read them,,,,I just pass them over like I do most threads. I don't find it to be a problem. We all take the chaff with the grain.

Somehow, I can find other more serious items to complain about without even looking, but then it appears, from your posts of late, you can also. Your posts used to be on my first read list, but lately, you have become quite the sorehead. That's a shame as most of the new readers here could learn reams of good electronic stuff from you, as I did. But, hey, perhaps Red and some of the others who are still willing to share their expertise with the newbies and haven't yet developed an attitude will still be around to make this site the fountain of knowledge and experience that has made it so popular for so long.

It is all about the military and NASA and their ever increasing need for smaller,denser batteries.They are currently demanding nano-particles for many military weapons and aerospace systems and this will be the bright future for battery technology.
