Long development

Five to 10 years is a long time to wait for this advancement on battery life. But I would guess it will be welcome when it arrives.

Yes, I agree with you, Rob, but you know how long it can take for these things to leave the lab--I think we'll be lucky if we get this in that time frame! It does seem like incredibly useful technology, though, and could be the key to better batteries.

@Elizabeth – yes I think it needs more research and development which might take few years. Waiting for the technology knowing its coming is the worst problem.

That's true, shehan, but better they perfect it and make sure it's working optimally before releasing a half-baked technology.

Yes, I think in terms of big-ticket or popular products like consumer devices, this isn't such a problem anymore because there is a lot of competition pushing companies to get the best product out the first time around. But with batteries especially in terms of all of the experimentation happening, there might be a bit of an adoption curve before the technology is mature.

I think this may be an example of under promise and over deliver.  I suspect we'll see this closer to 5 years from now, not 10!

Our tech development revolution is on an accelerated cycle.  The luxury to develop slowly is almost gone.  If it takes 10 years, it may be irrelevant by then.

This reminds me of self sealing gas tanks on planes.  The technology was invented in 1921, but pretty much languished in the post WWI era.  When WWII started, the application's value became extremely apparent; Allied planes started having the self sealing tanks installed by 1942 and continue to this day.  The difference is an immediate need today.  I hope this accelerates acceptance by battery manufacturers.

That's true, shehan, and what I think is most interesting about this is that while other scientists are working on new chemistries to make batteries last longer, this actually affects the structure of the battery and not the chemistry. It seems also like too easy of a fix for a problem that has been until now seemingly complicated to solve. I guess time will tell.

Shehan, idea is good but all depends up on business and ROI. In current fluxuating market, none of the companies, including giant MNc's don't want to make too much investment for R&D

Those are good questions, shehan, that unfortunately I can't answer. I think these self-healing polymers are fairly new, though, so that may be one reason why.

I find this very interesting:

"The Stanford effort appears to be one of the first to find a new way to improve lithium-ion batteries not by altering the chemistry itself but by adding this self-healing property."

It makes me wonder what studies have been done to conclude that the number of effective charging cycles are reduced because of broken connections versus the battery chemistry itself losing its potential through extended use. While I applaud the concept and can see how it would be helpful when these conditions occur, I don't know enough to understand if this is really a valid solution for general battery use or just a specific failure mode among others. Regardless, the technology is amazing and I admire the work of these researchers - we may very well find some spin-off applications from this research.

I say it will be great to have batteries lasting long while in use, and every one seems 2 be kken 2 see it soon , same goes for me as it will be great not to keep many batteries in resrve for the games, remote , kids toys etc.so looking forward for a rapid development.

Shehan, such technologies are yet to be developed. As of now most of such gadgets cells are in range of 1800-2500mAh. Iof they are able to come up with 5000mAh range cells, it may last long. But I don't know, what's the reason still manufacturers are not looking to such aspects.

That's a really good point, Mydesign. I think this self-healing effort is a good one as well, though, because it will help these batteries last longer in general so they don't have to be replaced. Some people have argued that it's not often long-lasting batteries are replaced but I beg to differ. But you're right, to increase the actual usage time of a battery--ie, how long it holds its charge--is probably an even more important aspect of batteries to be working on.

Elizabeth, if batteries having self healing with fission or fusion technology, then it can be a long last one; otherwise one day it will get drained.

Elizabeth, in both cases atoms are moving and collide to release energy. The same principle of Nuclear reactor.

Elizabath, it's very simple. When atoms get collided each other, it's get broken in to pieces and energy is releasing through these process.

For those of us who work in the design of electronic products, this development is ground breaking and could change or overhaul most of the designs that are currently in the market since it answers one of the biggest headaches in this field; how to ensure lifetime power supply is provided for special components of the device.

On second thought, the fact that there a 'terminator polymer' with conducting properties of its own is yet to be developed still means that it may be a while before large scale use of the new batteries is witnessed. This is because the creation of the current polymer developed by the Stanford team also includes additional costs for the addition of carbon nanoparticles, a fact that will definitely make them more expensive.
