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.
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.
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.
@far911- At times I tend to think that battery manufacturers have not invested much time and money on research and development. A battery manufacturer surely knows in an out of the batteries they manufacture and the materials used.

Shehan, how does it matter? Everybody is using the same cells with same technology and material.
"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.
@far911- If you think of the applications what not can you use it for? Imagine using this technology to power vehicles. You could drive miles with just a single charge. That's when we really make use of this technology.
Elizabeth, now a day's peoples are using more and more gadgets in day to day life. So I personally feel the requirement of some mechanism to increase the life time of batteries rather than such self healing technologies.
"yes most people use gadgets such as tablets, media players etc. every day. It's always nice to see a long lasting battery."
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.
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.
"The other day I saw a video on these self healing materials, and I was amazed by this invention. Certainly it can find numerous applications in the engineering world specially in the polymer industry."
Taimoor, what's the specialty in polymer industry?
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
