Self-Healing Polymer Could Be Key to Longer-Lasting Batteries
Stanford postdoctoral researcher Chao Wang holds a solid piece of the stretchy, self-healing polymer used to coat and protect silicon battery electrodes. Wang and colleagues at Stanford developed the polymer to help increase the lifetime of the batteries so if they crack under the pressure of use they can repair themselves.

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.
"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."
