You would expect some big steps done in that side, thinking in who's interest it's improve batteries just now and how much R&D money they are ready to put there.
The products based on the innovations and groundwork done today will be commercially available in 10..15 years.
This is just like SW development (if you are more familiar with that) except that in materials development the cycle is far longer. Simplified (a lot) it goesthrough the following phases;
1.) idea -> 2.) basic R&D -> 3.) prototyping -> 4.) manufacturability R&D -> 5.) acceptance testing -> 6.) commecial launch
You do a fair amount of cycling thru 2/3/4/5 phases, sometimes going back to 1 before ever reaching 6.
Remember, the current LiPo technology was first demonstarted in the eighties.

Supercapacitors has been used for long as a replacement for small batterycells in memorybackup.
But when a tiny nonrechargeable lithiumcell has been able to hold the memory for 10years, then a supercap of today only holds the memory for about a month without a recharge.
So a capacitor with a capacity similar to a battery , would be a huge step forward in *replacing* batteries.

I want them to last longer, not charge faster...

Happens everywhere. I love science, but I hate it's never never progress. Didn't Nokia promise us a phone that recharged from ambient energy radiating from TVs, Microwave Ovens, Radios....even car engines?
Same with medical science. Newspaper headline reads "A CURE FOR xxxxxxxxx DISEASE - BUT IT WON'T BE AVAILABLE FOR ANOTHER 10 YEARS!".........10 years later "A CURE FOR xxxxxxxxx DISEASE - BUT IT WON'T BE AVAILABLE FOR ANOTHER 10 YEARS!"

That's the layman's view of the progress of science and technology, which is science applied to RealLife (TM)
Do something for the climate today! Anything!
I don't trust poeple without a Nokia n900...
