Crushed Silicon Triples Life of Li-Ion Batteries In the Lab

There's several areas which are ripe for improvement in batteries.

1) Power density.
2) Recharge cycles.
3) Charge time.
4) Charge efficiency.
5) Shelf drain.

Even if a certain technology gives a 10x improvement on one of those, it may turn out to have a negative impact on one (or more) of the others, and therefore not be worth marketing.

Example:
My new battery technology improves cuts charge time in half! It also cuts power density by a factor of 3. In certain, specific scenarios it might still be worth using one of these new batteries, but in general, it's won't be.
