They can be made to charge and discharge faster at the price of their shortened lifetime, but that's not a solution at all. Supercapacitors may offer fast charge/discharge rates, but their capacity is just not very high. A hybrid of these two would be perfect.

Quantumsphere, on the other hand, presented last september a Li-Ion battery with a new that lasts five times more than traditional ones.
