Well, according to fareastgizmos, Professor Cho Jae-phil of the Department of Applied Chemistry at Hanyang University in Korea has discovered a developmental technology that aims at adding eight times the battery life.
According to the site, silicon is the main improvement:
Graphite, which is used in cathodes, can store a limited amount of lithium ion, cutting usage time to around 2 hours. The eight-fold increase in storage capacity was achieved by using silicon instead of graphite.
So, when will we see this technology come to the shores? Well, unfortunately, according to a Symbian Freak article, Cho doesn't expect production to begin commercially for four or five years.
