Well, it seems defense mega-corp Lockheed-Martin thinks so. They've partnered with Texas company EEstor, which claims to be on track to produce battery technology by next year that has at least 10x standard lithium ion capacity. Their claims are ambitious enough to be raising more than their fair share of skeptical eyebrows, and cries of "hoax!", but the fact that Lockheed-Martin has, so far, filed for two patents with them at least speaks well of their chances. Green commuter car company Zenn is also working with EEstor on their next generation of vehicles.
Somewhat hilariously (but, I suppose, unsurprisingly, given the secrecy inherent in the workings of Big Industry), the best apparent source of information about the science purportedly underlying this new battery technology is at the Wikipedia article on EEstor. The article suffers from a lack of verifiable sources (bad, bad!) but seems, at least to this layperson, to explain the fundamentals of concepts like permittivity.
