LiFePO4 is not a new (as in research) technology (i came across it when looking into eBikes).. It's just lithium ion battery with a lithium iron phosphate cathode. In practice, this means it trades a little power density for a little longer life.
It could be an interesting option for electronics as power draw continues to fall [eg. would be good in a kindle now], but long life over lighter/longer battery life is a hard sell for both consumers (short termist) and manufacturers (reduced planned obselescence).
