Sony Lithium-Iron batteries boost power, lifespan; promise quicker charges

Sony have unveiled a new rechargeable battery which promises rapid charging, high power and extended lifespans.  The new batteries are based on Olivine-type lithium iron phosphate, which enables a high power density of 1,800W/kg together with a lifespan of 2,000 charge/discharge cycles; after that, Sony claim the batteries will still hold 80-percent of their original capacity.

They also rejuice faster, with a 30 minute charge good for 99-percent of total capacity.  Sony plan to use the new batteries in power tools initially, before rolling them out to consumer electronics.  No word on how they compare in terms of price to existing Lithium Ion cells.
