New Lithium Batteries from Sony
Posted by Chris Gohlke in "Digital Home Hardware & Accessories" @ 01:30 PM
"Sony Corporation today announced that it has launched a new type of lithium ion secondary battery that combines high-power and long-life performance, using olivine-type lithium iron phosphate as the cathode material. Shipment commenced in June 2009. The Olivine-type lithium iron phosphate used in this new battery is extremely suited for use as a cathode material due to its robust crystal structure and stable performance, even at high temperatures. By combining this new cathode material with Sony's proprietary particle design technology that minimizes electrical resistance to deliver high power output, and also leveraging the cell structure design technology Sony accrued developing its current "Fortelion series" lithium ion secondary battery line-up, Sony has realized a high power density of 1800W/kg and extended life span of approximately 2,000 charge-discharge cycles."
From the full press release, it sounds like this technology will first be showing up in batteries for cordless power tools and other similar applications. But, expect to see it migrate to other mobile devices soon.
