Hardware, Embedded Systems "Sony has announced a new type of lithium ion rechargeable battery that combines high-power and long-life performance, using olivine-type lithium iron phosphate as the cathode material. The Olivine-type lithium iron phosphate used in this new battery is a perfect cathode material due to its robust crystal structure and stable performance, even at high temperatures. These bateries have a high power density of 1800W/kg, and [four times the] extended life span of [current Li-Ions, with] approximately 2,000 charge-discharge cycles. What’s most surprising is that the battery will keep an 80% charge retention after those 2,000 charge-discharge cycles, which is very impressive. This new battery is also able to charge rapidly (99% in 30 minutes)." These buckoes will debut in power tools originally, but they'll eventually cross over to be smiling up at you from your cell phone, lappy, and other consumer electronics.

It will be interesting also to see how hard it draws from the outlet to make the 30 min charge, usually its pretty substantial and requires a large charging station (large for consumer use anyways) with heavy duty step up transformers to accomplish this.
