"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.
