This morning Sony announced a new type of lithium ion secondary battery that includes all the major improvements one expects to hear from a new battery including higher power output, extended lifespan and faster charge times. The batteries, which are designed to be used in larger rechargeable batteries like the kind used in power tools (hence the basic label) feature an olivine-type lithium iron phosphate used as the cathode material. As someone who never progressed past high school chemistry I’m not quite sure why that’s a better material to use, but according to Sony it results in a battery that has a power density of 1800W/kg with 20A continuous discharge, a 2,000 charge-discharge life cycle and the ability to recharge up to 99% of its capacity in a mere 30 minutes. And apparently the new batteries have been shipping since June of this year, so thanks for letting us know right away Sony!
