Sony's certainly had its share of battery problems but, like most battery-makers, it's also doing its part to try to improve things, and it's now announced a new lithium-ion battery that should not only be more stable, but last significantly longer than traditional batteries as well. That's apparently possible in part due to its use of an olivine-type lithium iron phosphate for the cathode material, which should help boost the battery's overall lifespan to four times that of conventional lithium ion batteries, not to mention provide an 80% capacity retention after 2,000 charge-discharge cycles and, perhaps most impressively, a promised 99% recharge in just 30 minutes. According to Sony, the batteries are especially well suited for use in power tools (where they'll first show up), but it does say they'll also eventually be "expanded to a wide range of other mobile electronic devices."
