Sony Launches a New Kind of Lithium

Sony on Tuesday announced it has launched a new type of lithium ion secondary battery using olivine-type lithium iron phosphate as the cathode material.

What exactly does that mean? According to Sony, both high-power and long-life performance in a single package. The company claims olivine's robust crystal structure and stable performance make the material an ideal fit for use as a cathode material. In addition, Sony says its new battery technology is able to charge rapidly.

Sony has already started shipping the first battery to use the olivine material, which the company sells under its Fortelion series branding. It holds a capacity of 1.1Ah with 80 percent capacity retention after 2,000 charge-discharge cycles, and is able to recharge to 99 percent of its full capacity in 30 minutes, Sony says.
