Sony launched today a new type of Li-Ion secondary battery that uses olivine-type lithium iron phosphate as the cathode material. The new batteries combine high-power and long-life performance. Due its robust crystal structure and stable performance, the Olivine-type phosphate is used as a cathode material.
The Olivine-type lithium iron phosphate is combined with Sony’s proprietary particle design technology that minimizes electrical resistance to deliver high power output also leveraging the cell structure design technology. This way Sony created the new series of lithium ion secondary battery named “Fortelion”. The “Fortelion” series has a high power density of 1800W/kg (20A continuous discharge) and extended life span of approximately 2,000 charge-discharge cycles.
The power density of 1800W/kg enables the new battery to discharge large currents, while also providing a stable output of voltage, making it highly suitable for use in motor driven applications such as power tools. The extended life span of 2000 000 charge-discharge cycles makes this new battery ideal for use in a wide range of mobile electronic devices. Another great thing is its charging time. It can be charged to 99% of its full capacity in 30 minutes.
The shipment for the new batteries started in June 2009. By adding this high-power, long-life lithium ion rechargeable battery to its lineup, Sony has certainly strengthened its battery business going forward.
