Development of High Capacity Olivine-Type Lithium Iron base Li-ion Rechargeable Batteries by SONY
Sony has just unveiled its new 1.2kWh-class energy storage module which has been manufactured using lithium-ion rechargeable batteries where their cathode material is made of olivine-type lithium iron phosphate. The reason behind choosing olivine-type lithium iron phosphate based rechargeable batteries is due to their high power output and long-life performance, while providing an excellent thermal stability. The multiple modules can be connected in either series or parallel formation for higher voltage and capacity.
The new power source module is compatible with stationary power supplies UPS for such equipment as data servers or can be used as a backup power supply for mobile phone wireless base stations. The module contains a built-in self-monitoring function for detecting any abnormalities with in the module itself. The new module offers an anticipated longevity of 10 years or more, which is based on one charge-discharge cycle per day. The sample shipment of this new module will commence June 2010.
