Estimation Actual

Sony started production 1.2kWh-class energy storage module using lithium-

ion rechargeable batteries made from olivine-type lithium iron phosphate

Tokyo, Japan, June22, 2010 - Sony today announced the development of an energy storage module using lithium-ion rechargeable batteries made with olivine-type lithium iron phosphate as the cathode material (hereafter referred to as 'olivine-type lithium-ion iron phosphate cell'). Key features of olivine-type lithium iron phosphate cell include high power output, long-life performance and excellent thermal stability. Sample shipments of the new module are scheduled to begin from June, 2010. The newly-developed module is an energy storage module with 1.2kWh-class capacity. Multiple modules can be connected either in series or in parallel to easily expand to a higher voltage or capacity. Furthermore, the new module is compatible with stationary power supplies such as UPS (uninterruptible power supply) for data servers or as a backup power supply for mobile phone wireless base stations.
