Sony Develops 1.2kWh-class Energy Storage Module Using Li-ion Rechargeable Batteries Made from Olivine-type Lithium Iron Phosphate

Sony 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 are said to include high power output, long-life performance and excellent thermal stability.

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.

Sony will bring to market a safe, long-life performance energy storage module using olivine-type lithium iron phosphate cell, which are characterized by their high-power output, long-life performance and excellent thermal stability.

Sample shipments of the new module are scheduled to begin from June, 2010.
