1.2kWh-class energy storage module from Sony

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 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.

Additionally, new applications of lithium-ion rechargeable batteries - such as energy storage systems for efficient energy use and load-leveling - continue to be developed as the installation of new energy generating systems like household photovoltaic systems progresses as part of environmental measures to reduce CO2 emissions.

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.

Main features of the energy storage module

1. High expandability
Multiple modules can easily be connected either in series or in parallel, enabling both the voltage and capacity to be customized to suit various applications

2. High performance safety
In addition to the use of olivine-type lithium iron phosphate cell, which boast excellent thermal stability and storage characteristics, the storage module also contains a built-in self-monitoring function to detect any abnormalities within the module itself

3. Low environmental impact
The long-lasting module can be used repeatedly whilst maintaining a reduced environmental impact
