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.
In recent years, there has been an increasing demand for lithium-ion rechargeable batteries, which boast superior energy efficiency, higher power density and excellent storage characteristics, as substitutes for batteries made from lead or nickel-cadmium. Until now, lead-acid and nickel-cadmium batteries have conventionally been used in the stationary power supply market for data server UPSs (uninterruptible power supplies) or as backup power supplies 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.
This energy storage module will be on display at the China International Battery Fair 2010 (held from June 24 to 26, 2010) in Shenzhen.
