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. 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.
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. Sample shipments of the new module are scheduled to begin from June, 2010.This energy storage module will be on display at the China International Battery Fair 2010 (held from June 24 to 26, 2010) in Shenzhen.
