(revised on May 10, 2011)
Starting in the end of April 2011, Sony will begin volume shipments of energy storage modules that use rechargeable lithium-ion batteries made with olivine-type lithium-ion iron phosphate as the cathode material (hereafter referred to as ‘olivine-type lithium-ion iron phosphate cell’). These energy storage modules have a lifespan of over 10 years, excellent safety performance, rapid recharging capabilities and high scalability. Sample shipments of the new module began in June last year and Sony decided to begin volume shipments after rigorous testing and experimentation with various applications.

This energy storage module has 1.2kWh capacity and multiple modules can be connected either in series or in parallel to easily expand the voltage or capacity. When used in conjunction with a control device, the module can be as a backup power supply for data servers or mobile phone reception towers. Alternatively it can be an energy storage system for residential use. In addition, the module can be incorporated into recharging stations for electric vehicles as the technology for the built-in rechargeable olivine-type lithium-ion iron phosphate cells facilitates rapid recharging and high power output. The modules will be sold primarily to system integrators incorporating power supply systems for cluster housing, offices, schools and installers of industrial power supply equipment.
Sony is positioning the energy storage business, for which demand is increasing, as a new cornerstone for its rechargeable lithium-ion battery business, and is aiming for sales of 30,000 units of its 1.2kWh energy storage module in the first year.
[ Background Information ]
In recent years, there has been increasing demand in the energy storage system market for rechargeable lithium-ion batteries, which boast superior energy efficiency, higher power density and excellent storage characteristics, as substitutes for commonly-used batteries made from lead or nickel-cadmium (Ni-Cad). More efficient energy storage systems were developed as part of environmental measures to reduce CO2 emissions, but these modules are also garnering attention for their usefulness as emergency power sources in times of disaster or as load-leveling measures during peak electricity periods.
Sony will begin volume shipments of its rechargeable olivine-type lithium-ion iron phosphate cell energy modules, which are characterized by their long lifespan of over 10 years*1, their advanced performance safety , rapid recharging capabilities, and high scalability. The highly scalable modules enable voltage and capacity to be customized to suit various applications, while the compact body design ensures compatibility with a wide range of uses.
