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 (olivine-type lithium-ion iron phosphate cell).
Sony said that the energy storage modules have a lifespan of over 10
years, rapid recharging capabilities (90% or more in one hour) and high
scalability. Sample shipments of the new module began in June last year
and Sony decided to begin volume shipments later this month.
This energy storage module has 1.2kWh capacity and multiple modules can
be connected either in series or in parallel to 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 cell 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.
Sony will sell the modules primarily to system integrators
incorporating power supply systems for cluster housing, offices, schools
and installers of industrial power supply equipment.
The company is aiming for sales of 30,000 units of its 1.2kWh energy
storage module in the first year.
