Sony to Ship 1.2kWh Energy Storage Modules with Lithium-ion Batteries


Sony announced on Monday, April 18 that it will start shipping 1.2kWh energy storage modules with rechargeable lithium-ion batteries with olivine-type lithium-ion iron phosphate as the cathode material

The modules have a 10 years lifespan and feature rapid recharging capabilities, advanced performance safety, and high scalability.

Each module has 1.2kWh capacity and multiple modules can be connected either in series or in parallel to scale up the voltage or capacity.

The module can serve be as a backup power supply for data servers or cell phone reception towers, when used with a suitable control device. Alternatively it can be an energy storage system for residential use.

The module can also be incorporated into recharging stations for electric vehicles as the module technology 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 aiming for sales of 30,000 units of its 1.2kWh energy storage module in the first year. 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.

Lithium-ion batteries have superior energy efficiency, higher power density and excellent storage characteristics when compared to commonly-used batteries made from lead or nickel-cadmium (Ni-Cad).

Energy storage module specifications

Capacity: 1.2kWh
Nominal voltage: 51.2V
Maximum output: 2.5kW
Standard recharging conditions: 2.5 hours at 57.6V / 24A
Dimensions: 432×421×80mm (excluding attachment fixtures and fittings)
