The "olivine battery power storage system" consists of seven rechargeable battery units, each of which has a capacity of 1.2kWh. Sony expects that the system will be used in place of UPSes (uninterruptible power systems) at data centers and as charging equipment.

Sony Corp had a demonstration of powering a TV with direct current from a storage battery at Ceatec Japan 2010, a trade show that runs from Oct 5 to 9, 2010, in Japan.

The storage battery was the "olivine battery heat-storage module," a lithium-ion rechargeable battery that uses lithium iron phosphate (LiFePO4) as a positive-electrode material. It was announced in June 2010. This time, Sony composed a home-use unit by using the battery (1.2kWh) and adding direct-current and alternate-current output capabilities and circuits to control the output.

The TV used in the demonstration was made by modifying an existing 52-inch TV so that it can be driven with direct current.
