Sony harnesses new technologies to contribute to the realization of sustainable lifestyles and address key issues of importance to society.
As an example, Sony developed an energy storage module with a 1.2 kWh capacity that uses the inherent proprietary technologies applied to such cells. In April 2011, Sony commenced mass production of these modules. Following the Great East Japan Earthquake in March 2011, Japan has seen a rapid rise in interest in the storage of electricity for later use from a broad range of electricity consumers, from infrastructure facilities to residential homes. Energy storage battery technology is thus attracting significant attention from both businesses and households as a means of reducing electricity consumption and as a backup power source in the event of a sudden power outage.
