Panasonic announced it is planning to market a li-ion storage cell for home use, which can store enough electricity to power your house for about one week. The battery is designed to be used together with photovoltaic panels or other alternative energy sources.
Stressing that Panasonic and Sanyo have already test-manufactured a storage battery for home use, Otsubo said, "We're positioned closest [among firms] to realizing CO2 emission-free daily life."
By making Sanyo its subsidiary, Panasonic plans to accelerate the development of the storage battery, while planning to sell it together with a system that will enable households to check electricity usage on a home-based TV display.
Solar batteries for home use and fuel cells can generate power but cannot store electricity, making the development of a storage battery an urgent task for related businesses.
