Following the news last Monday (Dec.21) of their acquisition of more than 50% of the voting stocks of Sanyo Electric Co., Ltd as part of their strategy to be the leader in the industry as an “Environmental Innovation Company” by 2018, news dropped on the Japanese newspaper Yomiuri Shimbun through their interview with Fumio Otsubo, President of Panasonic, that they have already constructed with Sanyo (now a Panasonic Group Company) lithium-ion storage battery for use at homes for a week (obviously Japanese homes are implied). According to the interview, Mr.Otsubo also states that the technology will be commercialized sometime in 2011 and is planned to be available along with a system that will allow users to monitor the electricity usage on TV at their home.
