During his tenure at GS Japan Storage Battery Co., Ltd., Dr. Tsukamoto developed and manufactured the world’s first rectangular Ni-Cd battery and helped the commercialization of the Motorola Micro TAC cell phone and Sony’s cassette case-sized Walkman. In addition, he assumed a leading role in the development and manufacturing of Li-Al batteries for military applications as well as portable thin Li-ion batteries. Dr. Tsukamoto founded Quallion LLC in 1999, and took initiative in projects developing and manufacturing high-reliability Li-ion batteries for medical, aerospace, and military applications. Dr. Tsukamoto was awarded the Technology Award of International Battery and Material Association, the Frost Sullivan Award, and Boeing’s Technology Supplier Award for his outstanding achievements in the field of special applications of Li-ion batteries. Quallion’s human body embedded type storage battery (magnetic remote chargeable) has been implanted in tens of thousands of people. It is expected that all of the batteries in U.S. military satellites will be replaced with the Quallion-made batteries in the future.
Dr. Tsukamoto left Quallion in 2012 and founded CONNEXX SYSTEMS Corporation in Kyoto, Japan aiming to apply his rich stores of knowledge about high-reliability storage batteries to civilian use, especially in the fields of mobile bodies and renewable energy.
