Profile overview
Who is Yoshio Nishi?
Yoshio Nishi is an inventor associated with Japan. Their documented work in energy & climate includes Sony's first commercial lithium-ion battery, the contribution at the center of this evidence-backed profile.
Yoshio Nishi led the Sony team that engineered the first commercial lithium-ion battery. The group developed the binders, electrolyte, separator, additives, anode heat treatment and large-volume cathode-powder processes needed to turn promising laboratory chemistry into reliable production cells. Sony introduced the resulting battery in 1991 for camcorders and soon for mobile electronics.
