A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery Lithium-ion batteries are commonly used for portable electronics and electric vehicles and are growing in popularity for military and aerospace applications The technology was largely developed by John Goodenough, Stanley Whittingham, Rachid Yazami and Akira Yoshino during the 1970s–1980s, and then commercialized by a Sony and Asahi Kasei team led by Yoshio Nishi in 1991 In the batteries, lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge, and back when charging Li-ion batteries use an intercalated lithium compound as the material at the positive electrode and typically graphite at the negative electrode
