The "Rock-chair" Li-ion battery (LIB) was discovered in the late 1970s and commercialized in 1991 by Sony, which has become the primary way we store portable energy today. To honor the contribution for "creating a rechargeable world," the 2019 Nobel Prize in chemistry was awarded to three famous scientists, John B. Goodenough, M. Stanley Whittingham, Akira Yoshino, who made the most important contributions to the discovery of LIBs. However, this technology is nearing its practical performance limits and extensive efforts are underway to replace LIBs with new electrochemical storage solutions, which are safe, stable, low cost and with higher energy density to power long-range electric vehicles and long-lasting portable electronics.
