![]() Stanley Whittingham, John Goodenough, and Akira Yoshino were awarded the 2019 Nobel Prize in Chemistry for their contributions to the development of lithium-ion batteries. The first prototype of the modern Li-ion battery, which uses a carbonaceous anode rather than lithium metal, was developed by Akira Yoshino in 1985 and commercialized by a Sony and Asahi Kasei team led by Yoshio Nishi in 1991. ![]() John Goodenough expanded on this work in 1980 by using lithium cobalt oxide as a cathode. Stanley Whittingham conceived intercalation electrodes in the 1970s and created the first rechargeable lithium-ion battery, based on a titanium disulfide anode and a lithium-aluminum cathode, although it suffered from safety problems and was never commercialized. NMC and its derivatives are widely used in the electrification of transport, one of the main technologies (combined with renewable energy) for reducing greenhouse gas emissions from vehicles. Lithium iron phosphate ( LiFePOģ-based lithium-rich layered materials, LMR-NMC), and lithium nickel manganese cobalt oxide ( LiNiMnCoOĢ or NMC) may offer longer life and a higher discharge rate. Handheld electronics mostly use lithium polymer batteries (with a polymer gel as an electrolyte), a lithium cobalt oxide ( LiCoOĢ) cathode material, and a graphite anode, which together offer high energy density. Lithium-ion cells can be manufactured to optimize energy or power density. It also sees significant use for grid-scale energy storage as well as military and aerospace applications. More specifically, Li-ion batteries enabled portable consumer electronics, laptop computers, cellular phones, and electric cars, or what has been called the e-mobility revolution. The invention and commercialization of Li-ion batteries are considered to have had one of the largest societal impacts in human history among all technologies, as recognized by the 2019 Nobel Prize in Chemistry. Also noteworthy is a dramatic improvement in lithium-ion battery properties after their market introduction in 1991: within the next 30 years, their volumetric energy density increased threefold while their cost dropped tenfold. In comparison with other rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
