Khalil Amine (born 1962) is a materials scientist at Argonne National Laboratory, an Argonne distinguished fellow, [1] and group leader of the Battery Technology group. His research team is focused [2] on the development of advanced battery systems for transportation applications. In addition to his Argonne appointment, he is an adjunct professor at Stanford University, [3] Imam Abdulrahman Bin Faisal University, [4] Hong Kong University of Science & Technology, King Abdulaziz University, Hanyang University, and Peking University.
For his contributions in the field of electrochemical materials development, [5] Amine was awarded the Global Energy Prize in 2019, and Scientific American's Top Worldwide 50 Research Leader Award in 2003. [6] In 2017, Amine was chosen as a Fellow [7] of the Electrochemical Society. He is the founder and chairman [8] [9] of the Advanced Lithium Battery for Automotive Application (ABAA) global conference.
Amine received his [4] Ph.D. in materials science in 1989 [4] from the University of Bordeaux in France. After completing his doctorate, Amine did postdoctoral studies at Katholieke Universiteit Leuven in Belgium. Moving to Japan in the early 1990s, [4] Amine held various positions at Japan Storage Battery Company, the Osaka National Research Institute, and Kyoto University, before moving to Argonne National Laboratory in 1998.
● Cathode materials based on the AB2O4 spinel structure have been studied extensively since the mid-1980s due to their stability, high lithium-ion diffusion, and large number of materials that crystallize with this stoichiometry. In 1996, Amine and co-workers reported the synthesis and electrochemistry of the ordered spinel LiNi0.5Mn1.5O4 (1996), a cathode often called "5V spinel". It is notable for its stable high voltage with a typical capacity of 125 mAh/g. The compound operates using only the nickel content as the active redox species while the structure inhibits charge compensation by oxygen evolution.
● Amine and co-workers have been active in the studying the lithium-ion cathode materials termed NMC cathodes (patent issued 2005). The materials structure is based on intergrowths of constituent nano-domains of two closely related layered oxides. They are widely used cathode materials in consumer electronics and electric vehicles. [10] NMC technology has been incorporated into multiple batteries types around the world including those that powered GM's Chevy Volt and Bolt. [11] [12] [13] [14] [15] Depending on the lithium content, these materials show an activation step on the first charging cycle that creates a heterogeneous electrochemically active material with capacities greater than 220 mAh/g.
● One of the instabilities of NMC cathodes involves the redox activity of the highly charged cations at the surface against the solvent molecules of the organic electrolyte. In 2012 Amine and Prof Yang Kook Sun from Hanyang University, [16] [17] reported an improvement over the standard NMC cathode by devising a synthetic strategy that slightly orders the constituent cations to create a gradient structure that allows for the surface to be less reactive than the bulk. An advanced version of the NMC cathode technology allows for a wide range of formulations and compositions [18] to be created across each particle to increase both energy and stability at high voltage. [17]
● Lithium-air technology, including a new series of catalysts (2007) developed with Larry Curtiss of Argonne National Laboratory for Lithium-air energy storage systems that increase reversibility, was developed to reduce the overpotential observed in air-based systems associated with the needed electron transfer reactions. [19] [20] In 2013 they improved on the system by developing a closed oxygen system that results in a significant simplification of the purification and storage system. The system stores energy in the couple going from superoxide (O2−) anion to the peroxide (O2−2) anion. The net reaction is (LiO2 +Li –-> Li2O2). [21]

A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li+ ions into electronically conducting solids to store energy. In comparison with other commercial 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. Also noteworthy is a dramatic improvement in lithium-ion battery properties after their market introduction in 1991: during the next 30 years, their volumetric energy density increased threefold while their cost dropped tenfold.
John Bannister Goodenough was an American materials scientist, a solid-state physicist, and a Nobel laureate in chemistry. From 1986 he was a professor of Materials Science, Electrical Engineering and Mechanical Engineering, at the University of Texas at Austin. He is credited with identifying the Goodenough–Kanamori rules of the sign of the magnetic superexchange in materials, with developing materials for computer random-access memory and with inventing cathode materials for lithium-ion batteries.
The lithium iron phosphate battery or LFP battery is a type of lithium-ion battery using lithium iron phosphate as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. Because of their low cost, high safety, low toxicity, long cycle life and other factors, LFP batteries are finding a number of roles in vehicle use, utility-scale stationary applications, and backup power. LFP batteries are cobalt-free. As of September 2022, LFP type battery market share for EVs reached 31%, and of that, 68% were from EV makers Tesla and BYD alone. Chinese manufacturers currently hold a near monopoly of LFP battery type production. With patents having started to expire in 2022 and the increased demand for cheaper EV batteries, LFP type production is expected to rise further and surpass lithium nickel manganese cobalt oxides (NMC) type batteries in 2028.
Lithium iron phosphate or lithium ferro-phosphate (LFP) is an inorganic compound with the formula LiFePO
4. It is a gray, red-grey, brown or black solid that is insoluble in water. The material has attracted attention as a component of lithium iron phosphate batteries, a type of Li-ion battery. This battery chemistry is targeted for use in power tools, electric vehicles, solar energy installations and more recently large grid-scale energy storage.
The lithium–air battery (Li–air) is a metal–air electrochemical cell or battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow.
A potassium-ion battery or K-ion battery is a type of battery and analogue to lithium-ion batteries, using potassium ions for charge transfer instead of lithium ions. It was invented by the Iranian/American chemist Ali Eftekhari in 2004.
Akira Yoshino is a Japanese chemist. He is a fellow of Asahi Kasei Corporation and a professor at Meijo University in Nagoya. He created the first safe, production-viable lithium-ion battery, which became used widely in cellular phones and notebook computers. Yoshino was awarded the Nobel Prize in Chemistry in 2019 alongside M. Stanley Whittingham and John B. Goodenough.
Michael Makepeace Thackeray is a South African chemist and battery materials researcher. He is mainly known for his work on electrochemically active cathode materials. In the mid-1980s he co-discovered the manganese oxide spinel family of cathodes for lithium ion batteries while working in the lab of John Goodenough at the University of Oxford. In 1998, while at Argonne National Laboratory, he led a team that first reported the NMC cathode technology. Patent protection around the concept and materials were first issued in 2005 to Argonne National Laboratory to a team with Thackeray, Khalil Amine, Jaekook Kim, and Christopher Johnson. The reported invention is now widely used in consumer electronics and electric vehicles.

The lithium nickel cobalt aluminium oxides (abbreviated as Li-NCA, LNCA, or NCA) are a group of mixed metal oxides. Some of them are important due to their application in lithium ion batteries. NCAs are used as active material in the positive electrode (which is the cathode when the battery is discharged). NCAs are composed of the cations of the chemical elements lithium, nickel, cobalt and aluminium. The compounds of this class have a general formula LiNixCoyAlzO2 with x + y + z = 1. In case of the NCA comprising batteries currently available on the market, which are also used in electric cars and electric appliances, x ≈ 0.8, and the voltage of those batteries is between 3.6 V and 4.0 V, at a nominal voltage of 3.6 V or 3.7 V. A version of the oxides currently in use in 2019 is LiNi0.84Co0.12Al0.04O2.
Lithium nickel manganese cobalt oxides (abbreviated NMC, Li-NMC, LNMC, or NCM) are mixed metal oxides of lithium, nickel, manganese and cobalt with the general formula LiNixMnyCo1-x-yO2. These materials are commonly used in lithium-ion batteries for mobile devices and electric vehicles, acting as the positively charged cathode.
