Lindsay Cahill is a Canadian chemist who uses Magnetic Resonance Imaging (MRI ) to study metabolic abnormalities in pregnancy. [1] She has published more than 70 articles on her research related to nuclear magnetic resonance in studying electrochemical materials and for imaging animal fetuses and placenta. [2] She has published widely-used protocols for the imaging of mouse brains. [3]
Cahill completed her B.Sc. and Ph.D. in chemistry at McMaster University. In her Ph.D., she used solid-state NMR to study lithium ion batteries. [4] She employed 6Li and 7Li solid-state NMR to study the dynamics of the transport of lithium ions through materials. [5]
After completing her PhD, she held a postdoctoral fellowship in the Department of Physics at Warwick University under the supervision of Mark Smith (physicist). In 2009, she moved to the Mouse Imaging Center at the Hospital for Sick Children. [6] One of her contributions at the Mouse Imaging Center was the identification of a mouse model for autoimmune encephalomyelitis that may serve as a better model for multiple sclerosis in humans than previous models. [7] Prior to her scientific career, she was a captain in the Barrie Safety Patrol.
.Cahill was appointed as an Assistant Professor in the Department of Chemistry at the Memorial University of Newfoundland in January 2020. [8] She received the Discovery Award from the Banting Research Foundation and a Discovery Grant from the Natural Sciences and Engineering Research Council of Canada. [9] [10] In 2022, Cahill was the project leader for a grant from the Canadian Foundation for Innovation to establish the Micro-Ultrasound Lab at Memorial University. [11] She was also named one of the 2022 Future Leaders in Canadian Brain Research Program by the Brain Canada foundation. [12]
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit. Electrodes are essential parts of batteries that can consist of a variety of materials depending on the type of battery.
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. The anode of a conventional lithium-ion cell is typically graphite made from carbon. The cathode is typically a metal oxide. The electrolyte is typically a lithium salt in an organic solvent.
Lithium hydroxide is an inorganic compound with the formula LiOH. It can exist as anhydrous or hydrated, and both forms are white hygroscopic solids. They are soluble in water and slightly soluble in ethanol. Both are available commercially. While classified as a strong base, lithium hydroxide is the weakest known alkali metal hydroxide.
TRIUMF is Canada's national particle accelerator centre. It is considered Canada's premier physics laboratory, and consistently regarded as one of the world's leading subatomic physics research centres. Owned and operated by a consortium of universities, it is on the south campus of one of its founding members, the University of British Columbia in Vancouver, British Columbia. It houses the world's largest cyclotron, a source of 520 MeV protons, which was named an IEEE Milestone in 2010. Its accelerator-focused activities involve particle physics, nuclear physics, nuclear medicine, materials science, and detector and accelerator development.
Lithium orotate (C5H3LiN2O4) is a salt of orotic acid and lithium. It is available as the monohydrate, LiC5H3N2O4·H2O. In this compound, lithium is non-covalently bound to an orotate ion, rather than to a carbonate or other ion, and like other salts, dissociates in solution to produce free lithium ions. It is marketed as a dietary supplement, though it has been researched minimally between 1973–1986 to treat certain medical conditions, such as alcoholism and Alzheimer's disease.
John Bannister Goodenough is an American materials scientist, a solid-state physicist, and a Nobel laureate in chemistry. He is a professor of Mechanical, Materials Science, and Electrical Engineering at the University of Texas at Austin. He is widely credited with the identification and development of the lithium-ion battery, for developing the Goodenough–Kanamori rules in determining the sign of the magnetic superexchange in materials, and for seminal developments in computer random-access memory.
Michael Stanley Whittingham is a British-American chemist. He is currently a professor of chemistry and director of both the Institute for Materials Research and the Materials Science and Engineering program at Binghamton University, State University of New York. He also serves as director of the Northeastern Center for Chemical Energy Storage (NECCES) of the U.S. Department of Energy at Binghamton. He was awarded the Nobel Prize in Chemistry in 2019 alongside Akira Yoshino and John B. Goodenough.
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 lower 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 EV's reached 31%, and of that, 68% was from Tesla and Chinese EV maker BYD production 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 to surpass lithium nickel manganese cobalt oxides (NMC) type batteries in 2028.

David Herman MacLennan was a Canadian biochemist and geneticist known for his basic work on proteins that regulate calcium flux through the sarcoplasmic reticulum (SR), thereby regulating muscle contraction and relaxation, and for his discoveries in the field of muscle diseases caused by genetic defects in calcium regulatory proteins.
Lithium cobalt oxide, sometimes called lithium cobaltate or lithium cobaltite, is a chemical compound with formula LiCoO
2. The cobalt atoms are formally in the +3 oxidation state, hence the IUPAC name lithium cobalt(III) oxide.
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.

Lithium nickel manganese cobalt oxides (abbreviated Li-NMC, LNMC, or NMC) are mixed metal oxides of lithium, nickel, manganese and cobalt. They have the general formula LiNixMnyCozO2. The most important representatives have a composition with x + y + z that is near 1, with a small amount of lithium on the transition metal site. In commercial NMC samples, the composition typically has < 5% excess lithium. Structurally materials in this group are closely related to lithium cobalt(III) oxide (LiCoO2) and have a layered structure but possess an ideal charge distribution of Mn(IV), Co(III), and Ni(II) at the 1:1:1 stoichiometry. For more nickel-rich compositions, the nickel is in a more oxidized state for charge balance. NMCs are among the most important storage materials for lithium ions in lithium ion batteries. They are used on the positive side, which acts as the cathode during discharge.
