Oral (Graduate Student) / Orale (Étudiant(e) du 2e ou 3e cycle)

Tuning positive electrode materials in lithium-ion cells provides a promising means for lowering cost of materials while maintaining safety and energy density standards. Due to the rising cost of cobalt, it is important to find less expensive alternatives. Here we present results from first-principles computations within the formalism of density functional theory examining changes in...

Lithium ion batteries are used in consumer electronics, electric vehicles and grid energy storage.1 New positive electrode materials like LiNi1-x-yMnxCoyO2 (NMC) are required to increase energy density, lower cost and increase lifetime. Conventional NMC has large secondary particles (10 - 15 µm) made of agglomerates of small grains (~ 200 - 500 nm) and is thus called polycrystalline NMC.2 ...

2086. Density Functional Theory Studies on the Role of Electrolyte Additives in Lithium-ion Batteries

Oral (Non-Student) / Orale (non-étudiant(e))

To further progress the adoption of electric vehicles and other high power energy storage applications, it is desirable to develop lithium-ion cell chemistries that offer longer lifetimes at high temperatures and cell voltages, without significantly increasing the cost. The introduction of sacrificial electrolyte additives on the order of a few weight percent is a practical method to form...
