Novel Operating Modes for the Charging of Lithium-ion Batteries

Berliner, Marc D; Jiang, Benben; Cogswell, Daniel A; Bazant, Martin Z; Braatz, Richard D (The Electrochemical Society, 2022-10-01)

Conventional battery simulation tools offer current, voltage, and power operating modes. This article presents General Operating Modes (GOMs), which move beyond these standard modes and allow battery models of any scale ...
Theory of Layered-Oxide Cathode Degradation in Li-ion Batteries by Oxidation-Induced Cation Disorder

Zhuang, Debbie; Bazant, Martin Z (The Electrochemical Society, 2022-10-01)

Disorder-driven degradation phenomena, such as structural phase transformations and surface reconstructions, can significantly reduce the lifetime of Li-ion batteries, especially those with nickel-rich layered-oxide cathodes. ...
Beyond Preferences in AI Alignment

Zhi-Xuan, Tan; Carroll, Micah; Franklin, Matija; Ashton, Hal (Springer Netherlands, 2024-11-09)

The dominant practice of AI alignment assumes (1) that preferences are an adequate representation of human values, (2) that human rationality can be understood in terms of maximizing the satisfaction of preferences, and ...
