Coupled Electrochemical Aging under Non-Uniform Planar Battery Cooling Gradients
Planar cooling gradients split local current density, driving lithium plating at cold cell margins and rapid electrolyte consumption in warm regions.
Electro-Thermal Degradation Modeling for Fast-Charging Large-Format Prismatic Cells
Electro-thermal degradation modeling reveals that internal thermal gradients accelerate localized lithium plating and active inventory loss during fast charging.
Prismatic Cell Spatial Thermal Gradient Generation Mechanisms
Prismatic cell spatial thermal gradients stem from anisotropic heat path resistance and tab current crowding, accelerating localized lithium plating and capacity fade.
Thermal Gradient Effects on Active Material Loss in Prismatic Formats
Internal thermal gradients accelerate prismatic cell active material loss by driving localized current crowding, high-temperature SEI growth, and particle cracking.
