Abstract Over the past decade, concerns over sustainability of lithium‐ion batteries (LIBs) have arisen due to scarcity critical elements such as lithium (Li), nickel (Ni), and cobalt (Co), prompting exploration alternative complementary electrochemical energy storage technologies. Due more abundant resources compared contemporary LIBs potentially higher specific than emerging sodium‐ion (SIBs), potassium‐ion (PIBs) attracted intensive research interest a promising existing Nevertheless, development practical PIBs remains in its infancy. In this perspective, various electrode materials electrolytes reported for from an application point view identifying most ones with high are first concisely discussed. Then, pack‐level energy, density, cost analyses presented several chemistries, which also representative SIBs demonstrate advantages PIBs. After that, succinct discussion is evaluate practicality potassium metal batteries. Finally, challenges associated commercialization PIBs, providing future fronts high‐performance outlined.

Advanced Energy Materials, Год журнала: 2024, Номер 14(15)

Опубликована: Март 5, 2024

Abstract The manufacturing process of Lithium‐ion battery electrodes directly affects the practical properties cells, such as their performance, durability, and safety. While computational physics‐based modeling has been proven a very useful method to produce insights on interdependencies well formation electrode microstructures, high costs prevent direct utilization in optimization loops. In this work, novel time‐dependent deep learning (DL) model is reported, demonstrated for calendering nickel manganese cobalt (NMC111) electrodes, trained with time‐series data arising from Discrete Element Method (DEM) simulations. DL predictions are validated by comparing evaluation metrics (e.g., mean square error (MSE) R 2 score) functional (contact surface area, porosity, diffusivity, tortuosity factor), showing good accuracy respect DEM can remarkably capture elastic recovery upon compression (spring‐back phenomenon) main 3D microstructure features without using descriptors its training. Furthermore, significantly lower cost than simulations, paving way toward quasi‐real‐time loops architecture predicting conditions adopt order obtain desired performance.

In drying of battery electrodes, high speeds are desirable but lead to binder segregation resulting in lower adhesion strength and poorer electrochemical performance. During calendering, the elastic recovery electrode makes it difficult estimate line load required achieve desired porosity. The approach we present incorporates various migration models combines them with a calendering model as Sangros used it. taken from literature put special focus on kinetics, particle dynamics. This information is passed solid-state bridge-based Discrete Element Method, which additionally extended include interactions between coating current collector. Through interaction these models, mechanical behavior by means stress cathodes can be predicted for different degrees compaction well areal loadings.
