Spin Effect to Promote Reaction Kinetics and Overall Performance of Lithium‐Sulfur Batteries under External Magnetic Field

Angewandte Chemie International Edition, Год журнала: 2022, Номер 61(49)

Опубликована: Окт. 11, 2022

Abstract Lithium‐sulfur batteries (LSBs) are still limited by the shuttle of lithium polysulfides (LiPS) and slow Li−S reaction. Herein, we demonstrate that when using cobalt sulfide as a catalytic additive, an external magnetic field generated permanent magnet can significantly improve LiPS adsorption ability reaction kinetics. More specifically, results show both experimentally theoretically how electron spin polarization Co ions reduces repulsion enhances degree orbital hybridization, thus resulting in LSBs with unprecedented performance stability. Under field, 0.0084 % per cycle decay rate at 2 C during 8150 cycles produced. Overall, this work not only demonstrates effective strategy to promote electrochemical conversion no additional energy cost but also enriches application effect electrocatalysis fields.
