| 英文摘要 | In lithium-ion and lithium metal batteries, inevitable H2O molecules limit the electrochemical performance. Rather than confining or removing H2O molecules, it is more efficient to quench their activity and thus avoid side reactions caused by H2O. In this study, 2-fluoropyridine (2-FP) containing strong Lewis base active sites was selected as an electron donor molecule to interact with H2O to quench its activity. The 2-FP causes steric hindrance, which obstructs contact between the H2O and other reagents like PF6-, and the reactivity of H2O is decreased because of the reconstruction of its electron orbital. Consequently, both lithium-ion and lithium-metal cells have a prolonged cycling life, and a stable electrode-electrolyte interface is produced with greatly reduced transition-metal dissolution and negligible dendrite formation. |
