Angewandte Chemie International Edition, Год журнала: 2023, Номер 62(26)

Опубликована: Апрель 29, 2023

Lithium (Li) metal anodes have the highest theoretical capacity and lowest electrochemical potential making them ideal for Li batteries (LMBs). However, dendrite formation on anode impedes proper discharge practical cycle life of LMBs, particularly in carbonate electrolytes. Herein, we developed a reactive alternative polymer named P(St-MaI) containing carboxylic acid cyclic ether moieties which would situ form artificial polymeric solid electrolyte interface (SEI) with Li. This SEI can accommodate volume changes maintain good interfacial contact. The presence pendant groups greatly contribute to induction uniform ion deposition. In addition, benzyl rings makes certain mechanical strength plays key role inhibiting growth dendrites. As result, symmetric Li||Li cell P(St-MaI)@Li layer stably over 900 h under 1 mA cm-2 without polarization voltage increasing, while their Li||LiFePO4 full high retention 96 % after 930 cycles at 1C innovative strategy is broadly applicable designing new materials inhibit anodes.
