- Biomimetic Spring Effect Construction to Stabilize Electrode/Electrolyte Interface for High‐Performance Lithium Metal Anodes Zhenghao Zhao Tingting Su Tianyi Yang Zhengzhe Liu Wenfeng Ren Runcang Sun ChemSusChem Lithium (Li) metal anode is the most promising anode for the next‐generation high‐energy storage batteries due to its high theoretical specific capacity and low redox potential, while its commercial application is plagued by notorious dendrite formation and instable electrode/electrolyte interface degradation. Inspired by the spring effect of cholesterol (Ch) in phospholipid bilayers to maintain cytomembrane structure, a self‐assembled biomimetic spring (SABS) layer is constructed as an artificial solid electrolyte interphase (SEI) layer on Li anode through electrolyte additive engineering. SABS layer is self‐assembled by the reaction of hydroxyl group with Li anode and the intertwining of rigid region with SEI, which can resist volume change of Li anode during plating/stripping processes to maintain SEI structure and induce the uniform deposition to hinder dendrite growth. As a result, Li anode with SABS displays stable plating/stripping reversibility and long cycle‐life over 4800 h. Li–S full battery with SABS still retains a capacity of 410 mAh g −1 after 900 cycles at a current density of 1C and exhibits excellent rate performance of 390 mAh g −1 even at 3C. This work opens a new avenue to stabilize electrode/electrolyte interface via biomimetic spring effect for achieving high‐performance Li metal anodes. 10.1002/cssc.202502113 http://onlinelibrary.wiley.com/termsAndConditions#vor
