Durable Lithium Metal Anodes Enabled by Interfacial Layers Based on Mechanically Interlocked Networks Capable of Energy Dissipation

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 61(52)

Published: Nov. 4, 2022

Solid electrolyte interphase (SEI) has received considerable attention due to its vital role in stabilizing Li anode. However, native and many artificial SEIs often suffer from cracking fragmentation under dendrite impact or long-term repeated volume variation, causing capacity decay. Herein, a mechanically interlocked network (MIN) was innovatively designed as interfacial layer protect anode by incorporating the unique energy dissipation capability, which helps survive variation during cycling. As result, symmetric cell with MIN-coated (MIN@Li) exhibited prolonged cycling life of 1500 hours at 1 mA cm-2 . The full using LFP cathode (13.5 mg ) cycled stably for 500 cycles retention over 88 % (1 C). Our results highlight creative application MIN anode, capability promises future success other battery fields suffering variations.
