Overcoming Chemical and Mechanical Instabilities in Lithium Metal Anodes with Sustainable and Eco‐Friendly Artificial SEI Layer

(NMC622) and S cathodes, respectively over 200 cycles at 1 C rate. Additionally, the water-based green manufacturing and biodegradability of the membrane demonstrated the sustainable development and disposal of electrodes. This work provides a comprehensive framework for the design of an artificial layer chemically and physically regulating dendritic growth.
