摘要

The practical application of lithium (Li) metal batteries (LMBs) is significantlyhindered by the uncontrolled Li dendrite growth and unstable solid electrolyteinterphase layer, which leads to low Coulombic efficiency and short cyclinglifetime. Constructing protective layers on Li metal surface is demonstrated asa facile and efficient approach to tackle these issues. With superior chemical/electrochemical stability, mechanical robustness, high current density tolerance,and low cost, porous polymers are considered promising candidates as the protectivelayers toward practical Li-metal battery applications. In this review, thefundamental mechanisms in stabilizing Li-metal electrodes, design principles,scalable processing, and recent progress of porous polymers toward practicalbatteries are thoroughly reviewed and discussed. The purpose of the currentreview is to analyze whether applying porous polymers as the protective layersis a more promising option of LMBs, and it also discusses how to practicallyachieve low cost, high-energy-density, safe, and long cycle life batteries.
