“…[9][10][11][12][13][14] However, the widespread use of LMBs has been hindered by safety concerns, particularly those related to short circuit and thermal runaway issues that arise due to the formation of lithium dendrites that penetrate the separator. [15][16][17][18] To date, much effective effort has been carried out to circumvent the fundamental obstacles and stabilize dendrites of Li anode, such as an artificial protective layer, [16,17] organic/ aqueous electrolyte modifications, [18,19] enhanced SEI layer, [20] configuration separators, [21,22] scaffolding Li, [23] and so forth. Among all reported approaches,the performance of LIBs and their potential for practical application are dependent on adept design of the battery separator.…”

“…Among all reported approaches,the performance of LIBs and their potential for practical application are dependent on adept design of the battery separator. [19] Despite the development of various techniques, such as the application of inorganic composites to coat the surface of polypropylene (PP) separator and their integration into the PP separator medium, the challenges associated with these methods remain unresolved. [20][21][22][23][24] The porous separator is a crucial component of LMBs, and it must possess suitable porosity, excellent wettability, high thermal stability, and low internal resistance to prevent a battery short circuit.…”

A highly flexible, tunable morphology membrane with excellent thermal stability and ionic conductivity can endow lithium metal batteries with high power density and reduced dendrite growth. Herein, a porous Polyurethane (PU) membrane with an adjustable morphology was prepared by a simple nonsolvent‐induced phase separation technique. The precise control of the final morphology of PU membranes can be achieved through appropriate selection of a nonsolvent, resulting a range of pore structures that vary from finger‐like voids to sponge‐like pores. The implementation of combinatorial DFT and experimental analysis has revealed that spongy PU porous membranes, especially PU‐EtOH, show superior electrolyte wettability (472%), high porosity (75%), good mechanical flexibility, robust thermal dimensional stability (above 170 °C), and elevated ionic conductivity (1.38 mS cm‐1) in comparison to the polypropylene (PP) separator. The use of PU‐EtOH in Li//Li symmetric cell results in a prolonged lifespan of 800 h, surpasing the longevity of PU or PP cells. Moreover, when subjected to a high rate of 5C, the LiFePO4/Li half‐cell with a PU‐EtOH porous membrane displayed better cycling performance (115.4 mAh g‐1) compared to the PP separator (104.4 mAh g‐1). Finally, the prepared PU porous membrane exhibits significant potential for improving the efficiency and safety of LMBs.

Porous polymer membranes as separator plays important roles in separating cathode and anode, storing electrolytes, and transporting ions in energy storage devices. Here, an effective strategy is reported to prepare an electrolyte superwetting membrane, which shows good Li+ transport rate and uniformity, as well as electrode‐friendly properties to afford the reduction and oxidation of electrodes. It thereby improves the cycle stability and safety of Li metal batteries. With the arrayed capillaries technique, a thin layer of polyvinylidene fluoride (PVDF) and polyacrylonitrile (PAN) composite is uniformly coated on the surface and pores of polypropylene (PP) membrane with a total thickness of 30 µm. After treating it with n‐butyllithium and LiNO3 in turn, a chemically inert membrane with efficient and uniform ion transport is prepared, and the cycle stability of Li||Li symmetric cells is up to 1500 h, 4 times higher than that of PP membrane. Moreover, the Li||LiFePO4 with as‐prepared membranes achieve a higher capacity retention rate of 92% after 190 cycles at a current density of 3.6 mA cm−2 and a capacity of 3.6 mAh cm−2, and the Li||NCM721 batteries achieve a capacity retention rate of 71% after 600 cycles at a current density of 1.8 mA cm−2.
