Abstract: The fragility of natural solid electrolyte interphase (SEI) and deformability of naked Li anode cannot meet the requirements on high coulombic efficiency (CE) and long-period cycling for Li metal batteries...

“…Potential impulse technique and AC impedance were performed to calculate the tLi+ value as shown in Figure S15 and Table S1, Supporting Information. [ 44 ] The tLi+ is as high as 0.712 for OA‐MOF/Cu@Li, much higher than that for pristine Cu@Li (0.561), and is responsible for the improvement of polarization performance in Li||Li and Li||Cu cells. The lithiophilic effect inside OA‐MOF can reinforce the dissociation of LiTFSI salt, and allow the access of more flux of free Li + and while expelling the accumulation of anions, lead to the higher tLi+ value.…”

“…The i 0 values for OA‐MOF/Cu@Li and pristine Cu@Li electrodes are calculated via Tafel method. [ 45 ] As shown in Figure S16, Supporting Information, the Tafel curves based on two‐electrode architecture are obtained by linear sweep voltammetry (LSV), and the corresponding linear Tafel region between −100 and −190 mV is fitted by Bulter–Volmer equation: [ 44 ] lni=lni0 +αnFRTη where η represents the overpotential, α, n , F , R , and T represent the charge transfer coefficient, electron transfer number, Faraday constant, universal gas constant, and absolute temperature, respectively, while i stands for the current density. Compared with the low i 0 value of 1.64 mA cm −2 for pristine Cu@Li, the calculated i 0 value for OA‐MOF/Cu@Li is as high as 3.08 mA cm −2 due to the lower interfacial diffusion barrier.…”

“…Inorganic materials such as metal chloride perovskite and carbon can shield Li from liquid electrolyte and allow fast Li + shuttle ( Yin et al, 2020 ). For example, Wu Q. et al (2021 ) proposed an oxygen defect-rich carbon with MgO x domains as a 3D monolithic host and artificial SEI film simultaneously. However, inorganic artificial SEI is prone to fracture due to volume variation of lithium.…”

“…11−13 Constructing a firm artificial solid electrolyte interphase (SEI) from a nano-/ microscale regulates the uniform deposition of lithium ions. 14,15 Besides, three-dimensional current collectors are also used as the host material for metallic lithium to adjust the regular exfoliation and deposition of metallic lithium. 16,17 The abovementioned methods are usually cumbersome, costly, and difficult to prepare in large quantities.…”
