We report a facile strategy in fabricating fiber membrane with Surface Modified Mo2Ti2C3Tx-Mxene as an advanced anode material for highly durable lithium metal batteries. It is found that solvent free UV-exposure of fiber membrane introduces carboxylic functional groups makes more reliable for Mo2Ti2C3Tx-Mxene fiber membrane electrode with enriched Hydrophilic Surface. As a result, such Mo2Ti2C3Tx-Mxene fiber membrane improves the localized charge transfer beyond the electrode, homogenized electric field. Thus, exhibit excellent long cycling performance with ultrahigh coulombic efficiency of 99.08% at current density of 5 mA cm-2 with fixed cut-off capacity of 1 mA h cm-2 for 650 cycles. Full cells with Li/Mo2Ti2C3Tx||NCM622 deliver a high-rate capability at 0.2C for 200 cycles.
