Abstract 2D architectures and superior physiochemical properties of MXene offer an exciting opportunity to develop a new class polymer electrolyte membranes by controlling the stacking behavior nanosheets. However, assembling nanosheets into macroscopic stable high‐performance proton conductors is challenging. Here, general strategy reported for achieving MXene‐based heterogeneous via crosslinked cellulose nanofiber/sodium alginate (CNF/SA). Through coordination calcium ions with 1D CNF/SA, abundant hydrogen‐bonding networks are firmly locked network, meanwhile, chains transformed from randomly arranged state long‐range ordered arrangement, such molecular channels collaborate tightly‐stacked jointly guide efficient conduction. Thus, as‐built CNF/SA/MXene (CSM) composite membrane exhibits mechanical (164.7 MPa), conductivity (45.4 mS cm −1 ), power density (49.5 mW −2 low open circuit voltage (OCV) decay rate (0.4 mV h ). The design principle material anchoring through ionic‐cross‐linking mixed‐dimensional assembly can inspire synthesis various ion exchange filtration, transport, sieving, more.
