Membrane properties are central to the efficiency of such energy conversion; however, conventional ion\u2010exchange membranes often suffer from high internal resistance and limited performance. In this work, we report a Janus membrane engineered from a microporous sulfonated poly(ether sulfone) base coated with a thin, nano\u2010porous, positively charged crosslinked poly(vinyl alcohol)\u2013poly(ethyleneimine) layer. The asymmetric architecture promotes directional ion transport, selectivity, and reduced resistance, leading to high osmotic energy harvesting. The membrane achieved a maximum power density of 0.38\u2009W\u2009m\n                    <jats:sup>\u22122<\/jats:sup>\n                    and a current density of 18\u2009A\u2009m\n                    <jats:sup>\u22122<\/jats:sup>\n                    under a 50\u2010fold KCl concentration gradient at ambient temperature. The power density further increased to 0.705\u2009W\u2009m\n                    <jats:sup>\u22122<\/jats:sup>\n                    upon introducing a 30\u2009\u00b0C temperature differential, attributed to enhanced ion mobility and improved surface\u2010charge regulation. In flow capacitive deionization applications, the Janus membrane exhibited an excellent salt adsorption capacity of 4.21\u2009mg g\n                    <jats:sup>\u22121<\/jats:sup>\n                    at 1.2\u2009V in 1\u2009g\u2009L\n                    <jats:sup>\u22121<\/jats:sup>\n                    NaCl solution, demonstrating efficient desalination performance. These results highlight the potential of the developed asymmetric Janus membrane as a cost\u2010effective and robust platform for simultaneous osmotic energy harvesting and water desalination.\n
