Resting-Potential-Inspired Solid-State Iontronic Osmotic Power Source Enabled by Polarized MXene

The solid-state architecture of iontronics osmotic power source (IOPS) significantly enhances volumetric power density and eliminates risks associated with leakage and drying up. By making deep use of the ion-electron coupling properties of MXene, the highly integrated electrode design enables the IOPS device to be assembled into a compact osmotic power source using only three building blocks. IOPS arrays can efficiently power commercial electronic devices and show great potential in portable, responsive power systems.
