From: Intrinsic asymmetric iontronic-interfaces for giant power generation

Schematic illustration of the power-generating process through reversible interfacial-ion oscillation mediated by interfacial redox reaction. The AEPG is composed of IAIs and controllable energy-release gate. The IAIs facilitate ion-electron coupling interaction, and the energy-release gate optimizes the energy conversion pathway, synergistically ensuring giant electric output.
