A general strategy to achieve high-fidelity electron-ion transduction

In a recent study published in Matter, Yao et al. propose a general strategy to resolve the intrinsic conflict among capacitance, conductivity, and mechanical properties in conventional electrode design by rationally designing the porous structure of conducting polymer hydrogel at micro- and nanoscales. Distinct from the inert metal electrodes, the designed conducting polymer hydrogel electrode renders high-fidelity ionic-electronic transduction and interfacial stability, paving the way for developing next-generation ionotronics devices.
