High-performance graphdiyne-based electrochemical actuators.

ABSTRACT: Electrochemical actuators directly converting electrical energy to mechanical energy are critically important for artificial intelligence. However, their energy transduction efficiency is always lower than 1.0% because electrode materials lack active units in microstructure, and their assembly systems can hardly express the intrinsic properties. Here, we report a molecular-scale active graphdiyne-based electrochemical actuator with a high electro-mechanical transduction efficiency of up to 6.03%, exceeding that of the best-known piezoelectric ceramic, shape memory alloy and electroactive polymer reported before, and its energy density (11.5 kJ m-3) is comparable to that of mammalian skeletal muscle (~8 kJ m-3). Meanwhile, the actuator remains responsive at frequencies from 0.1 to 30 Hz wit
