Biocompatible Electrodes: Development of Fluorine‐Free Tantalum Carbide MXene Hybrid Structure as a Biocompatible Material for Supercapacitor Electrodes (Adv. Funct. Mater. 30/2021)

In article number 2100015, Sanjiv Dhingra and co-workers demonstrate fluorine-free development of a tantalum carbide MXene-tantalum oxide (TTO) hybrid structure through an innovative and facile protocol. TTO as an efficient biocompatible material for supercapacitor electrodes possesses biocompatibility with different types of human cells, and offers excellent volumetric capacitance, energy/power densities, and cyclability when assembled into a symmetric supercapacitor. It offers excellent promise for future biomedical energy storage devices.
