High-performance super-capacity using activated glassy carbon foam

Abstract

An urgent demand for new sustainable and efficient energy conversion and storage devices required the development of novel electrode materials with increased specific capacitance. However, low mass loading, poor scalability, and low working voltage always limited further practical application of most reported high-performance supercapacitors electrode materials. In this work, we demonstrated the preparation of activated glassy carbon foam as high-performance electrode via oxidizing commercial glassy carbon foam in HNO3 solution.
