Designing materials having novel electrodes with controlled structure and composition is a big challenge for energy storage applications. Hybrid supercapacitor with improved efficiency in energy density without altering the efficiency in power density has been developed in latest years. Quaternary sulfides have attracted considerable attention in this field, where many methods have been used to improve its performance owing their high electrical conductivity and theoretical efficiency. Appropriate incorporation of carbonaceous materials along with quaternary materials improves charge transfer capacity and durability of synthesized composite materials. Herein, we have focussed to provide an overview on the impact of carbon on the morphological evolution in the quaternary-based metal sulphides carbon composites. Moreover, in this perspective it has also been discussed about the major advantages and drawbacks in synthesizing quaternary composite materials.

Key words: Quaternary sulfides, Hybrid supercapacitor, Carbonaceous materials
