Abstract:
Electrochemical energy storage has attracted much attention due to the common recognition of
sustainable energy development. Transition metal sulfides and post-transition metal sulfides have been
intensively been focused on due to their potential as electrode materials for energy storage applications
in different types of capacitors such as supercapacitors and pseudocapacitors, which have high power
density and long cycle life. Herein, the physicochemical properties of transition and post-transition metal
sulfides, their typical synthesis, structural characterization, and electrochemical energy storage
applications are reviewed. Various perspectives on the design and fabrication of transition and post transition metal sulfides-based electrode materials having capacitive applications are discussed. This
review further discusses various strategies to develop transition and/or post-transition metal sulfide
heterostructured electrode-based self-powered photocapacitors with high energy storage efficiencies
