Synthesis of multi metal sulfide based electrode material for high performance supercapacitor

Transition metal sulfides are referred to as good materials for effective energy storage with high electrochemical performance due to their multi oxidation states. Herein, we prepare cobalt-molybdenum-sulfide nano composite denoted as CMS through hydrothermal method. The CMS@NF exhibit great electrochemical performance of specific capacity 112.8 mAh/g and 60 % of capacity retention at 10 A/g current density after 10,000 cycles. These results indicate that CMS@NF is a promising positive electrode material in the field of energy storage technology.
