| Abstract Scope |
2-dimensional metal sulfides are potential electrodes for supercapacitors, yet for the real-world applications, the cycle stability and rate performance requires further improvement. An effective way to improve the rate performance of the supercapacitors is to develop a binder-free high capacitance electrode material with hierarchical and porous architectures. We developed hetrostructure MWCNTs/Al2S3 directly grown on NiCo foam as a binder-free cathode material for supercapacitors. The maximum specific capacitance of MWCNTs/Al2S3 electrode was estimated to be 2484 F/g and energy density of 124 W h kg-1 at a power density of 250 W kg-1, with 97% capacitance retention after 1000 cycles. The symmetric supercapacitor can operate at a potential window of 1.1 V, approximately two times wider than the symmetric device. These results show that the use of binder-free MWCNTs/Al2S3 electrode can potentially be used in asymmetric supercapacitors, leading to improved electrochemical properties. |
