The design of CNTs@Ni1/3Co2/3(CO3)1/2(OH)·0.11H2O in situ compounded in the nanoscale for all-solid-state supercapacitors.

Ni1/3Co2/3(CO3)1/2(OH)·0.11H2O (NCC) was in situ constructed on the surface of CNTs, which realized the nanoscale recombination of NCC and CNTs. The as-obtained CNTs@NCC composite showed excellent electrochemical performance in both aqueous and all-solid-state electrolyte systems owing to the improvement in the utilization of active materials. This work provides a general duty strategy for improving the combined electrochemical performance of electrode materials for energy storage. [ABSTRACT FROM AUTHOR]
