High-performance ternary NiFeCo-LDH nanosheets for supercapacitors by cation modulation and sodium dodecyl sulfonate intercalation

Abstract

Layered double hydroxides (LDHs) hold significant promise for supercapacitors owing to their superior redox properties and customizable structure. Nevertheless, LDHs exhibit an experimental specific capacity lower than the theoretical value...

Exchanging interlayer anions in NiFe-LDHs nanosphere enables superior battery-type storage for high-rate aqueous hybrid supercapacitors

“…The enhanced interlayer spacing and nanospheres-like morphology increases the exposure of active sites and facilitates the swift movement of electrolyte ions. In addition, the capacitive and diffusive charge contribution were investigated as per eqn (18): 69–71 i ( ν ) = k 1 ν + k 2 ν 1/2 where k 1, k 2 , and ν stand for the capacitive contribution, diffusive contribution of the pseudocapacitor, and scan rate, respectively.
