Layered double hydroxides (LDHs) are regarded as the excellent electrode materials for supercapacitors because of their high theoretical capacitance and abundance. However, poor conductivity limited reaction kinetics LDHs restrict practical application severely. Herein, Cu is chosen from groups VIII/IB/IIB dopants Co-based LDH (CuCo-LDH). The designed metal–organic framework-derived hierarchical CuCo-LDH hollow nanoarrays integrated on nickel foam fabricated via a facile in situ hydrolysis method. Consequently, introduction copper significantly enhances local electron density cobalt-based hydroxide, which electronic facilitates charge transfer. Copper doping induces lattice defects, providing more active sites to improve storage capacity. As result, our delivers package-enhanced pseudocapacitive performance. as-fabricated asymmetric supercapacitor CuCo-LDH//AC provides relatively energy 22 W h kg–1 remarkable cycling stability (91.3% after 10,000 cycles) towards applications supercapacitors.

Layered double hydroxides (LDHs) are perceived as a hopeful capacitive deionization (CDI) faradic electrode for Cl- insertion due to its tunable composition, excellent anion exchange capacity, and fast redox activity. Nevertheless, the self-stacking inferior electrical conductivity of two-dimensional structure LDH lead unsatisfactory CDI performance. Herein, three-dimensional (3D) hollow nanocage CoNi-layered hydroxide/carbon composites is well designed anode by cation etching pre-carbonized ZIF-67 template. C/CoNi-LDH has unique 3D abundant pore features, which can effectively suppress sheets facilitate transport ions. Moreover, introduced amorphous carbon layer act conductive network. When employed anode, exhibited high removal capacity 60.88 mg g-1 rate 18.09 min-1 at 1.4 V in 1000 L-1 NaCl solution. The mechanism intercalation pseudo-capacitance reaction revealed electrochemical kinetic analysis ex situ characterization. This study provides vital guidance design high-performance electrodes CDI.
