Core–Shell Cu2O@CuS@NiCo-LDH Composite Electrode

High Capacitance, Long Cycling

This composite leverages the synergy between the core–shell architecture and bimetallic LDH to deliver both high specific capacitance and ultra-long cycling stability, overcoming the trade-off between energy density and cycle life in conventional pseudocapacitive materials.
