Carbon-coated CoAl-LDH@NF composite electrode material and preparation method thereof

摘要: The invention discloses a carbon-coated CoAl-LDH@NF composite electrode material and preparation method thereof. disclosed by the comprises steps of firstly utilizing cobalt nitrate aluminum as source an foamed nickel substrate obtaining Co-Al LDH@NF after one-step hydrothermal; then glucose or cane sugar carbon to coat performing hydrothermal treatment obtain LDH@NF@C. According invention, substep hydrothermal-drying is utilized, technology required equipment are simple, raw materials rich in source, reaction temperature lower, high-temperature carbonization avoided, large-scale production easy achieve. LDH@NF@C composition obtained through has good thermal stability, high crystallization degree large specific surface area, further strong morphology controllability one ideal energy materials.
