The invention discloses
electroplating liquid for preparing an aqueous
zinc ion battery negative
electrode and application of the
electroplating liquid, and relates to the technical field of aqueous
zinc ion battery negative electrodes. Aiming at the problems of dendritic
crystal growth and the like of a
zinc negative
electrode in an aqueous
zinc ion battery, the
electroplating liquid is optimized by introducing specific additives, namely L-
xylose (L-
Xylose) and
ribose (
Ribose), and the distribution and thickness of a zinc
coating on the surface of a
copper foil can be adjusted by changing current and electroplating time. According to the zinc negative
electrode material prepared by using the electroplating solution, due to the unique
petal-shaped three-dimensional structure, more
zinc ion deposition sites can be provided, the specific surface area of an electrode can be increased, and the uniformity and reversibility of zinc deposition are remarkably improved. The
binding energy of
copper and zinc in the
copper-zinc compound is high, agglomeration of zinc atoms can be reduced, the
petal-shaped copper-zinc compound can reconstruct a
solvation structure of Zn < 2 + >, a
desolvation energy barrier is reduced, an
electrolyte interface double-electrode-layer structure is optimized, and zinc
dendrite growth is inhibited, so that the efficiency of the battery is improved, and the service life of the battery is prolonged.
