Abstract

The invention discloses an application of a zinc-based binary layered composite oxide to a zinc-nickel battery electrode material. The zinc-based binary layered composite oxide is obtained by calcining carbonate type binary zinc-based hydrotalcite; the binary zinc-based hydrotalcite is prepared from zinc nitrate and one selected from trivalent metal oxides. The zinc-based binary layered composite oxide is used as an active substance so that the deformation of a zinc cathode is weakened, the dissolution of the active substance of the zinc cathode is inhibited, the reversibility of a zinc-nickel battery electrode is improved and the service life of the zinc-nickel battery electrode is prolonged.

Description

technical field [0001] The invention belongs to the field of batteries and their applications, and in particular relates to the use of a zinc-based binary layered composite oxide as an electrode material for a zinc-nickel battery. Background technique [0002] Alkaline zinc-nickel secondary batteries have the characteristics of large specific energy, high specific power, stable working voltage, and low price. However, problems such as deformation and dendrites of the active material zinc are the key points that limit the widespread development of this battery. The main cause of these difficulties is the dissolution of the active species in the alkaline electrolyte. During the charging process, the active material zinc deposition is not uniform, which will lead to the current density gradient, which will cause the deformation and dendrite of zinc. Aiming at this problem, people have done a lot of research on the improvement of zinc anode. It is mainly to add additives when ...
