Abstract

The invention discloses a Schiff base surface active agent, namely, 2-octanone-p-phenylenediamine, and an application thereof. The structural formula of 2-octanone-p-phenylenediamine is as follows. 2-octanone-p-phenylenediamine is applied to alkaline nickel zinc batteries, used as a corrosion inhibition additive substituted for mercury and used for preventing phenomena of corrosion, dendritic growth, deformation, migration and the like of a zinc electrode. 2-octanone-p-phenylenediamine can effectively prevent an alkaline electrolyte from corroding the zinc electrode; and the cyclic voltammetry and a zinc migration experiment show that 2-octanone-p-phenylenediamine has better inhibiting effects on dendritic growth, deformation and migration of the pasted type zinc electrode.

Description

technical field

[0001] The invention belongs to the technical field of mercury-substituting corrosion-inhibiting additives for alkaline zinc-nickel batteries, in particular to a Schiff base surfactant 2-octanone p-phenylenediamine and its use as mercury-substituting corrosion-inhibiting additives in alkaline zinc-nickel batteries Additive application. Background technique

[0002] With the development of society, the application of secondary alkaline zinc batteries is also increasing. At present, various portable electrical appliances are developing rapidly. Secondary alkaline zinc batteries are widely used in military, aviation, commercial and other fields. However, zinc electrodes generally have problems such as corrosion, deformation, dendrites, and migration under alkaline conditions, which shorten their lifespan. In the past, the homogenization of mercury on the surface of zinc was often used to solve this series of problems, but mercury is a poisonous and harmful subs...
