Abstract

The invention discloses a natural product electrolyte composition comprising a nitrogen-containing derivative of a polyphenol, an anthracene phenol compound, an alizarin derivative, an amino acid derivative and an aesculetin. In addition, the invention also discloses the use of the above composition for an electrolyte of a zinc-manganese battery, and a zinc-manganese battery in which the electrolyte comprises the composition. The composition of the invention has excellent corrosion inhibition effect, good conductivity, low temperature resistance and high temperature resistance; When used as the electrolyte of the zinc-manganese battery, the self-discharge performance of the negative electrode material can be suppressed in the non-working state, thus the self-loss of the battery can be reduced, and the service life of the battery can be greatly prolonged. However, the normal battery performance can be exerted due to the good electric conductivity in the battery operation. More importantly, the composition does not contain heavy metal mercury, avoiding heavy metal pollution that may be caused by discarded batteries, and reducing follow-up treatment costs and environmental pollution risks.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a composition of a natural product electrolyte, an application of the composition and a zinc-manganese battery comprising the composition. Background technique [0002] Zinc-manganese batteries are the most widely used batteries, and the world needs more than 50 billion batteries every year. After use, a large number of waste batteries enter the environment, posing a great threat to soil, groundwater, and water sources. [0003] Zinc-manganese batteries are composed of zinc, manganese dioxide, diaphragm, and electrolyte. In the use of batteries, in order to inhibit zinc self-discharge, mercury is often added to inhibit zinc corrosion; among them, ammonium chloride, zinc chloride, and potassium hydroxide are used as electrolytes. When the battery is used up and enters the environment as waste, the chemical electrolyte, especially the mercury-containing chemical electrolyte, wi...
