Abstract

The invention relates to a mercury-free zinc-manganese-carbon paste battery. Its electrolyte is mainly composed of MgCl2 and NH4Cl2, supplemented by three components of ZnCl2. There is no distinction between internal and external electrolytes. Each liter of electrolyte contains the following weight percentages The substance MgCl2 11.0-16.0%, NH4Cl 12.0-14.0%, ZnCl2 6.0-9.0%, the rest is water, add PVA 1.00-2.00g, B(OH) 3 0.20-0.40g, the specific gravity of the electrolyte is 20-25 wave Mido, pH 5.0-6.0. The battery uses a mercury-free corrosion inhibitor, which is mainly boron alcohol resin produced by PVA and B(OH)3, supplemented by 16C or 18C trimethylammonium chloride, or alcohol produced by PVA and B(OH)3 Based on boron resin, supplemented by InCl3 or BiCl3, the present invention realizes the mercury-free battery through the improvement of the electrolyte system and corrosion inhibition technology, and can greatly improve the discharge performance and storage performance of the battery, and can also solve the problem of waste batteries from the source of production. pollution of the environment.

Description

technical field [0001] The invention belongs to the technical field of batteries, in particular to a mercury-free zinc-manganese-carbon paste battery. Background technique [0002] There are two types of zinc-manganese batteries: zinc-manganese alkaline batteries and zinc-manganese carbon batteries. Zinc-manganese alkaline batteries use KOH or NaOH as electrolyte. NH for zinc-manganese carbon batteries 4 Cl and ZnCl 2 As electrolyte, zinc-manganese carbon battery presses NH 4 Cl or ZnCl 2 Two electrolyte systems are formed with different amounts, and the corresponding batteries are called ammonium-type batteries or zinc-type batteries. [0003] There are two types of zinc-manganese-carbon cylindrical batteries: cardboard structure and paste structure. The cardboard structure battery uses pulp paper as the isolation layer. Starch, Flour, Corrosion Inhibitor HgCl for Paste Structure Batteries 2 Mix it with the external electrolyte to form a slurry, and then heat the sl...
