Abstract
The invention discloses a high-efficiency zinc-manganese battery, which comprises an electrolyte, wherein the electrolyte is directly dissolved and suspended in a jelly-like high-molecular polymer solution by adopting zinc chloride and ammonium chloride.
Description
The invention relates to a battery, in particular to a zinc-manganese battery.
In the zn-mn cell, the brucite MnOOH, which is formed differently as a result of the discharge process, is one of the main factors that contribute to the ohmic and concentration polarization of the cell, and the density and thickness of MnOOH formation is in turn directly related to the degree of polarization thus produced. In particular, in P-type batteries, zinc chloride has a lower conductivity than ammonium chloride and a lower ability to penetrate MnOOH, and therefore has a lower performance when discharged for a long period of time at a low current.
The invention aims to provide a high-efficiency zinc-manganese battery with long battery storage time and high energy supply efficiency.
The technical solution of the invention is as follows:
a high-efficiency zinc-manganese battery comprises an electrolyte, and is different from the prior art in that: the electrolyte is directly dissolved and suspended in jelly-like high-molecular polymer solution by adopting zinc chloride and ammonium chloride.
The jelly-like high-molecular polymer is prepared from cellulose, polyacrylamide and polyvinyl alcohol.
The electrolyte comprises the following components in percentage by weight:
0.2 to 5 percent of cellulose,
0.01 to 0.05 percent of polyvinyl alcohol,
0.1 to 0.3 percent of polyacrylamide,
25 to 40 percent of zinc chloride
0.3 to 6 percent of ammonia chloride
The balance being water.
The electrolyte is dissolved and suspended in the high-viscosity jelly-like substance, the substances are quite stable per se, and the water-retaining property after swelling is extremely strong, so that the structure formed by the MnOOH layer can be forcedly changed into a loose state, a quite smooth ion channel is still reserved in the MnOOH layer even in the later discharge period, favorable conditions are provided for diffusion, the utilization rate of manganese in the battery cell is improved by 30-50%, and the energy supply efficiency of the whole battery to the outside is improved successively.
Another advantage of the present invention is: the jelly-like high molecular polymer has the function of inhibiting the migration of heavy metal ions, and the larger and heavier the ion diameter is, the greater the migration resistance is, which is very beneficial to inhibiting the self-discharge of the battery, improving the storage time of the battery and reducing the capacity drop and the gas expansion of the battery after storage.
Still another advantage of the present invention is that the sealing requirements of the battery can be relatively reduced. The invention adopts high viscosity jelly electrolyte, and has small fluidity, so that the water and the liquid cannot leak. Meanwhile, the jelly-like substance has the characteristics of very high density, strong sealing effect and difficult water loss, so that the coated paper is in close contact with the positive electrode and the negative electrode, and large-area oxidation crystallization cannot occur even if air invades, and the production process requirement of the battery is simplified.
The invention is further illustrated by the following examples:
example 1:
the zinc-manganese cell has the same structure as that of common zinc-manganese cell, and is different from that of common zinc-manganese cell in that zinc chloride and ammonium chloride are dissolved and suspended in jelly polymer solution. The specific weight ratio of the electrolyte is as follows:
0.5 percent of cellulose, namely,
0.02 part of polyvinyl alcohol, 0.3 part of polyacrylamide, 35 parts of zinc chloride, 4 parts of ammonium chloride and the balance of water. Example 2: the electrolyte comprises cellulose 4, polyvinyl alcohol 0.04, polyacrylamide 0.2, zinc chloride 28, ammonium chloride 0.5 and water in balance. The rest is the same as example 1. Example 3: the specific mixture ratio of each component of the electrolyte adopts cellulose 2, polyvinyl alcohol 0.03, polyacrylamide 0.1, zinc chloride 40, and ammonium chloride 6, and the balance of water. The rest is the same as example 1.
