Abstract
A dry Zn-Mn battery's electrolyte contains ammonium chloride (2-6 wt.%), zinc chloride (18-28 wt.%), plant acid (0.5-1.5 wt.%) and aqueous flogopite liquid with Baume gravity of 1.01-1.18 (66.5-79.5 wt.%) and can be used to mix with manganese powder to prepare dry battery. Obtained dry battery features high weight/energy ratio that is 2-2.5 times higher than that of existing ordinary batteries, and no poison and environmental pollution.
Description
The present invention relates to a kind of battery electrolyte and compound method thereof, especially for the electrolyte and the compound method of zinc-manganese dioxide dry cell.
The electrolyte of producing general dry battery at present is to constitute a kind of neutral electrolyte by a certain proportion of ammonium chloride of adding, zinc chloride in the ionized water.Also can in ionized water, add a certain proportion of potassium hydroxide, NaOH constitutes a kind of alkaline electrolyte.Though these two kinds of electrolyte have obtained general application, but in the process of using this class electrolyte, easily generate a kind of precipitation of jelly, this jelly deposits rapidly, destroyed the structure of manganese dioxide (MnO2), hindered the positive active material reaction energy, influence the useful life of battery, caused very big waste.
The object of the present invention is to provide a kind of manganese dioxide utilance height, can make battery that more Zinc-manganese dry cell electrolyte and the compound method of long life are arranged.
The object of the present invention is achieved like this.
A kind of Zinc-manganese dry cell electrolyte, it comprises ammonium chloride and zinc chloride, it is characterized in that it also includes liquid and the plant acid that includes the hydrophlogopite ore deposit.Wherein ammonium chloride is that 2-6%, zinc chloride are that 18-26%, plant acid are that 0.5-1.5%, Baume gravity are that the hydrophlogopite ore deposit liquid of 1.01-1.1BC is 79.5%-66.5%.
A kind of compound method of Zinc-manganese dry cell electrolyte is characterized in that it comprises the steps:
A: high-temperature calcination is carried out in the hydrophlogopite ore deposit, and the temperature of calcining is 1100-1700 ℃, and calcination time is 20 minutes;
B: in the hydrophlogopite ore deposit that will calcine the harmful impurity such as iron of battery are removed;
C, the hydrophlogopite ore deposit that will remove described impurity are put into water and are soaked, and soak time should be greater than 24 hours;
D: use 200 purpose mesh screens to filter, make its Baume gravity that contains the liquid in hydrophlogopite ore deposit reach 1.01-1.1BC by the hydrophlogopite ore deposit of water logging;
E: get plant acid, ammonium chloride and zinc chloride and mix with hydrophlogopite ore deposit liquid after above-mentioned processing, mixed proportion is that plant acid 0.5-1.5%, ammonium chloride 2-6%, zinc chloride 18-26%, plum mother-in-law degree are that the hydrophlogopite ore deposit liquid of 1.01-1.1BC is 79.5-66.5%.
The present invention is applicable to various manganese powders, as electrolytic manganese dioxide or common manganese dioxide.Use its weight of dry cell that the present invention assembled out and the ratio of energy to surpass 2-2.5 times of common batteries, and nontoxic, harmless, safe in utilization.
Embodiment
When the preparation Zinc-manganese dry cell electrolyte, involved plant acid is open in another part patent application of the applicant, and the application number of this application is: 95109022.4.Described plant acid can adopt vegetables such as Chinese cabbage, rape, red bayberry, hawthorn, green apricot or fruit to wash with water totally, and smashes into the mud shape, uses then distilled water immersion 10-15 days, and soaking temperature should be controlled at 10-15 ℃ and be advisable.Will be through the plant acid ready for use of above-mentioned preparation.Get a certain amount of hydrophlogopite ore deposit, the hydrophlogopite ore deposit is calcined under 1100-1700 ℃ high temperature, calcination time is 20 minutes; Impurity such as iron in the hydrophlogopite ore deposit of having calcined are removed; Except that impurity such as de-iron are in order to prevent the infringement of these impurity to battery itself; Water is put in described hydrophlogopite ore deposit soaked, its soak time should be greater than 24 hours; After immersion is finished, re-use 200 purpose mesh screens the hydrophlogopite ore deposit is filtered, make its Baume gravity that contains the liquid in hydrophlogopite ore deposit reach 1.01-1.1BC.
With the plant acid that has prepared, treated hydrophlogopite ore deposit liquid, and ammonium chloride, zinc chloride mixes, and the part by weight of its mixing is: plant acid 0.5-1.5%, ammonium chloride 2-6%, zinc chloride 18-26%, Baume gravity are the hydrophlogopite ore deposit liquid 79.5-66.5% of 1.01-1.1BC.
The zinc-manganese dioxide dry cell that goes out with electrolyte quota of the present invention all is better than present commercially available battery on the major parameter index, its major parameter contrast table is as follows: (with R
