The present invention relates to an electrode material for a disposable alkaline battery comprising an anode material and a cathode material, a separator between the anode and the cathode, an alkaline electrolyte, an anode current collector, a gel; the cathode material comprises cathode active materials of manganese dioxide, hydroxyl nickel oxide and conductive carbon particles; the anode material is zinc or zinc alloy and graphite.
Description
Technical Field
The invention belongs to the field of batteries, and particularly relates to an electrode material of a disposable alkaline battery.
Background
A disposable alkaline battery includes an anode, a cathode, an electrolyte permeable separator between the anode and the cathode, and an alkaline electrolyte. The anode comprises an anode active material, now predominantly zinc or zinc alloy particles and a conventional gelling agent for fixing the zinc particles in suspension so that the zinc particles can contact each other, an anode current collector inserted into the gelled zinc electrode, an alkaline electrolyte, typically an aqueous solution of potassium hydroxide, also sodium hydroxide or lithium hydroxide, and a cathode comprising a cathode active material comprising manganese dioxide or nickel oxyhydroxide or mixtures thereof and a conductive additive such as graphite and the like.
The current disposable alkaline batteries are limited by commercial models, the capacity in the batteries is fixed, in order to increase the battery capacity, i.e. the service life of the batteries or the higher power consumption of the batteries to meet the requirements of some high-power electric appliances, the method of increasing the interfacial surface area of the electrode active materials and increasing the active materials in the batteries are generally adopted, and the method of increasing the density of the active materials generally cannot meet the requirements of high power because the electrochemical reaction rate is reduced in the discharging process due to the increase of the density after the density of the active materials reaches a certain degree.
Another problem of the zinc-manganese disposable alkaline batteries mainly used at present is that the batteries have a characteristic inclined voltage characteristic, that is, the average operating voltage of the batteries gradually decreases when the batteries are discharged, and the voltage decreases at a significant rate when the batteries are consumed at a high power, so that the actual battery capacity of the zinc-manganese batteries obtained at a high power is smaller than that of the batteries consumed at a low power, and therefore, the zinc-manganese batteries are not suitable for high-power-consumption electric appliances such as cameras and the like. In order to realize disposable alkaline batteries that can be used at high power, disposable alkaline batteries have been produced mainly using nickel oxyhydroxide as a cathode active material or using nickel oxyhydroxide and manganese dioxide in a weight ratio of 1: 1 as a cathode active material, but nickel oxyhydroxide is much more costly than manganese dioxide.
After the existing disposable alkaline battery is used, whether manganese dioxide or nickel oxyhydroxide is used as a cathode active material, 15-25% of zinc in the original weight in the anode of the battery is not reacted and is discarded. It has been found that the problem caused by this is not that the zinc in this proportion is not discharged by reaction but that when the zinc in the battery reaches this proportion, the chemical reaction rate is lowered due to the increased resistance in the battery and the generated electricity is not put into practical use, and such unusable battery still undergoes a slow electrochemical reaction until the anode active material or the cathode active material in the battery is completely reacted.
Therefore, there is a need for a disposable alkaline cell that has a longer service life at high power and more complete reaction of the materials within the cell.
Disclosure of Invention
The main object of the present invention is to reduce the production costs while ensuring that the disposable alkaline battery is suitable for high power consumption and has a service life similar to that of nickel oxyhydroxide as a cathode active material.
Another object of the present invention is to reduce the consumption of resources by allowing the cathode and anode active materials in the battery to react as thoroughly as possible at the end of the battery's life.
The invention is realized by the following technical scheme:
the percentages referred to in the present invention are percentages by weight.
An electrode material for a disposable alkaline cell comprising an anode material and a cathode material, a separator between the anode and cathode, an alkaline electrolyte, an anode current collector, a gel; the cathode material comprises cathode active materials of manganese dioxide, hydroxyl nickel oxide and conductive carbon particles; the anode material is zinc or zinc alloy and graphite; the graphite accounts for 5-10% of the weight of the anode material; the manganese dioxide accounts for 85% -90% of the cathode active material; the nickel oxyhydroxide accounts for 10 to 15 percent of the cathode active material; the conductive carbon particles account for 30% -35% of the cathode material; the concentration of the alkaline electrolyte aqueous solution is 53-60%; the gels accounted for 3% of the anode and cathode materials, respectively.
The anode material of the alkaline battery contains 0.01-0.03% of metal or metal oxide for preventing hydrogen generation, wherein the metal or metal oxide refers to one or two of bismuth, indium and germanium and aluminum or aluminum oxide.
The anode material of the alkaline battery comprises 0.015-0.025% of aluminum in zinc or zinc alloy.
The alkaline electrolyte is potassium hydroxide, sodium hydroxide or lithium hydroxide.
The beneficial effects of the invention are:
by the technical scheme, a certain amount of graphite is added into the anode material, so that the phenomenon that the oxide surface layer generated after the reaction of zinc in the anode obstructs the reaction speed and reduces the transmission speed of electrons at the later stage of the electrochemical reaction of the battery can be effectively prevented, the chemical reaction can be stably carried out, and the voltage stability is ensured.
2, by using a small amount of nickel oxyhydroxide in the cathode active material, while a certain amount of reaction rate can be increased, the amount of nickel oxyhydroxide used in the prior art is reduced, and the completeness of the reaction is improved by using a high concentration of electrolyte.
Detailed Description

In this embodiment, the selected alkaline electrolyte is 53% -60% potassium hydroxide aqueous solution, and the concentration of this selected alkaline electrolyte solution is higher than the 40% -50% electrolyte solution used in the prior art, through the analysis of the inventor, if the concentration of the used electrolyte is low, it is a cause that the voltage is rapidly decreased in the later period of the battery service life, and if the concentration of the electrolyte is too high, it will affect the initial efficiency of the battery, and through the research of the inventor, when the concentration of the electrolyte is 53% -60%, the best efficiency of the battery can be achieved, especially when the concentration is 55%.

The separator is a material for separating the anode and the cathode without change from the prior art.
The cathode material comprises cathode active materials of manganese dioxide, hydroxyl nickel oxide and conductive carbon particles; the manganese dioxide accounts for 85% -90% of the cathode active material; the nickel oxyhydroxide accounts for 10 to 15 percent of the cathode active material; the conductive carbon particles account for 30-35% of the cathode material, the amount of the nickel oxyhydroxide used in the invention is 0.2-0.3 times of that of the prior art, and the part of the nickel oxyhydroxide can also realize the purpose of improving the cathode reaction efficiency, and the technical improvement of the anode and the electrolyte of the technology is matched to realize that the battery can be suitable for high-power electric appliances.
