Problems solved by technology

[0002] The main role of mercury in the traditional alkaline zinc-manganese button cell is to increase the hydrogen evolution overpotential on the zinc surface and amalgamate impurities, thereby reducing the amount of gas evolution at the hydrogen anode. However, mercury is a strong pollutant. If the discarded mercury-containing batteries are not handled properly, they will seriously pollute the environment and pose a great threat to human health. Therefore, mercury-containing batteries are listed as dangerous goods in many countries for management

Embodiment Construction

[0011] Such as figure 1 As shown, the present invention is an environmentally friendly alkaline button battery, which is composed of positive electrode material 1, negative electrode cover 2, negative electrode material 3, sealing rubber ring, positive electrode shell 4, electrolyte and diaphragm paper, in order to effectively prevent zinc in the battery When contacting with other raw materials or metals, gas is generated and expands, and a layer of cupronickel 5 material is electroplated on the inner side of the negative electrode cover 2 of the battery, and a layer of copper alloy material can also be electroplated. The negative electrode material 3 includes pure zinc powder, and high-purity indium hydroxide and indium oxide are added as corrosion inhibitors for reducing the hydrogen evolution potential of the zinc powder. The negative electrode material 3 also includes a thickener and zinc oxide. The positive electrode material 1 includes high-purity electrolytic manganese ...

Abstract

This invention relates to an environment-friendly alkaline buckle battery, which includes anode substance, cathode cover, cathode substance, seal glue ring, anode hull, electrolyte and dissepiment paper, the character of which is that the battery cathode cover inner is plating with a layer of white copper or copper alloy, the cathode substance includes pure zinc powder, and it uses high pure hydroxides indium and indium oxide as inhibitor to lower electric potential where the zinc powder separates hydrogen, the cathode substance also includes thickening agent, zinc oxide and so on. The advantage in this invention is that it can prevent from swelling from the gas produced by the zinc contacting with other materials or metals, and it reduces the gas separating quantity of the hydrogen cathode to satisfy the environmental protection.

Description

technical field [0001] The invention relates to the field of batteries, in particular to an environment-friendly alkaline button battery. Background technique [0002] The main function of mercury in the traditional alkaline zinc-manganese button cell is to increase the hydrogen evolution overpotential on the zinc surface and amalgamate impurities, thereby reducing the amount of gas evolution at the hydrogen anode. However, mercury is a strong pollutant. If the discarded mercury-containing batteries are not handled properly, they will seriously pollute the environment and pose a great threat to human health. Therefore, mercury-containing batteries are listed as dangerous goods in many countries for management. Therefore, how to solve the problem of not containing mercury or containing less mercury in the process of alkaline batteries so that alkaline button batteries can meet environmental protection requirements has become the goal pursued by many merchants and users. Con...
