Abstract
An environmental protective alkaline button battery is provided, which comprises anode substances, a cathode pole cover, cathode substances, a ring seal, a cathode shell, electrolyte and diaphragm paper, and is characterized in that: the inner side of the battery cathode cover is plated with a layer of cupronickel or copper alloy, cathode substances comprises pure zinc powder, and indium hydroxide and indium oxide are added as inhibitor to decrease hydrogen liberation potential of zinc powder; cathode substances comprises thickener and zinc oxide, etc. As inner side of the battery cathode cover is plated with a layer of cupronickel or copper alloy, the utility model cupronickel or copper alloy is plated on the inner side of the battery cathode cover, and cathode substances mainly comprise pure zinc powder while indium hydroxide and indium oxide are added as inhibitor, replaced the mode that mercury used as inhibitor to reduce hydrogen liberation potential of zinc powder, the utility model effectively prevents expansion caused by zinc when contacting with other material or metal and produces gas, reduces gas evolution of hydrogen anode, enables alkaline button battery to meet environmental protective requirement.
Description
Technical field
The utility model relates to field of batteries, specifically is a kind of environmental protection alkaline button cell.
Background technology
The main effect of mercury in traditional alkaline zinc margunese button cell is the overpotential of hydrogen evolution that can improve zinc surface, can make the impurity amalgamation, thereby reduce the gassing rate of hydrogen anode, yet, mercury is again a kind of strong pollutant, and discarded contains mercury cell as dealing with the meeting serious environment pollution improperly, health is existed great threat, be put into dangerous material in many countries and manage so contain mercury cell.Therefore, thereby how to solve not mercurous or few mercurous alkaline button cell that makes reaches environmental requirement in alkaline battery technology, then becomes the target that numerous businessmans and user pursue.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems and deficiency, and a kind of alkaline zinc margunese button cell of environmental protection is provided.
The technical solution of the utility model is achieved in that
A kind of environmental protection alkalescence button formula battery, comprise positive electrode material, negative cover, negative material, O-ring seal, anodal shell, electrolyte and diaphragm paper, it is characterized in that: inboard last layer copper-nickel alloy or the copper alloy electroplated of battery cathode lid, negative material comprises pure zinc powder, and adding High Purity Hydrogen indium oxide and indium oxide as the corrosion inhibiter that reduces the zinc powder hydrogen-evolution overpotential, negative material also comprises thickener, zinc oxide etc.
Wherein, above-mentioned positive electrode material can be made up of high-purity electrolytic manganese dioxide, graphite, potassium permanganate, potassium hydroxide solution and acetylene black etc.
Above-mentioned electrolyte is made up of potassium hydroxide, zinc oxide, High Purity Hydrogen indium oxide, indium oxide, pure water etc.
The utility model is owing to adopted at inboard last layer copper-nickel alloy or the copper alloy electroplated of battery cathode lid, negative material is mainly by pure zinc powder, and add the High Purity Hydrogen indium oxide and indium oxide has replaced the version of mercury as the corrosion inhibiter that reduces the zinc powder hydrogen-evolution overpotential, produce gas when effectively having prevented zinc in the battery and other raw material or Metal Contact and expand, reduced the gassing rate of hydrogen anode, made alkaline button formula battery reach environmental requirement.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
