Description
Technical field
The utility model relates to field of batteries, especially relates to a kind of without the unleaded alkali button battery of mercury, comprises without mercury unleaded zinc-manganese button cell with without the unleaded silver oxide button cell of mercury.
Background technology
The production technology of existing mercury-free alkali button battery, be adopt plating, chemical plating and strip method directly at battery cathode iron covering integral surface plating indium or zinc-plated or plating indium alloy or zinc-plated alloy, prepare mercury-free alkali button battery negative current collector.Be included in battery cathode iron covering integral surface to carry out electroplating or electroless plating indium or zinc-plated or plating indium alloy or zinc-plated alloy, then the outer surface coating decoating liquid of battery cathode lid removed.Due to the self structure reason of battery cathode iron covering, cause covering power and covering power all poor, easily cause the thickness of coating of negative cover uneven, not fine and close, poor adhesive force, there is pore, even dark recess does not have the defects such as coating, and strip be easy to cause battery cathode lid inside coating be damaged, cause negative zinc cream and negative cover iron substrate contact generation chemical reaction liberation of hydrogen, cause battery inflatable, leakage such as even to be exploded at the safety problem, in addition, these methods have waste water, waste gas, heavy metals emission, particularly there are the heavy metals emissions such as a large amount of chromium ions in strip process, severe contamination and the wasting of resources can be caused to environment.Therefore, be badly in need of a kind of not only environmental protection but also the technical scheme of existing mercury-free alkali button battery potential safety hazard can be overcome.
Utility model content
The utility model provides a kind of without the unleaded alkali button battery of mercury, efficiently solve prior art directly in the defect that the plating of negative pole iron covering integral surface or chemically plating exist for negative current collector, and strip causes coating damaged inside battery cathode lid, cause negative zinc cream and negative cover iron substrate contact generation chemical reaction liberation of hydrogen, the safety problem such as cause that battery inflatable, leakage are even exploded.
The utility model, without the need to strip, efficiently solves existing technology and there is plurality of heavy metal discharge, can cause the problem of severe contamination and the wasting of resources to environment.
For achieving the above object, the utility model is achieved in that
A kind of without the unleaded alkali button battery of mercury, comprise negative cover, negative current collector, O-ring seal, negative zinc cream, barrier film, positive electrode and anode cover, described negative current collector is arranged on the inner side of negative cover, the inner shape of the outer shape of negative current collector, size and negative cover, measure-alike, the outer surface of negative current collector and the inner surface of negative cover are combined closely, and the inner surface of negative current collector contacts with negative zinc cream.This negative current collector adopts the good aluminium of electric conductivity or copper or aluminium alloy or alcu alloy film, on aluminium or copper or aluminium alloy or alcu alloy film surface, is coated with indium or tin or indium alloy or tin alloy coat, makes through punching press.The utility model negative current collector effectively prevents self-discharge of battery liberation of hydrogen, effectively prevent negative zinc cream simultaneously and contacts with negative cover iron chemical reaction liberation of hydrogen occurs.
Compared with prior art, the utility model is provided with a negative current collector between battery cathode lid and negative zinc cream, solve prior art directly at negative pole iron covering integral surface plating indium or zinc-plated or plating indium alloy or zinc-plated alloy, again cathode cover exterior face coating is carried out the method for strip, easily occur coating poor plating and strip be easy to cause battery cathode lid inside coating be damaged, cause negative zinc cream and negative cover iron substrate contact generation chemical reaction liberation of hydrogen, cause battery inflatable, leakage such as even to be exploded at the safety problem, the utility model negative current collector effectively prevents self-discharge of battery liberation of hydrogen, effectively prevent negative zinc cream to contact with negative cover iron chemical reaction liberation of hydrogen occurs simultaneously, overcome the deficiency that prior art exists, improve security performance and the shelf characteric of battery.The utility model, without the need to strip, efficiently solves existing technology and there is plurality of heavy metal discharge, can cause the problem of severe contamination and the wasting of resources, be conducive to environmental protection to environment.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
