Description
Technical field
The utility model relates to a kind of button zinc-air battery, relates to a kind of mercury-free basic button zinc-air battery that can prevent that bulging of battery own and electrolyte from revealing specifically.
Background technology
Zinc-air cell has specific energy height, stable, safe, cheap, the advantages of environment protection of discharge voltage because its particular structure, thereby is one of emphasis of electrochemical research field concern as novel energy storage device always.Advantages such as button zinc-air battery is little owing to its volume, capacity is big are widely used in such as portable type electronic products such as navigation light, electronic watch, calculator, hearing aids, electronic toys, have much the trend that substitutes other button cell products.
Alkalescence button zinc-air battery negative pole generally is made up of the zinc powder that is uniformly distributed with and indium, thickener furnishing calamine cream.In the zinc powder, generally need to add mercury element, the generation gas that reacts when preventing zinc and other raw materials or Metal Contact makes cell expansion, leakage.But, trend towards using the alkaline battery of no mercury on the market gradually for environmental protection.In order to suppress flatulence, usually zinc-air cell is electroplated, directly contact with zinc or other raw materials to hinder the negative electrode casing metal.At present the electrodeposited coating of negative electrode casing inner surface is adopted as materials such as tin or indium usually, but stores and the anti-leak performance still has and waits to improve.
Summary of the invention
The button zinc-air battery that the technical problem that the utility model will solve provides a kind of structure and manufacture craft is simple, can effectively prevent battery bulging and leakage.
For solving the problems of the technologies described above, the utility model technical scheme is following:
A kind of button zinc-air battery; Comprise negative electrode casing, insulated enclosure circle, negative zinc cream, barrier film, positive plate, ventilated membrane and anode cover; Be coated with two-layer electrodeposited coating on the inner surface of said negative electrode casing base material; Ground floor electronplate between the negative electrode casing base material inner surface and the second layer is nickel or tin, and thickness is 1～4 μ m; Second layer electronplate is a bismuth, thickness 0.2～10 μ m.
Manufacture craft is following: negative electrode casing is base material as the collector of negative pole with the steel band, earlier steel band is struck out basic configuration, i.e. the negative electrode casing of battery.At the plating inner surface ground floor electronplate nickel or the tin of negative electrode casing base material, re-plating second layer electronplate bismuth on the basis of ground floor electronplate then; Outer surface is general consistent with internal surface treatment method, and just the control of thickness of coating is accurate unlike the inner surface that kind; Place mould injection moulding sealing ring with electroplating good negative electrode casing.Positive plate and ventilated membrane place in the anode cover as the positive pole of battery, and the negative electrode active material calamine cream is contained in the negative electrode casing, between positive plate and negative zinc cream, barrier film are housed.With behind anode cover and the negative electrode casing fastening, on stamping machine, seal moulding at last with the special-purpose sealing mould.
The metal that electrodeposited coating uses can be single metal, can be the alloy of several kinds of metals also, but need heat treatment after considering alloy plating, and therefore the electroplating technology of single metal is simpler, has more advantage.
The button zinc-air battery that the utility model provides has following beneficial effect:
1, the composite deposite of electrotinning bismuth or nickel bismuth on the negative electrode casing inner surface can prevent effectively that the direct haptoreaction of calamine cream and negative electrode casing metal from producing gas, expanding, even electrolyte leakage.
2, the composite deposite of electrotinning bismuth or nickel bismuth on the negative electrode casing inner surface improves the decay resistance of negative electrode casing in alkaline solution, thereby has the function of anti-leakage.
3, the outermost bismuth metal coating of negative electrode casing inner surface can improve the overpotential of hydrogen evolution of calamine cream and coating contact-making surface, suppresses the generation of hydrogen, prevents the battery inflatable, thereby need not to add the mercury to severe environmental pollution in the calamine cream.
