Abstract
The utility model provides a mercury-free button battery which comprises a negative polar plane cover 1, a cathode zinc 2, an anode plate 5 and an anode shell 6. The outer surface and the internal bottom layer of the substrate of the electroplating plate of the negative polar plane cover 1 are nickel coating, and the internal surface is nickel or indium layer. The main material of the cathode zinc comprises mercury-free zinc powder and electro-hydraulic fluid, and the additives comprise indium oxide and indium hydroxide. The anode plate 5 is manganese plate, silver oxide plate or silver-manganese oxide plate, and the additives comprise nano-titanium oxide. The mercury-free button battery of the utility model protects environment, has good effect and low production cost and improves the using efficiency of the battery with low reject rate.
Description
Technical field
The utility model relates to a kind of button cell, relates to a kind of non-mercury button cell particularly.
Background technology
Non-mercury button cell is world today's hot issue, also is an industry difficult problem.The emphasis difficult point of non-mercury button cell is negative pole cover and negative zinc cream.
Selecting for use of negative pole cover material is a key link of non-mercury button cell.Tradition button cell cathode cover often adopts the copper-plated plating sheet of bottom in the nickel plating of substrate outer surface, and because of the different complex manufacturing technology that make of its substrate two sides institute plating, operability is not strong, and rouses end rate height with the button cell that this negative pole cover is made.
Negative zinc cream is made up of major ingredient and additive, and major ingredient is selected zinc powder and electric liquid usually for use, all contains mercury in the zinc powder at first, because zinc is very unsettled in the electrolyte aqueous solution, separates out hydrogen easily and causes self discharge, so add mercury usually in negative zinc cream.When adding mercury, mercury forms layer protective layer at zinc surface---and zinc amalgam, suppressed zinc and separate out hydrogen in electrolyte.But mercury can produce to a certain degree pollution to environment, so people begin to seek the substitute of mercury.Indium and barium can replacement for mercury, and initial many personages are towards this direction test, and current part personage can make non-mercury button cell, but effect is not satisfactory, shows the cost height, and rate of finished products is low.
On the other hand, the utilance of selecting for use and filling a prescription to anode of positive electrode also has certain influence.
Summary of the invention
The purpose of this utility model is to provide the non-mercury button cell that a kind of cost is low, rate of finished products is high, effective.
The utility model is achieved in that
A kind of non-mercury button cell comprises negative pole cover, negative zinc cream, positive plate and anode cover.Substrate outer surface and interior bottom that described negative pole cover is electroplated sheet are respectively nickel dam, and inner surface is layer of metal coating again.
The plating sheet of described negative pole cover can be that outer surface and interior bottom are nickel dam, and inner surface is tin or indium layer.
The substrate of the plating sheet of described negative pole cover can be iron plate or stainless steel substrates.
Described negative zinc cream major ingredient comprises mercury less zinc powder and electric liquid, comprises indium oxide and indium hydroxide in the additive.
Described positive plate can be manganese sheet, oxidation silver strip or silver manganese oxide sheet.In positive plate, replace potassium permanganate in the traditional handicraft as additive with nano-titanium oxide.Can effectively improve the battery inflatable, improve anodal utilance greatly.
Non-mercury button cell of the present utility model, its negative pole cover thickness of coating evenly, free of pinholes and density height, and it is simple to electroplate sheet manufacturing process; Adopt indium oxide and indium hydroxide to replace mercury in traditional button cell negative zinc cream or indium or barium both can reach the purpose of environmental protection in its negative zinc cream, can reduce cost again; In the positive plate, as additive, can effectively improve the battery inflatable, improve anodal utilance greatly with the potassium permanganate in the nano-titanium oxide replacement conventional batteries.Non-mercury button cell environmental protection of the present utility model, cost is low, and battery is respond well, and percent defective is low.
Description of drawings
Fig. 1 is the structural representation of non-mercury button cell.
Fig. 2 electroplates the coating structure schematic diagram of sheet for the negative pole cover.
Embodiment

Negative zinc cream 2 comprises major ingredient and additive, and major ingredient comprises mercury less zinc powder and electric liquid, comprises indium oxide and indium hydroxide in the additive.Negative pole cover 1 with negative zinc cream 2 is packed into and overlapped sealing ring 3 makes negative pole.
Positive electrode manganese dioxide, graphite powder, electric liquid and nano-titanium oxide mixed-forming are made positive plate 5, in the anode cover 6 of packing into, inject electrolyte and incorporate barrier film 4 into, reinstall negative pole, through seal mercury-free basic zinc/Mn button battery of the present utility model.
Embodiment 2
Press embodiment 1 described mercury-free basic zinc/Mn button battery, wherein negative pole cover 1 plating plate inner surface is the indium layer.
Embodiment 3
Press embodiment 1 described mercury-free basic zinc/Mn button battery, wherein the substrate 7 of negative pole cover 1 is a stainless steel substrates.
Embodiment 4
Replace manganese sheet in the above-mentioned technical process with the oxidation silver strip, can obtain mercury-free basic zinc of the present utility model/silver-colored button cell.
Embodiment 5
Replace manganese sheet in the above-mentioned technical process with the silver manganese oxide mixing tab, can obtain mercury-free basic zinc of the present utility model/silver-colored Mn button battery.
