Description
Technical field:
The utility model relates to the battery technology field, specifically is meant a kind of mercury-free basic zinc/Mn button battery, mercury-free basic zinc/silver-colored button cell.
Background technology:
The mercury-free alkaline manganese button cell belongs to can not filling property primary cell, belongs to the spatter property non-renewable energy resources.The battery manufacturing has had the history in more than 200 year.But all the time,, can prevent effectively that battery gas from rising by problems such as leakage because the particularity of alkaline manganese button cell must adopt the important source material of extremely toxic substance mercury as the negative pole inhibition.Because of mercury can have a strong impact on the nervous system of animal, its toxicity is very big, enter human body after, can destroy the basic function and the metabolism of cell, destroy the function of detoxification of liver cell, suppress nutriment and enter cell, and cause ion emigrated cell film, cause meronecrosis, renal failure; Long term exposure can have a strong impact on people's brain in the mercury environment of high concentration, the harm such as fetus in kidney and the growth.
At present, strict regulation has all been made to the mercury content in the battery by various countries.Federal law " containing mercury cell and chargeable battery management method " as U.S.'s promulgation in 1996, the 98/101/EC instruction (Battery Directive) of European Union and " about in electronic electric equipment, banning use of some harmful substance instruction " (being the RoHS instruction) of passing through on February 13rd, 2003, and December in 1997,9 ministries and commissions such as the former Commission of Light Industry sent " about the regulation of mercury content in the limit battery product " unites notice etc., had all proposed Mercury in Battery content is not more than the requirement of total cell weight 0.0001%.
Because the particularity of button cell structure, big as zinc negative pole inhibition area, no air chamber, no explosionproof hole etc., it is mercuryless to be a great problem of global battery industry always, comprise developed country, all contain the mercury of higher amount in the batteries such as the button alkali manganese of most (more than 95%), silver oxide, because some application does not still have the product of replacement at present.Thereby the mercury content of control in the alkaline manganese button cell is in recent years, the common target of pursuing of countries in the world battery industry, realize button cell mercuryless be the requirement of button cell technological progress, also be pressing for of environmental protection.Our company passes through effort for many years, has developed the mercury-free alkaline manganese button cell.
Summary of the invention:
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of nontoxic, anti-battery drum spirit to rise and leakage, cost is low, rate of finished products is high mercury-free basic buckled battery.
For achieving the above object, the technical scheme that the utility model provides is: mercury-free basic buckled battery, include negative cover, negative pole zinc powder, sealing ring, positive plate and anode cover, the substrate of negative cover simultaneously is electroplate with nickel dam, and another side is nickel coating, copper layer, ashbury metal or indium alloy layer successively from inside to outside.
The end of the body bottom of described sealing ring extends upward the formation bulge loop, and the madial wall of the madial wall of this bulge loop and sealing ring body and interior diapire form groove, and groove and negative cover bottom match.
Described substrate is a kind of in iron plate or the stainless steel substrates.
Include indium oxide and indium hydroxide in the negative pole zinc powder.
Described positive plate is a kind of in manganese sheet, oxidation silver strip or the silver manganese oxide sheet.
Described anode cover adopts iron plate to make substrate, and two-sided nickel plating.
In sum, non-mercury button cell of the present utility model, its negative cover is taked nickel plating on web-like iron plate or stainless steel substrates surface, copper coating therein again, and at zinc-plated alloy of copper face or indium alloy, last punch forming can be guaranteed that thickness of coating is uniform and stable and prevent that chemical material from polluting; Adding indium oxide or indium hydroxide replace the mercury in traditional button cell cathode zinc powder in the negative pole zinc powder, can realize the mercuryless of button cell; The ring structure that adopts can cut off contacting of zinc powder and coating that punching press destroys, and prevents the generation that bulging spirit rises and leaks; The mode of taking sealing ring to cross the tunnel is carried out upper shield, has fundamentally solved the problem of battery drain.Non-mercury button cell of the present utility model has been realized mercuryless, and production cost is low, good leak-proof effect, and fraction defective is low.

Fig. 1 is the structural representation of non-mercury button cell.
Fig. 2 is the coating structure schematic diagram of negative cover.
Fig. 3 is the ring structure cutaway view.
Embodiment:
The non-mercury button cell of present embodiment includes negative cover 1, negative pole zinc powder 2, sealing ring 3, positive plate 5 and anode cover 6, and the substrate of negative cover 8 one sides are electroplate with nickel dam 7, and another side is nickel coating 9, copper layer 10, ashbury metal or indium alloy layer 11 successively from inside to outside.The end of the body bottom 31 of described sealing ring extends upward and forms bulge loop 36, and the madial wall 32 of this bulge loop forms groove 37 with the madial wall 34 of sealing ring body and interior diapire 35, and groove 7 matches with the negative cover bottom.The substrate 8 of above-mentioned negative cover can be selected a kind of in iron plate or the stainless steel substrates for use; Include indium oxide and indium hydroxide in the negative pole zinc powder 2; Positive plate 5 is selected a kind of in manganese sheet, oxidation silver strip or the silver manganese oxide sheet for use; Anode cover 6 adopts iron plate to make substrate, and two-sided nickel plating.
The structure of negative cover and material is a key link of non-mercury button cell performance quality in the utility model.At present, a lot of producers take sheet metal is made negative cover basically, at its electroplating nickel on surface or copper, then, plate layer of metal indium or tin again, because the empty unsteadiness of the dew of indium and tin, generally before or after the production battery, need to adopt indium alloy or the ashbury metal layer eccysis of chemical method with outer surface; Complex manufacturing technology, operability are not strong, and corrode interior surface easily, cause battery drum spirit to rise.And present embodiment is taked the metal steel band with web-like, continuity is electroplated, earlier at its plating nickel on surface, and one side copper facing therein again, strike out negative cover at last at zinc-plated alloy of copper coatings or indium alloy, and with the one side of alloy plating as the one side that contacts with the battery cathode zinc powder.Can improve the stability of product and prevent and pollute.
Because negative cover is in stamping forming process, occur easily the negative cover madial wall pull easily coating between the topic, mercury less zinc powder is as long as contact iron plate basic unit or nickel coating, and battery will be easy to occur the drum spirit and rise and leakage phenomenon, and this just needs idea be avoided the zinc powder contact to pull coating.
Another emphasis that the utility model is implemented is to change perpendicular type sealing ring of the prior art into the fluted body sealing ring, compare with the sealing ring shape of generally using, has better operability, and avoided assembling back electrolyte between negative cover and sealing ring, to leak, the sealing property of battery there is very desirable effect.During making, the method of the sealing ring covering cathode cover of being taked is to be the tunnel of 12-10% glue fully by glue content with sealing ring, negative cover is pressed in the sealing ring that dips in full glue again, through 50-60 ℃ temperature baking 30-180 minute, the sealing ring 3 that adopts nylon 66 to make is fully shunk, negative cover 1 is fully contacted with sealing ring 3, can play the effect of sealing fully, effectively prevent battery leakage.
