Abstract
The utility model relates to a mercury-free alkaline button cell with a negative electrode alloy layer, wherein an indium tin alloy layer covers the inner surface of a metal negative electrode cover, and negative electrode zinc cream consisting of uniformly distributed zinc powder, metal indium, bismuth and aluminum powder is arranged between the negative electrode cover and a diaphragm; a manganese sheet is arranged between the diaphragm and the anode shell. The utility model has the advantages that: the indium tin alloy layer on the inner surface of the cathode cover isolates the direct contact of the cathode zinc paste and the cathode sheet metal, and prevents the expansion of zinc caused by the direct contact with the cathode cover metal, so that mercury which is used for preventing gas expansion and seriously polluting the environment does not need to be added into the battery; indium, bismuth, aluminum and other metal elements which are in line with environmental protection and no toxicity are added into the cathode zinc paste to replace toxic mercury elements, so that the hydrogen evolution overpotential of the cathode zinc surface can be improved, the generation of hydrogen is inhibited, the leakage resistance and the electrical property of the battery are improved, and the environmental protection requirement of no mercury is met.
Description
Technical field
The utility model relates to a kind of button cell, particularly relates to a kind of mercury-free alkali button battery that covers the band negative pole alloy-layer of indium stannum alloy layer at metal negative cover inner surface.
Background technology
At present general Alkaline Zinc/manganese button cell because of built-in " zinc " this raw material, must add mercury element, when preventing " zinc " with other raw materials or Metal Contact, produces gas and expands.But, tend to adopt the Alkaline Zinc/manganese cell of " not mercurous " on the market gradually along with environmental consciousness strengthens." AAA " type Alkaline Zinc/the manganese cell volume is bigger because of " AA " reaches, and has the space to hold the expansion that produces because of gas.But, because the volume ratio of " button type " Alkaline Zinc/manganese cell is less, in battery, can not there be vacant position to hold the expansion that gas causes again, so " button type " battery now still needs to add mercury, in order to avoid expand, make the cell shapes torsional deformation because of " zinc " produces gas with other raw materials or Metal Contact.Therefore, for environmental protection requirement, be badly in need of a kind of not mercurous button cell at present.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of mercury-free alkali button battery that covers the band negative pole alloy-layer of indium stannum alloy layer at metal negative cover inner surface.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of mercury-free alkali button battery with the negative pole alloy-layer, comprise negative cover, negative zinc cream, positive plate and anodal housing, between negative cover and anodal housing, barrier film is housed, and configuration O-ring seal, make negative cover and anodal housing interference fit, anodal housing closing in seal bead; Cover the indium stannum alloy layer at metal negative cover inner surface, the negative zinc cream of being made up of equally distributed zinc powder and indium metal, bismuth and aluminium powder is arranged between negative cover and the barrier film; Be provided with positive plate between barrier film and the anodal housing, described positive plate is the manganese sheet.
The beneficial effects of the utility model are:
1) the indium stannum alloy layer that covers on the negative cover inner surface has been isolated negative zinc cream and has been contacted with the direct of negative plate metal, prevents the expansion that " zinc " is produced when directly contacting with the negative cover metal.Like this, need not in the battery to add again that gas expands but the mercury of serious environment pollution reaches the environmental requirement of no mercury in order to prevent to produce.
2) on the raw material of traditional negative zinc cream and prescription, leave out mercury, adding indium, bismuth, aluminium etc. meet the metallic element of environment-protecting asepsis, replace poisonous mercury element, can improve negative pole zinc surface overpotential of hydrogen evolution, suppress the generation of hydrogen, improve battery leak resistance and electrical property.
Description of drawings
The utility model structural representation that Fig. 1 is.
Fig. 2 is the structural representation of the negative cover of inner surface plating indium stannum alloy layer.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Embodiment: a kind of mercury-free alkali button battery with the negative pole alloy-layer, comprise negative cover 1, negative zinc cream 3, positive plate 6 and anodal housing 7, between negative cover 1 and anodal housing 7, barrier film 5 is housed, and configuration O-ring seal 4, make negative cover 1 and anodal housing 7 interference fit, anodal housing 7 closing in seal bead.Inner surface in stainless steel negative cover 1 covers the indium stannum alloy layer, and the negative zinc cream of being made up of equally distributed zinc powder and indium metal, bismuth and aluminium powder 3 is arranged between negative cover 1 and the barrier film 5; Be provided with manganese sheet 6 between barrier film 5 and the anodal housing 7.
Entrust national testing agency that 23A of the present utility model and 625A button cell are tested with atomic absorption spectrum, the result is as follows:
Table 1
Table 1 shows: the mercury content of 23A of the present utility model and 625A button cell, cadmium content, lead content all are significantly less than the permissible value of 98/101/EEC about the standard code of button cell.
As follows with inductively coupled plasma spectrometer-mass spectrometer to the result that alkaline button cell of the present utility model detects:
Table 2
| Test parameters | Result (mg/kg) (ppm) |
| Lead content | *32 |
| Cadmium content | Less than 2 |
| Mercury content | *0.5 |
Above result of the test proves that the mercury content of button cell of the present utility model has only 0.5mg/kg (ppm), less than environmental protection standard setting 1mg/kg (1ppm), belongs to the mercury-free battery classification.
Claims (2)
1. mercury-free alkali button battery with the negative pole alloy-layer, comprise negative cover, negative zinc cream, positive plate and anodal housing, between negative cover and anodal housing, barrier film is housed, and configuration O-ring seal, make negative cover and anodal housing interference fit, anodal housing closing in seal bead, it is characterized in that: the inner surface of metal negative cover (1) covers indium stannum alloy layer (2), and the negative zinc cream of being made up of equally distributed zinc powder and indium metal, bismuth and aluminium powder (3) is arranged between negative cover (1) and the barrier film (5); Be provided with positive plate (6) between barrier film (5) and the anodal housing (7).
2. a kind of mercury-free alkali button battery with the negative pole alloy-layer according to claim 1 is characterized in that: described positive plate (6) is the manganese sheet.
