Description

A kind of negative pole of alkaline dry battery and application thereof
Technical field
The present invention relates to a kind of alkaline dry battery, particularly relate to a kind of negative pole and application thereof of alkaline dry battery, belong to cell art.
In the present invention, the meaning of following expression formula is:
PAA: polyacrylic acid sodium salt
PA: polyacrylic acid powder
Background technology
Alkaline battery is the most successful high capacity type dry cell, is also one of battery of current most cost performance.Alkaline battery take manganese dioxide as positive pole, and zinc is negative pole, and negative pole zinc is also changed over granular by sheet, increase the response area of negative pole, and potassium hydroxide is electrolyte.So electrical property is greatly improved, the alkaline battery of general equal model be the capacity of common batteries and the 3-7 of discharge time doubly, both cryogenic properties gap is larger.Alkaline battery is more suitable for big current continuous discharge and requires the electricity consumption occasion of high operating voltage, is specially adapted to camera, photoflash lamp, shaver, electronic toy, CD player, high-power remote controller, wireless mouse, keyboard etc.
But easily layering such as the active material zinc powder of the negative pole of alkaline dry battery of the prior art and electrolyte, other additives etc., sedimentation, affect the carrying out of negative reaction, thus affect the discharge performance of alkaline dry battery.
In addition, easily there is the phenomenon of leakage in alkaline dry battery in adverse circumstances or under long term storage, because electrolyte is the mordant alkaline matter potassium hydroxide of band, has spread effect to eyes, respiratory tract and skin.And, electrolyte also can attack metal, destroy electronic component, the electrolyte that therefore battery spills also can destroy and use the product, particularly electronic product of this battery.
About solution negative electrode of alkaline dry cell active material zinc powder and electrolyte, the easily layering such as other additives, the problem of sedimentation, have been reported in prior art, as Chinese invention patent (publication number: CN102760894A) discloses a kind of alkaline dry battery and alkaline dry battery anode mixture pellet, the negative pole simultaneously also disclosing this alkaline dry battery comprises Zinc alloy powder and alkaline electrolyte, relative to the Zinc alloy powder of 100 weight portions, in alkaline electrolyte, the parts by weight of each component are: cross-linking type polyacrylic acid: 1.25 weight portions, cross linked sodium polyacrylate: 0.2 weight portion, indium oxide: 0.04 weight portion, electrolyte liquid: 53 weight portions, pure water: 3 weight portions.Wherein, cross-linking type polyacrylic acid in alkaline electrolyte and cross linked sodium polyacrylate all play gelatification, the two makes alkaline electrolyte be gel jointly, although the phenomenon of zinc powder and electrolyte, other additive hierarchical, sedimentation can be alleviated, but, not clearly, still have greatly improved effect space; And this patent fails to improve the leak resistance of alkaline dry battery, and due to cathode additive agent kind more, also can bring impurity element into, affect the performance of alkaline dry battery.
Summary of the invention
The object of the invention is for the above-mentioned problems in the prior art, propose and a kind ofly can ensure that cell discharge performance is stablized and promotes the negative pole of the alkaline dry battery of the leak resistance of battery.
