Description
Technical Field
The present invention belongs to the technology of replacing mercury-containing paper pulp in the existing battery with mercury-free paper pulp containing novel polymer solid electrolyte in the production of dry battery.
Background
The paper pulp plays a role in isolating positive and negative electrode materials in the battery, so that the electrolyte can penetrate through the paper pulp to absorb a certain amount of electrolyte and keep the normal discharge of the battery. The conventional coated paper generally comprises base paper, adhesive, liquid retention agent, paste, additive and the like. The binder, the liquid retaining agent and the paste are all water-absorbent polymer materials. Polyvinyl alcohol (PVA) is typically used as the binder and barrier material. Sodium carboxymethyl cellulose (CMC) and Polyacrylamide (PAM) are used as liquid retention agents, and crosslinked starch and crosslinked etherified starch are used as paste materials. However, these high molecular materials can conduct electricity only by absorbing electrolyte solution, and do not perform the above-mentioned function when the amount of the high molecular materials is small, and increase the resistance of the coated paper when the amount of the high molecular materials is large, thereby reducing the current and the capacity of the battery. Secondly, the gelatinization of the cross-linked starch can be fully realized only when the concentration of the electrolyte is high and the pH value is low, so that the electrolyte is absorbed, and the ionic conductivity is improved; it does not swell sufficiently at low electrolyte concentrations and high pH values, and therefore can only be used in "high power" P-type cells. It does not sufficiently perform its function in "high capacity" C-type batteries. Thirdly, the pulp layer paper prepared by the existing pulp has low liquid absorption speed, small swelling degree and poor liquid retention, and has strict requirements on base paper, otherwise, the pulp layer paper cannot be made into high-quality pulp layer paper. Fourthly, after the organic mercury-substitute corrosion inhibitor is added into the coated paper to prepare mercury-free coated paper, the resistance of the coated paper is increased, and the current and the capacity are reduced.
Disclosure of Invention
The invention aims to provide mercury-free pulp laminated paper of a zinc-manganese battery containing a polymer solid electrolyte, so as to achieve the aims of improving the electrical property of the zinc-manganese battery and realizing mercury-free operation.
The object of the present invention is achieved based on the following idea. The invention adds the novel polymer solid electrolyte into the pulp of the pulp layer paper, reduces the internal resistance of the pulp layer paper, accelerates the liquid absorption speed, increases the swelling degree and improves the liquid retention to realize the purposes of improving the electrical property of the zinc-manganese dry battery and realizing mercury-free operation. The mercury-free zinc-manganese battery coated paper is characterized in that the slurry of the coated paper consists of a high polymer solid electrolyte and an organic mercury-substituted corrosion inhibitor, wherein the high polymer solid electrolyte is prepared from coordination ionic liquid and PVA, PAM, PEG and starch, and the coordination ionic liquid is prepared from urea, thiourea, zinc chloride and ammonium chloride by heating and melting according to a certain proportion; wherein:
the composition of the coordination ionic liquid is expressed by mass percent as follows: urea, thiourea, zinc chloride and ammonium chloride, wherein the weight ratio of urea to thiourea to zinc chloride to ammonium chloride is 65-75 percent to 12-20 percent to 7-12 percent to 0-10 percent;
the composition of the polymer solid electrolyte is expressed by mass percent as follows: coordination ionic liquid, PVA, PAM, PEG =50-70%, 0.5-3%, 1-5%, 1-10% and 20-40%;
the pulp slurry of the pulp layer contains 0.2 to 0.5 percent of organic mercury-substituting corrosion inhibitor and the balance of polymer solid electrolyte.
In the invention, the starch is a mixture of cross-linked starch and etherified starch, and the mixing ratio of the cross-linked starch to the etherified starch is expressed as follows according to mass ratio: 3-24: 7.
The organic mercury corrosion inhibitor in the pulp slurry of the mercury-free zinc-manganese dry battery is prepared according to the specification of Chinese patent ZL02123804.9, commonly used are cephalosporins and phytates (sodium phytate and the like), and the organic mercury corrosion inhibitor consists of two components A and B, wherein A is a heterocyclic compound and has the structure shown as follows:
wherein M is Na or K;
R 1 is-CH 2 -or-CH 2 -CH 2 -；
R 2 is-CH 3 or-CH 2 CH 3 ；
B is a cyclic compound containing six phosphorus atoms, and the molecular formula is as follows:
the preparation process of the invention is as follows:
firstly, heating, melting and cooling urea, thiourea, zinc chloride and ammonium chloride to prepare the coordination ionic liquid. And secondly, adding a certain amount of water into the coordination ionic liquid, polyvinyl alcohol (PVA), polyethanol (PEG), polyacrylamide (PAM) and modified starch to prepare polymer gel slurry, then adding 0.1-0.3% of organic mercury-substitute corrosion inhibitor to prepare mercury-free slurry, coating the mercury-free slurry on base paper according to the thickness required by the battery, drying, and preparing the polymer solid electrolyte mercury-free slurry layer paper which can be used for preparing the mercury-free zinc-manganese dry battery.
The mercury-free pulp laminated paper has the following advantages: the film part in the coated paper is a polymer solid electrolyte formed by ionic liquid and polymer, so the coated paper has different properties from the film part of the common coated paper. First, the conductivity increases. The coordination ionic liquid prepared from urea, thiourea, zinc chloride and ammonium chloride is a green solvent and is formed by coordinating the urea and thiourea to zinc ions and ammonium ions of the zinc chloride and the ammonium chloride. The coordination ionic liquid can swell the macromolecule to generate macromolecule gel. The room temperature conductivity of the polymer gel can reach 10 -1 s/cm, 3-4 orders of magnitude higher than that of common polymer gel, and the conductivity is doubled when the polymer gel film absorbs the electrolyte in the anode cell, so that the internal resistance of the coated paper is far lower than that of the common coated paper. The short-circuit current of the battery increases, and the battery capacity increases. Secondly, the viscosity is increased, and PVA, PAM, modified starch and complex ion liquid are addedThe formed gel has greatly increased viscosity, and the viscosity of common slurry can be reached by using a small amount of high polymer. When the polymer gel absorbs water and swells, the melt-expansion volume ratio can be increased to more than 5 times, which is more beneficial to a pulp layerThe tight combination of paper and zinc can. Third, it is known that crosslinked starch can be gelatinized only under a high concentration of an electrolyte and under a strong acidic condition. After the cross-linked starch is gelatinized, a large amount of electrolyte is absorbed, and the ionic conductivity is improved. The paste degree is small in low-concentration and slightly acidic electrolyte, the absorption electrolyte is less, and the ionic conductivity is poor. The new cross-linked starch gel has strong absorption capacity to electrolyte due to containing ionic liquid, can be fully gelatinized under slightly acidic condition, can be used in a high-power P-type battery, and can also fully play a role in a high-capacity C-type battery. Fourthly, the polymer gel has high liquid absorption speed and good liquid retention property, and can improve the electrical performance of the battery. The polymer gel contains coordination ionic liquid, belongs to ionic property, so the liquid absorption speed is very high, the liquid absorption amount is large, the liquid retention is good, the discharge dynamic performance of the battery is good, and the defects that the liquid absorption rate of the pulp layer paper is low, the liquid absorption speed is low and water bubbles are generated beside the pulp layer paper in the wet weather of the C-type battery are overcome. And the defect that the load voltage suddenly drops and rises again in the discharge process of the paperboard battery is also avoided. Fifthly, the synergistic corrosion inhibition effect of the polymer gel and the organic mercury-substituting corrosion inhibitor is strong. In order to manufacture mercury-free batteries, organic mercury corrosion inhibitors are often added, and are adsorbed on the surface of zinc, so that the separation of hydrogen and the discharge of the batteries are prevented, and the discharge resistance of the batteries is increased. The polymer gel contains micromolecular corrosion inhibitors such as urea, thiourea and the like, and contains polyethylene glycol chain molecule adsorption corrosion inhibitors, so that the micromolecules can supplement parts which cannot be adsorbed by macromolecules during storage to enhance the corrosion inhibition effect. During discharging, the micromolecules are desorbed quickly, the discharging resistance of the battery cannot be increased, and the synergy of the macromolecule corrosion inhibitor and the micromolecule corrosion inhibitor plays a good corrosion inhibition role and reduces the discharging internal resistance.
Because the pulp layer paper prepared by the pulp has the advantages, the requirement standard for the base paper is relatively reduced, the defects of the base paper are compensated, and the high-quality pulp layer paper can be manufactured by using the low-quality base paper.
