Description
Technical field
The present invention relates to a kind of zinc-silver cell, the particularly silver oxide electrode of zinc-silver cell.
Background technology
The advantages such as zinc-silver oxide cell has discharging voltage balance, specific energy is big, specific power is high and safe and reliable, are applied to one
In a little specific uses higher to battery performance requirements.But zinc-silver oxide cell there will be the high popin of electric discharge in discharge process
Platform, main cause is the effect of silver oxide pole plate, when have impact on the stability of voltage, especially high temperature and low discharging current, puts
The high popin platform of electricity can be the most obvious.The existence of high-order platform is fatal to the use of some precision instruments, manage to eliminate electricity
Pressure Gao Bo, keeps the stability of voltage.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of zinc-silver cell possessing stabilized electrodes voltage, possesses
Stable silver oxide pole plate, it is possible to eliminate the high-order platform produced in zinc-silver oxide cell discharge process.
The present invention is achieved in that a kind of zinc-silver cell possessing stabilized electrodes voltage, including silver oxide pole plate,
Silver oxide constitutes battery core as anelectrode with barrier film, negative electrode, and battery core and electrolyte are contained in lucite housing.
Described silver oxide pole plate is suppressed by collector and silver oxide and is formed, and carries out surface process by chemical reagent.Institute
Stating surface Physicochemical reagent is ascorbic acid (vitamin C) solution, and the mass percent concentration of ascorbic acid solution is 0.5%
～1.5%.The collocation method of ascorbic acid solution is: add the ascorbic acid powder that mass percent is 0.5%～1.5% in water
End, and stir, can be used as silver oxide polar board surface reagent treatment.
Described electrolyte be mass percent be the KOH aqueous solution of 25%～45%.
The positive and negative pole plate related in the present invention is attached to collector by active substance by the method for compacting and coating respectively
Upper formation.
In the present invention, positive pole silver oxide pole plate is immersed in the mixed solution being made up of ascorbic acid and water, solution temperature 25
DEG C, take out after its immersion treatment 15s, and it is carried out water flushing process.
The positive pole silver oxide pole plate processed by chemical reagent and negative pole zincode plate are by barrier film compositing monomer battery.
Use the zinc-silver oxide cell that in the present invention, silver oxide electrode assembles, coordinate electrolyte of the present invention, at the ring of 55 DEG C
Carrying out low discharging current work in border, voltage high-order platform is effectively eliminated.
Compared with prior art, effect is obvious, simple to operate for the present invention, the chemical reagent environmental protection soaked.
Detailed description of the invention
A kind of zinc-silver cell possessing stabilized electrodes voltage, zinc-silver oxide cell mainly by negative collector bar, positive collector bar, every
Film, negative electrode, electrolyte, anelectrode, lucite housing etc. are constituted.
Anelectrode, negative electrode can use sintering silver electrode technique to be prepared from being coated with cream zinc electrode.Anelectrode and negative electrode
Can not directly contact, separate with barrier film, and use laminar to constitute pole group.The positive terminal of pole group is drawn by positive collector bar
Going out, negative pole end is drawn by negative collector bar.
Ascorbic acid powder and water are configured to the solution that mass percent is 0.5%～1.5%, and positive plate passes through Vitamin C
Acid solution carries out immersion treatment, solution temperature 25 DEG C, takes out after its immersion treatment 15s, wash afterwards, dry stand-by.
Barrier film can be three cellulose acetate membrane.The height anelectrode to be exceeded of barrier film and negative electrode.
Electrolyte be mass percent be the potassium hydroxide aqueous solution of 25%～45%, the filling of electrolyte to load pole group
Carry out after lucite housing.
Cell passes through discharge test, can effectively eliminate the high-order platform under high temperature, small area analysis.
In battery-pack exterior casing, battery pile both positive and negative polarity draws wire and gas generator harness contact corresponding with connector
Welding, finally seals with lid.
