The invention discloses a preparation method of a high-specific-energy zinc-silver battery. The preparation method comprises the following steps that step 1, material preparation: silver is selected as a positive pole piece, zinc serves as a negative pole piece, a potassium hydroxide water solution is used as an electrolyte, and a cellulose membrane is taken as a diaphragm; and step 2, formation:the raw materials are prepared into a zinc-silver battery, and the zinc-silver battery is placed into a formation tank for charging treatment for 40-70 hours; step 3, drying: the formed zinc-silver battery is dried; when the formation time reaches 2/3 of the total formation time, an alcohol solution is added into the electrolyte, wherein the mass ratio of the alcohol solution to the electrolyte is0.05 to 0.2, and the formation is continued. The formed zinc-silver battery is arranged in an organic glass shell to form a single battery, and the single battery is subjected to a discharge test under the condition of 30 DEG C. Compared with the prior art, the weight specific energy of the battery is improved by 5%-15%.

High-specific-energy zinc-silver battery and preparation method thereof

PURPOSE:To produce efficiently powder mold of small weight scatter especially thin mold by stamping of powder to be molded which is passed through sieves just before molding.

Molding method of powder

PURPOSE:To detect with non destruction a battery with an increased interval discharge through measurement of the open circuit voltage, by adding to the positive-electrode portion a bi-valent silver oxide of which the weight is not over 1% to the zinc weight of the negative-electrode portion CONSTITUTION:A bi-valent silver oxide of which the weight is not over 1% to the weight of the zinc in the negative electrode is formed in the positive electrode By charging the amount of electricity corresponding thereto, the battery voltage is increased to make possible the detection of the succeeding battery interval discharge with non destruction Further, after detection of the abnormal battery with an internal discharge, by aging, partial discharge processing, etc, it is possible to eliminate the shortcomings of high voltage That is, although since the positive electrode contains therein a bi-valent silver oxide, the open circuit voltage is high, the battery with interval discharge can be detected by measuring the open circuit voltage because the contact of the bi-valent silver oxide is very small and this bi-valent silver oxide is consumed according to the interval discharge if any, into silver oxide which results in that the voltage decreases in level By adding to the positive electrode portion the bi-valent silver oxide of which the weight is from 002% to 1% to the zinc weight in the negative electrode as mentioned above, the battery with a large internal discharge can be detected with non destruction through the measurement of the open circuit voltage

Silver oxide battery and manufacturing method therefor

PURPOSE:To produce a high capacity anode with a single stabilized discharge voltage and low internal resistance, by forming insulating film on part of the surface of an anode forming agent and a silver layer on the residual part. CONSTITUTION:A silver layer 7 is formed through vapor coating on the upper and lower sides of an anode forming agent 4, while an insulating Teflon film 8 is formed on the inner surface of an anode can 2 coming in touch with a side of the anode forming agent 4. Oxidation of the silver layer chemically forms an Ag2 layer on the surface of the anode forming agent and AgO inhibits generation of high electric potential to provide stabilized discharge potential.
