Zinc-silver oxide battery is a practical battery with high specific energy and high specific power developed in 1940s. Its development can be traced back to two centuries ago. Zinc-silver battery packs are introduced to the world at a voltage of 65,438+0,800 volts. The first complete alkaline zinc-silver oxide primary battery was described in Clarke's patent 65,438+0,883, and zinc oxidation was first proposed in Dun and Hassla-cher's patent 65,438+0,887. However, it was not until 194 1 year that H. Andr6 of France proposed to use a semi-permeable membrane (such as cellophane) as the diaphragm, and a practical zinc-silver battery was realized. Yard-ney designed and manufactured a practical rechargeable zinc-silver battery in 1950s. Later, the development of missiles and spacecraft promoted the development of zinc-silver batteries. In the production of zinc-silver batteries in the 1990s, the United States consumed about 40 tons of silver every year, and it is estimated that the annual consumption of silver in the world is above 100t t ... Zinc-silver batteries have maintained a prosperous trend in special applications such as airplanes, submarines (Figure 3- 1), buoys, missiles, spacecraft and ground electronic instruments.
China's zinc-silver battery has also developed with the development of missiles and space flight. It has been developed since the late 1950s and applied to missiles designed by China since the mid-1960s. At present, China has developed various specifications of primary batteries, storage batteries and automatically activated zinc-silver reserve batteries that can be put into use instantly, and has formed a certain scale of production capacity, which can meet the needs of various weapons and satellites such as missiles and torpedoes. In recent years, it has met the needs of civil use, and also produced button-type zinc-silver batteries and open-type batteries in batches, meeting the needs of watches and photographic lighting.
