[Abstract]:Chemical power supply is a device that converts chemical energy into electric energy by chemical reaction. There are many kinds of devices, such as nickel cadmium battery, nickel hydrogen battery, aluminum oxide silver battery, thermal battery, lithium ion battery, zinc silver battery, etc.Zinc-silver battery is a kind of chemical power supply, which has wide application range, strong practicability and many advantages.The advantages of Zn-Ag battery are that the weight specific energy, volume specific energy and discharge specific power are better than some other batteries. At the same time, the Zn-Ag battery has the advantages of good safety and reliability, high voltage precision during discharge and can adapt to large current discharge.At present, a large number of weapons such as rockets, missiles, torpedoes, drones and so on are using zinc and silver batteries, while civilian products such as deep submersible, underwater vehicles and a large number of communications equipment are also using zinc and silver batteries.With the development of weapon system in the direction of miniaturization, lightness, precision guidance, long-range attack, multi-warhead, flexible mobility and so on, higher requirements are put forward for the matching zinc-silver battery.The low current density discharge in the early stage of zinc silver battery is required to eliminate the high level voltage, and the high current density discharge voltage at the later stage of discharge meets the requirements.In this paper, the method of eliminating the high voltage of low current density discharge in the early stage of zinc silver battery is studied.The silver oxide electrode produced by the three methods of producing silver oxide electrode of zinc-silver battery was prepared by immersing in halogen ion solution and heating in high temperature environment. The silver oxide electrode was prepared with zinc electrode, and the monomer was discharged.The discharge data are analyzed.Through the analysis, we find the best method to eliminate the high voltage of Zn-Ag battery without affecting other properties of the electrode, such as structure strength and so on.Secondly, after determining the method of eliminating the high level voltage, the electrode made by different methods to eliminate the high level voltage is made into a single cell, and the early discharge with low current density is carried out first, and the high current density pulse discharge is carried out in the middle and late stage of discharge.At the same time, the pulse discharge voltage with high current density is investigated.Based on the analysis of the discharge voltage data, the electrode production method is found, which can not only eliminate the high plateau voltage in the early stage of discharge, but also meet the high voltage of pulse discharge with high current density in the middle and late stage of discharge.The research results of this paper can be used as a reference for the design of zinc-silver batteries and can provide help for the innovation of zinc-silver batteries design.
