【摘要】：化学电源是通过化学反应方法将化学能转变为电能的装置,有多种类型,例如镉镍电池、镍氢电池、铝氧化银电池、热电池、锂离子电池、锌银电池等,锌银电池是化学电源的一个种类,其应用范围广,实用性强,优点较多。锌银电池的优点是重量比能量和体积比能量及放电比功率要较优于某些其它电池,同时还具有安全可靠性好、放电过程中电压精度高及可以适应大电流放电等特点。目前大量武器装备如火箭、导弹、鱼雷、无人机等都在使用锌银电池,同时民用产品如深潜器、水下机器人及大量通讯设备也都在使用锌银电池。随着武器系统向小型化、轻型化、精确制导、远程攻击、多弹头、灵活机动等方向的发展,对配套的锌银电池也提出了更高的要求。要求锌银电池前期小电流密度放电消除高坪阶电压,同时兼顾放电后期大电流密度放电电压符合要求。本文首先对消除锌银电池前期小电流密度放电高坪阶电压的方法进行了研究,通过对不同化成制度及化成后高温烘干法、化成后使用卤素离子溶液浸泡法和放入高温环境中进行加热的热分解法三种锌银电池氧化银电极生产方法生产的氧化银电极,配以锌电极制造成单体,并对单体进行放电,对放电数据进行分析。通过分析,寻找最佳的锌银电池消除高坪阶电压的方法,同时不影响电极的其它性能,例如结构强度等性能。其次,本文在确定消除高坪阶电压的方法后,对不同方法消除高坪阶电压制作的电极,制作成单体电池,先进行前期小电流密度放电,在放电中后期加以大电流密度脉冲放电,同时考察大电流密度脉冲放电电压。对放电电压数据进行分析,找到既满足放电前期消除高坪阶电压,又满足放电中后期大电流密度脉冲放电电压较高的电极生产方法。本文的研究成果,作为锌银电池设计的参考,可为锌银电池设计创新提供帮助。
[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.
