The Industrial Design Of The Zinc-air Battery-thermal Control、Fluid Control And Cyclic Regeneration

An ideal industrial system should be a system whose raw materials are reproducible and recyclable. In this study, a novel zinc-air battery which has much higher package efficiency was introduced. Meanwhile, the specific fluid mechanics problems including the rate of heat generation、the method of heat dissipasion of zinc-air battery and design principle of liquid flow zinc-air battery were investigated. The goal of our study is to improve the work condition of zinc-air battery and satisfy the need of industry development in the future.The content of this study includes elementary theory and engineering technology.Engineering technology study:1. Introducing the new structure design of the zinc-air battery—the zinc-air battery connected by pressure and circle zinc-air battery, and modify the parts of battery, on which we have obtained 7 utility patents (or utility model patent). This structure is free of welding and easy to dismounting, which improve the recycle rate and part independence of our battery.2. Introducing the application of zinc-air battery on electrical bicycle. In our novel "electric to electric transform" mode, the zinc-air battery is both assistant power source and charging source, which improve the battery life of electrical bicycle and will change the conventional charging mode.3. We obtained the electrolytic reduction method of superfine ZnO fabrication and explained the electrolytic reduction condition and attentions of zinc cake manufacture. The discharge power after mix electrolytic reduction and general Zn powder was improves 22%. This technology lay the foundation for the business development of recyclable zinc-air battery.Elementary theory study:4. We measured that the ratio between the quantity of heat and discharge capacity of a zinc-air battery is 1:2, the rate of heat production is about 8 W. Thus, we simulated the flow field and temperature field of the zinc-air battery in fluent software. The results can be applied on the searching for proper battery thermal output.5. By a large number of experiments and software analysis, we deduced the basic parameters of liquid flow zinc-air battery:flow velocity range, minimum flow, Zinc capacity of cell, the range of differential pressure of pipe, separation distance of electrodes, layout of pipe in cells, ect.
