锌 /空气电池锌膏阳极制备装置及制备锌膏阳极的方法 技术领域 Zinc/air battery zinc paste anode preparation device and method for preparing zinc paste anode
本发明涉及锌 /空气电池， 具体的说涉及锌 /空气电池锌膏阳的制备装 置； 本发明还涉及采用上述装置制备锌膏阳极的方法。 BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a zinc/air battery, and more particularly to a zinc/air battery zinc paste anode preparation apparatus; and to a method of preparing a zinc paste anode using the above apparatus.
背景技术 Background technique
锌 /空气电池是一种采用金属锌作为阳极燃料，空气中氧气作为氧化剂， 碱液作为电解质溶液的电化学反应装置。 我国金属锌储量丰富、 且价格低 廉， 因此锌 /空气电池在我国通讯电源、 野外应急电源、 照明电源及储备电 源等可移动电源的诸多领域具有广阔的应用前景。 锌 /空气电池具有能量密 度高、 安全性高、 反应物和产物无污染、 工作安静隐蔽性好、 金属燃料储 存、 运输、 携带安全方便且干态存储性好等特点， 其理论能量密度高达 The zinc/air battery is an electrochemical reaction device using metal zinc as an anode fuel, oxygen in the air as an oxidant, and alkali as an electrolyte solution. China's metal zinc reserves are abundant and low in price. Therefore, zinc/air batteries have broad application prospects in many fields of mobile power sources such as communication power sources, field emergency power supplies, lighting power supplies and reserve power sources. Zinc/air batteries are characterized by high energy density, high safety, no pollution of reactants and products, good work and concealment, safe storage and transportation of metal fuel, safe and convenient storage, and good dry storage.
1350Wh/kg。 锌 /空气电池电极反应和电池总反应分别为： 1350Wh/kg. The zinc/air battery electrode reaction and the total battery reaction are:
阳极反应： Zn+20H-→ZnO+H20+2e— -1.25V ( 1 ) 阴极反应： 1/202 + H20 + 2e-→20iT +0.401V (2) 电池总反应： Zn+l/202→ZnO +1.65V (3 ) 由上式可知， 锌 /空气电池在反应过程中消耗金属锌、 空气中的氧气， 生成氧化锌。 金属锌是锌 /空气电池的能量载体。 为提高锌的利用率和放电 电流密度， 锌 /空气电池常采用锌粉制备成锌膏阳极。 Anodic reaction: Zn+20H-→ZnO+H 2 0+2e— -1.25V ( 1 ) Cathodic reaction: 1/20 2 + H 2 0 + 2e-→20iT +0.401V (2) Total battery reaction: Zn+ l/20 2 → ZnO +1.65V (3 ) It can be seen from the above formula that the zinc/air battery consumes zinc in the metal and oxygen in the air during the reaction to form zinc oxide. Metallic zinc is the energy carrier for zinc/air batteries. In order to improve zinc utilization and discharge current density, zinc/air batteries are often prepared from zinc powder as zinc paste anodes.
锌膏阳极常用的制备方法包括电沉积法、 滚压法和模具法。 电沉积法 常用来制备银锌电池用锌电极， 但由于该方法能耗高、 产量低， 难以满足 锌 /空气电池的需求。 滚压法可实现锌电极的连续制备， 但该方法也存在锌 电极密度不均匀， 电极厚度不宜过大等缺点。 模具法是锌 /空气电池用锌电 极的常用制备方法， 具有工艺简单、 电极厚度可控等优点。 模具法常将锌 膏刮涂于模具内， 并将集流网压合在一起制成电极。 该方法存在以下问题： Common preparation methods for zinc paste anodes include electrodeposition, rolling, and mold methods. Electrodeposition is often used to prepare zinc electrodes for silver-zinc batteries, but due to the high energy consumption and low yield of this method, it is difficult to meet the demand of zinc/air batteries. The rolling method can realize the continuous preparation of the zinc electrode, but the method also has the disadvantages that the density of the zinc electrode is not uniform and the thickness of the electrode is not too large. The mold method is a common preparation method for zinc electrodes for zinc/air batteries, and has the advantages of simple process and controllable electrode thickness. The mold method often applies a zinc paste to a mold, and presses the current collecting grid together to form an electrode. This method has the following problems:
( 1 ) 刮涂锌膏前， 需对每片电极的用锌量进行称量， 费时费力；(1) Before the zinc paste is applied, it is necessary to weigh the amount of zinc used for each electrode, which is time consuming and laborious;
(2) 刮涂锌膏过程电极均匀性难以控制； (2) The uniformity of the electrode during the process of scraping the zinc paste is difficult to control;
(3 ) 锌膏阳极批量制备过程中的一致性难以控制， 且生产能力有限。 发明内容 (3) The consistency of the zinc paste anode batch preparation process is difficult to control, and the production capacity is limited. Summary of the invention
