摘要： Active material for a negative electrode of a rechargeable zinc alkaline electrochemical cell is made with zinc metal particles coated with tin and/or lead. The zinc particles may be coated by adding lead and tin salts to a slurry containing zinc particles, a thickening agent and water. The remaining zinc electrode constituents such as zinc oxide (ZnO), bismuth oxide (Bi2O3), a dispersing agent, and a binding agent such as Teflon are then added. The resulting slurry/paste has a stable viscosity and is easy to work with during manufacture of the zinc electrode. Further, the zinc electrode is much less prone to gassing when cobalt is present in the electrolyte. Cells manufactured from electrodes produced in accordance with this invention exhibit much less hydrogen gassing, by as much as 60-80%, than conventional cells. The cycle life and shelf life of the cells is also enhanced, as the zinc conductive matrix remains intact and shelf discharge is reduced.
摘要翻译：可充电锌碱性电化学电池的负极的活性材料由涂覆有锡和/或铅的锌金属颗粒制成。可以通过向含有锌颗粒，增稠剂和水的浆料中加入铅和锡盐来涂覆锌颗粒。然后加入剩余的锌电极成分如氧化锌（ZnO），氧化铋（Bi 2 O 3），分散剂和粘结剂如特氟纶。所得到的浆料/糊料具有稳定的粘度，并且在锌电极的制造过程中易于加工。此外，当电解质中存在钴时，锌电极容易发生气体渗透。从根据本发明生产的电极制造的电池比常规电池表现出少得多的氢气，多达60-80％。电池的循环寿命和保质期也得到提高，因为锌导电基体保持完整，并且降低了放电。

摘要： A nickel-zinc battery cell is formed with a negative can, a positive cap, and a jelly roll of electrochemically active positive and negative materials within. The inner surface of the can is protected with an anticorrosive material that may be coated or plated onto the can. Good electrical contact between the jelly roll and the cap is achieved through folding the nickel substrate over to contact a positive current collection disk.

摘要： A high rate, alkaline nickel zinc cell (12) is structured as a bipolar cell having a current collector (22), with a positive nickel hydroxide electrode (14) on one side and a zinc negative electrode (46) on the other side. The current collector comprises a sheet copper substrate in contact with the negative electrode. A sheet nickel substrate (24) is laminated to the copper current collector, and is in contact with the positive electrode. The nickel hydroxide positive electrode is applied in a thin film to the respective face of the sheet nickel substrate. The zinc negative electrode comprises copper foam which is secured to the copper current collector at its edges, and is pasted. The copper foam is pressed so as to form a plurality of pockets (50) which face the copper current collector when assembled. Thus, access is provided to the negative electrode for oxygen generated at the positive electrode during overcharge conditions.

摘要： Active material for a positive electrode of a rechargeable alkaline electrochemical cell is made with nickel hydroxide particles or cobalt-coated nickel hydroxide particles treated with strongly oxidizing reagents such as alkali metal persulfate in alkaline solution. The active material also may be made with cobalt-coated nickel hydroxide particles having a high percentage of cobalt(III) on a surface or an average cobalt oxidation state of about 3 measured across the particles. The treated nickel hydroxide or cobalt-coated nickel hydroxide decreases the cobalt solubility in the alkaline electrolyte and increases the high-rate charge and discharge capability. The lower cobalt solubility decreases cobalt migration that can increase self discharge and lead to premature failure.
摘要翻译：可充电碱性电化学电池的正极的活性材料由氢氧化镍颗粒或用强氧化剂如碱金属过硫酸盐在碱性溶液中处理的钴包覆的氢氧化镍颗粒制成。活性材料也可以由在表面上具有高百分比的钴（III）的钴涂覆的氢氧化镍颗粒或在整个颗粒上测量的约3的平均钴氧化态约3制成。经处理的氢氧化镍或钴包覆的氢氧化镍降低了在碱性电解液中的钴溶解度，并提高了高速率的充放电能力。较低的钴溶解度降低了钴迁移，可以增加自放电并导致过早的失效。

摘要： A pasted positive nickel hydroxide electrode for use in battery cells (e.g., in nickel zinc cells, and nickel metal hydride cells) includes nickel hydroxide particles, a cobalt metal and/or cobalt compound and a sulfur-containing complexing agent capable of forming a complex with cobalt. The presence of the sulfur-containing complexing agent, such as dialkyldithiocarbamate (e.g., sodium diethyldithiocarbamate) improves lifetime and capacity utilization of the nickel electrode. The resulting pasted nickel hydroxide electrode includes a CoOOH conductive matrix after formation. The surface of the nickel hydroxide particles in the electrode is modified in some embodiments by providing a cobalt-containing coating onto the surface of the nickel hydroxide particles, followed by oxidation with a strong oxidizing agent. The complexing agent can be added before, after, or during the oxidation.
