A nickel–zinc battery, abbreviated NiZn, is a type of rechargeable battery similar to NiMH batteries, but with a higher voltage of 1.6 V. Larger nickel–zinc battery systems have been known for over 100 years. Since 2000, development of a stabilized zinc electrode system has made this technology viable and competitive with other commercially available rechargeable battery systems. Unlike some other technologies, trickle charging is not recommended.

Methods of manufacturing a rechargeable power cell are described. Methods include providing a slurry or paste of negative electrode materials having low toxicity and including dispersants to prevent the agglomeration of particles that may adversely affect the performance of power cells. The methods utilize semi-permeable sheets to separate the electrodes and minimize formation of dendrites; and further provide electrode specific electrolyte to achieve efficient electrochemistry and to further discourage dendritic growth in the cell. The negative electrode materials may be comprised of zinc and zinc compounds. Zinc and zinc compounds are notably less toxic than the cadmium used in NiCad batteries. The described methods may utilize some production techniques employed in existing NiCad production lines. Thus, the methods described will find particular use in an already well-defined and mature manufacturing base.

Pasted zinc electrode for rechargeable nickel-zinc batteries
ActiveUS20100291439A1High viscositySimple working processFinal product manufacturePrimary cellsZinc metalSlurry
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.

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.

Rechargeable and replaceable zinc cartridges have been used as the components of nickel-zinc batteries. The battery life of a zinc battery is extended by periodic replacing of the zinc anodes at about 10% of the battery cost. Flat modules that include several cells interconnected with channels are used as basic elements of a flat battery. A home wall battery is produced by assembling the modules using rotational joints. The performance of the zinc current collectors is improved by deposition of Zn—Cu—Bi alloy. Zinc composition is formulated using additives of polyphenylenediamines and zirconium hollow fibers.

Method for making solid polymer electrolyte and uses thereof
A method for preparing a composite alkaline solid polymer electrolyte from polyvinyl alcohol (PVA) polymer, potassium hydroxide and water is disclosed. Said polymer electrolyte is reinforced with glass-fiber cloth to increase its mechanical strength, thermal stability and electrochemical stability. The glass fiber cloth matrix provides a stable interface between the cathode and the anode to reduce the short circuit problem when the battery discharges at high rate. The processes for polymer electrolyte are controlled by molecular weight of PVA polymer, the sequence of feeding in reactants, the weight proportions of reactants, the reaction time, the reaction temperature, and the drying conditions, i.e. under the specified conditions of relative humidity (RH), temperature and drying time. The resulting electrolyte exhibits ionic conductivity of 0.15 S / cm or better at room temperature and has high mechanical intensity and good electrochemical stability. This polymer electrolyte can replace the conventional PP non-woven fabric separator in primary and secondary alkaline batteries, metal-air battery, nickel-metal hydride battery, nickel-cadmium battery, nickel-zinc battery, fuel cells and capacitors. This composite PVA-GF polymer electrolyte can be used in thin-film alkaline battery system (thickness <4 mm) to reduce the weight and thickness of battery, while significantly increasing the energy and power densities of the battery. It offers another opportunity for making thin and lightweight batteries to be used in future 3C electronic products.
