    摘要: A rechargeable pencil battery has a hollow cylindrical positive electrode including nickel hydroxide; a gelled negative electrode comprising at least one of zinc and a zinc compound; a separator interposed between the hollow cylindrical positive electrode and the gelled negative electrode; and a negative electrode current collector inserted into the gelled negative electrode. Rechargeable batteries of the invention are capable of between about 50 and 1000 cycles from a fully charge state to a fully discharged state at a discharge rates of about 0.5 C or greater, in some embodiments about 1 C or greater. Batteries of the invention have a ratio of length to diameter of between about 1.5:1 and about 20:1, and therefore can be longer than typical commercially available batteries but also include batteries of commercial sizes e.g. AAAA, AAA, AA, C, D, sub-C and the like.

    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: 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.

The electrode is prepared by mixing zinc oxide with the chosen metallic oxide in an aqueous medium such as water or potassium hydroxide, stirring overnight, filtering and drying the mixture, optionally adding a further small amount of zinc oxide, optionally adding other metallic oxides, and adding hydroxy-ethyl cellulose, an oxide dispersant, and a binder. The aqueous paste os slurry thus formed is placed on a conductive substrate, drawn through a sizing gap, cut and dried, to form low cost pasted zinc oxide electrodes.

    摘要: A control system is designed or configured to control the state of charge of a battery or battery pack in a system containing a separate power source, which is separate from the battery or battery pack. In operation, the battery or battery pack is called upon to intermittently provide power for certain functions. The separate power source may be, for example, an AC electrical power source for a UPS or an engine of a vehicle such as a micro hybrid vehicle. The battery may be a nickel zinc aqueous battery. The control system may be designed or configured to implement one or more of the following functions: monitoring the state of charge of the battery or battery pack; directing rapid recharge of the battery or battery pack from the separate power source when the battery or battery pack is not performing its functions; and directing charge to fully charged level or a float charge level, which is different from the fully charged level, in response to operating conditions.
