    Abstract: 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.

    Abstract translation: 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。

    Abstract: 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 0.5C or greater, in some embodiments about 1C 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.
