Definitions

  • the present invention relates to a manganese dioxide cathode for rechargeable alkaline manganese dioxide cells with improved overcharge properties, more particularly to catalysts added to the conventional manganese dioxide cathode material which substantially improve the overcharge properties of the cell.
  • the oxygen overcharge principle is well know n from the nickel-cadmium batteries.
  • the imbalance of the electrode capacities is essential, in order to assure that the cathode reaches the fully charged state first. This is achieved by there being still CdO left in the anode when the nickel oxide is starting to evolve oxygen gas.
  • the oxygen then travels to the anode and recombines with the metallic cadmium.
  • nickel oxide -- hydrogen cells the liberated ox y g en reacts with the hy drogen gas in a catalytic reaction supported by the surface of the fuel cell type anode and forms water. Due to the fact that this is a closed cycle in a gas-tight sealed cell, the overall electrolyte concentration does not change and the only product of the overcharge reaction is heat.
  • the object of the invention is to provide a manganese dioxide cathode material which has improved overcharge properties, which enables the use of chargers with operational voltage above 1.75 V, in which the formation of manganates is effectively prevented during overcharge, whereby there will be a smaller decrease in capacity durin g cycle life, and in w hich the end of charge state can be monitored more easily.
  • the amount of said catalysts lies between 1 and 5 mass%.
  • nickel oxide in an amount of at most 5 mass% , preferably 1 to 3 mass%, in combination with either one of vanadium pentoxide ( 2O5) or nickel cobaltite (NiO.C ⁇ 2 ⁇ 3 ) is preferable, due to improved potential characteristics in the overcharge region.
  • the substantially improved overcharge properties of manganese dioxide cathodes that are achieved according to this invention can be utilized in all types of rechargeable cells using manganese dioxide as the cathode electrode. It must be understood, however, that in the overcharge mode, oxy gen gas is developed and the cell design should provide a reaction (recombination) for this oxygen gas. This constitutes no problems for a number of cell types, while in other cells specific measures should be introduced for this purpose.
  • the overcharge potential curves will be changed in such a way that a well-detectable voltage increase is obtained in the overcharge period which can be used to trigger an end of charge signal before irreversible cathode reactions could start.
  • This behavior enables the use of conventional or at least less precise charger circuits, since there will be no need to inhibit the increase of the charging voltage above 1.75 V.

After dry mixin g these co mponents, the p o w der obtained w as immersed in benzine (boiling range 80-110 ° C) and homogenized for 3-4 hours. Subsequently the excess benzine was separated be filtration and the solid residue was kneaded until the paste had a suitable consistency for the following rolling process . Rolling started with a sheet of about 4mm thickness and was continued step by step until a final thickness of 0.8 to 0.9 mm was achieved. In the last step the foil was rolled on a nickel screen used as a current collector. Finally, the product was dried at 40 ° C for 12 hours. Circular electrodes with a diameter of 50.2 mm were cut out, contacted with a nickel wire and used as working electrodes in the test cell.

Abstract

Cathode en bioxyde de manganèse pour piles alcalines rechargeables en bioxyde de manganèse présentant des caractéristiques améliorées de surcharge. Elle comporte, en plus des constituants traditionnels, au maximum 10 % en masse de catalyseur, ce qui rend st÷chiométriquement équivalent au courant de charge le dégagement d'oxygène pendant la surcharge et cela, sans qu'il ne se produise de réaction secondaire avec le manganate. Les catalyseurs appropriés (seuls ou combinés) font partie du groupe constitué de CoAl2O4 (= CoO.Al2O3), ZnCo2O4 (= ZnO.Co2O3), NiCo2O4 (= NiO.Co2O3), V2O5, NiO, Co3O4, NiO.2CoO.
