Definitions
- the present invention relates to an alkaline battery including zinc as a negative electrode active material, nickel oxyhydroxide and manganese dioxide as a positive electrode active material, and an alkaline aqueous solution as an electrolytic solution.
- Alkaline batteries typified by alkaline manganese dry batteries, are widely used as power sources for various devices because they are versatile and inexpensive. With the spread of digital devices in recent years, the load power of devices using these batteries is gradually increasing. Therefore, a battery having excellent high load discharge performance has been demanded.
- Patent document 1 corresponding to this demand proposes mixing nickel oxyhydroxide with the positive electrode mixture to obtain excellent high-load discharge characteristics.
- an alkaline battery (nickel manganese battery) containing such nickel oxyhydroxide in a positive electrode mixture has been put into practical use and has come into widespread use.
- Nickel oxyhydroxide used in nickel manganese batteries is obtained by oxidizing spherical nickel hydroxide used in alkaline storage batteries (Patent Document 2) with an oxidizing agent such as an aqueous sodium hypochlorite solution. Is generally obtained by The spherical nickel hydroxide used as a raw material is a / 3 type with a large bulk density (tap density). By subjecting it to oxidation treatment, ⁇ -type spherical nickel oxyhydroxide is obtained.
- Patent Document 3 proposes the use of zinc alloy powder containing a small amount of aluminum, bismuth and indium as the negative electrode active material in order to improve the corrosion resistance of the negative electrode.
- Patent Document 4 proposes that the corrosion resistance is further improved by setting the bismuth content in the zinc alloy to 0.05 to 0.05% by weight.
- Patent Document 5 states that the fine powder ratio of 200 mesh (75 m) or less is 5% by weight or more. I suggest using zinc powder.

- a nickel manganese battery is excellent in high load characteristics as compared with a normal alkaline manganese dry battery. However, its characteristics are not sufficient. This is evident, for example, when the following discharge tests are performed on a conventional alkaline manganese battery and nickel manganese battery, assuming a digital still camera. That is, first, a battery (1 cell) was discharged at a constant power of 650 mW for 28 seconds in an atmosphere of 20 ° C., and then discharged for 2 seconds at a constant power of 1500 mW. Repeat this operation as one cycle, and measure the number of cycles until the lower limit voltage of 1500m W pulse discharge reaches 1.05V. The measurement results are shown in Figs. The positive electrode potential and negative electrode potential shown in FIG. 2 and FIG.
- a hole is provided in a part of the positive electrode case of each battery, and the positive and negative electrodes are connected via a salt bridge. It is obtained by measuring in a liquid junction with the mercury / mercury oxide reference electrode outside the battery.
- nickel manganese cells (Fig. 3) have improved pulse discharge characteristics. This is probably because nickel manganese batteries also have potential flatness with a high positive electrode potential. That is, it can be seen that the nickel manganese battery has better high-load Norse discharge characteristics than the conventional alkaline manganese battery.
- an object of the present invention is to provide an alkaline battery that suppresses the polarization of the negative electrode unique to the nickel manganese battery and has excellent high-load Nos discharge characteristics.
- the present invention includes a positive electrode, a negative electrode, a separator, and an alkaline electrolyte.
- the positive electrode includes nickel oxyhydroxide and manganese dioxide as a positive electrode active material, and the negative electrode is a negative electrode.
- the electrode contains at least zinc as an active material, and the content of indium in the negative electrode active material is
- the present invention relates to an alkaline battery that is 0.02% by weight or less.
- the negative electrode active material in the present invention contains at least zinc or an alloy of zinc and indium (zinc alloy). Therefore, the negative electrode active material may contain other elements (including aluminum, bismuth, and calcium, which will be described later) as long as the effects of the present invention are not impaired. Use alloys with elements, or alloys of zinc, indium and other elements.
- the configuration of the alkaline battery of the present invention it is possible to suppress the polarization of the negative electrode unique to the nickel manganese battery at the end of the pulse discharge cycle. As a result, it is possible to greatly improve the noise discharge characteristics of the alkaline battery when the load is high.
