Definitions
- the present invention relates to an electrolyte for an alkaline battery and an alkaline battery using the electrolyte.
- Alkali batteries that use an alkaline solution as an electrolyte are used as batteries that respond to such miniaturization of electronic devices.
- relatively inexpensive zinc or zinc alloy powder is used as a negative electrode active material because of its high hydrogen overvoltage.
- potassium hydroxide is used as the electrolyte in water.
- a gelled negative electrode obtained by mixing zinc or zinc alloy powder as a negative electrode active material with a gelling agent and an electrolytic solution is used.
- impurities are mixed into the zinc or zinc alloy powder used as the negative electrode active material after the battery is installed, from other members and through the route to the production. Similarly, impurities also elute in the electrolytic solution.
- an object of the present invention is to provide an electrolyte for an alkaline battery which suppresses the generation of hydrogen gas and prevents the occurrence of battery leakage, and an alkaline battery using the electrolyte. Disclosure of the invention
- the present inventors have found that the above object can be achieved by including a certain concentration of aluminum in the electrolytic solution.
- the present invention has been made based on the above findings, and provides an electrolyte for an alkaline battery containing aluminum and having an ion concentration of 5 to 20 Oppm.
- the present invention also provides an alkaline battery using the above electrolyte.
- FIG. 1 is a cross-sectional view showing an example of the alkaline battery of the present invention.
- the electrolytic solution for an alkaline battery of the present invention contains aluminum, and its ion concentration is 5 to 200 pt) m, preferably 10 to 15 Oppm. I If the on-concentration is less than 5 ppm, the generation of hydrogen gas cannot be suppressed and the occurrence of battery leakage cannot be prevented. As described above, the following means (1) to (3) are employed to make the electrolyte contain a predetermined concentration of aluminum.
- Aluminum is contained in the zinc alloy powder as the negative electrode active material, and the aluminum is eluted in the electrolytic solution. In this case, it is necessary to determine the aluminum content in the zinc alloy powder based on the aluminum elution amount. Thus, a predetermined concentration of aluminum can be contained in the electrolytic solution.
- Aluminum in the electrolyte exists in an ionized state or a salt state.
- the electrolytic solution of the present invention is obtained by dissolving zinc oxide in an aqueous solution of about 40% by weight of a hydroxide hydroxide to a saturated state.
- the alkaline battery of the present invention will be described.
- the alkaline battery of the present invention uses the above-mentioned electrolytic solution, and is otherwise the same as a conventional alkaline battery.
- 1 is a sectional view showing an example of the alkaline battery of the present invention.
- 1 is a positive electrode can
- 2 is a positive electrode
- 3 is a separator
- 4 is a negative electrode
- 5 is a negative electrode current collector
- 6 is a sealing cap
- 7 is a gasket
- 8 is a negative electrode terminal.
- the negative electrode 4 is zinc or zinc alloy powder as the negative electrode active material.
- the gelled negative electrode is formed by mixing the above-mentioned electrolytic solution containing a certain concentration of aluminum and aluminum with a gelling agent.
- the gelling agent used here polyvinyl alcohol, polyacrylate, carboxymethylcellulose, arginic acid and the like are used.
- a molten alloy was prepared so as to have a predetermined alloy composition, and was atomized to obtain a zinc alloy powder containing 0.013% by weight of bismuth and 0.050% by weight of indium.
- As an electrolytic solution a solution of a 40% by weight aqueous hydroxide water solution saturated with zinc oxide was used, and aluminum powder was added thereto so that the aluminum ion concentration became 50 ppm.
- gas characteristics and battery characteristics were evaluated. The gas properties were evaluated by immersing 10 g of the zinc alloy powder in 5 ml of the electrolytic solution and measuring the gas generation rate (/ il ZgZday) for 3 days at 45. The results are shown in Table 1 as raw gas.
- the zinc alloy powder was used as the negative electrode, and the alkaline manganese battery (JIS standard LR6 type) shown in Fig. 1 was constructed, a continuous discharge was performed with a discharge resistance of 1 ⁇ , and the cut-off (Cut) voltage was set at 0.2 V. After the discharged alkaline manganese battery was stored at a temperature of 60 for 3 days, the amount of gas generated was measured. Table 1 shows the amount of generated gas as the amount of gas included in the battery after 1 ⁇ constant resistance discharge.
- the battery characteristics were as follows: After storing an alkaline battery in JIS standard LR6 format at a temperature of 20 days for 7 days, a continuous discharge was performed with a discharge resistance of 1 ⁇ , and a discharge up to a voltage of 0.9 V was performed. It was evaluated by measuring the duration. The results are shown in Table 1. (Example 2)
- a molten alloy is prepared so as to have a predetermined alloy composition, and is atomized to contain 0.013% by weight of bismuth, 0.050% by weight of aluminum, and 0.008% by weight of aluminum.
