Abstract
Official abstract text for this publication.
An alkaline dry cell includes a positive electrode, a negative electrode, and an alkaline electrolyte solution. The negative electrode includes a terephthalic acid compound and a negative electrode active material containing zinc. The terephthalic acid compound is terephthalic acid having an electron-withdrawing substituent or a salt thereof. The electron-withdrawing substituent is, for example, at least one selected from the group consisting of Br, F, and Cl. The terephthalic acid compound preferably includes terephthalic acid having one electron-withdrawing substituent or a salt thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. An alkaline dry cell comprising: a positive electrode, a negative electrode, and an alkaline electrolyte solution, wherein the negative electrode includes a terephthalic acid compound and a negative electrode active material containing zinc, and the terephthalic acid compound is terephthalic acid having an electron-withdrawing substituent or a salt thereof. 2. The alkaline dry cell according to claim 1 , wherein the electron-withdrawing substituent is at least one selected from the group consisting of Br, F, and Cl. 3. The alkaline dry cell according to claim 1 , wherein the terephthalic acid compound includes terephthalic acid having one electron-withdrawing substituent or a salt thereof. 4. The alkaline dry cell according to claim 1 , wherein the terephthalic acid compound includes 2-bromoterephthalic acid or a salt thereof. 5. The alkaline dry cell according to claim 1 , wherein an amount of the terephthalic acid compound is 1000 ppm to 10000 ppm relative to a mass of the negative electrode active material. 6. The alkaline dry cell according to claim 1 , wherein the negative electrode contains a halide ion and a terephthalate ion.
