。If these batteries are accidentally swallowed, the gastric juices are hydrochloric and acidic, resulting in a discharge state.Also, due to the voltage of the battery, electrolytic corrosion of the battery container, which also serves as the positive terminal, progresses, causing holes in the container. It may open and the contents may leak out.
If the aqueous alkaline solution used as the electrolyte is not diluted and adheres to the mucous membranes of the stomach or intestines while remaining highly concentrated, there is a risk that the mucous membranes of the stomach or intestines will be attacked and holes may form.

However, the conventional product gradually eluted from the force near the negative electrode as time passed, and only the nickel plating layer remained, and after 144 hours, the plate It is no longer possible to hold the positive and negative poles, and the positive and negative poles are separated.

1, but IN corrosion occurred in streaks or spots in the direction of the threads of the battery container, and a hole opened in the internal hole, causing the concentrated alkaline electrolyte solution to leak out and lowering the potassium concentration. It was increasing. This contact situation is called intergranular corrosion.
18-87. It can be seen that Ti-+ is produced by the crystal warp between Ti-containing carbon and Or in the steel.
Alternatively, by adding Nb, all the carbon contained therein can be changed into stable carbides such as TiC or NbC.
:S, (-) Crystal grains are less likely to be formed and the corrosion resistance of the battery container is improved.
