  • Patent number: 10833310
    Abstract: A secondary battery includes: a battery element; a casing which accommodates the battery element; a positive electrode terminal and a negative electrode terminal provided to the casing and electrically connected to the battery element; and a cut-off portion which switches from a grounded state in which the casing and one terminal of the positive electrode terminal and the negative electrode terminal have an identical potential, to a cut-off state in which the casing and the one terminal are electrically cut off. The one terminal has a facing portion which faces the casing, and the cut-off portion is arranged between the facing portion and the casing. When the casing is externally short-circuited, the cut-off portion switches from the grounded state to the cut-off state by being deformed by heat generated as a short-circuit current flows.

  • Patent number: 10749168
    Abstract: An electrochemical cell or battery uses iron gall ink as an electrolyte. In some examples, mold, bacteria, or yeast are allowed to grow on the electrolyte. The ink is made by combining tannic or gallic acid from a material such as dehydrated tea with a metal or transition metal sulfate, such as iron sulfate, potassium sulfate, or manganese sulfate. Urea, a metal or transition metal salt, and glycerin can also be added to the electrolyte to assist in the ion-producing reaction. One example includes electrodes made from iron and graphite, and an electrolyte of iron-gall or iron-tannate ink. Another example uses a manganese based ink. Aluminum, potassium, or sodium tannate ink, urea, and graphite can be used to make a metal-air cell, in which the cell is open to the air. The ink can be used as a charge transport in a redox-flow electrochemical cell. Yet another example utilizes Bauxite residue, a waste product of aluminum manufacture.
