Provided is a material capable of further extending the life of a cell including a zinc species as a negative electrode active material. The present invention relates to an anion conducting membrane formed using an anion conducting membrane-forming material, the anion conducting membrane-forming material including a conjugated diene based polymer and/or a (meth)acrylic based polymer, and a compound containing at least one element selected from Groups I to XVII of the periodic table, the anion conducting membrane having a cross-section in which a ratio of a combined area of particles of the compound containing at least one element selected from Groups I to XVII of the periodic table to a combined area of the components of the anion conducting membrane-forming material other than the compound (particles of the compound/components of the anion conducting membrane-forming material other than the compound) is 70/30 to 30/70.

Anion conducting membrane

The present invention provides an electrode which is a zinc anode or an electrode of any other type, and ensures good durability and sufficiently high ion conductivity, and sufficiently improves the cell performance when used in a cell, and also provides its precursor. The present invention relates to an electrode which includes a current collector and an active material layer containing an active material, and further includes a specific anion conducting material or a specific solid electrolyte.

Electrode precursor, electrode, and cell

The present invention aims to provide an anion conducting material having excellent anion conductivity and durability, which can be suitably used as a separator, an electrolyte, or an electrode protecting agent of an alkaline cell, for example. The present invention also aims to provide a cell including a cell component containing the anion conducting material. The present invention provides an anion conducting material containing a polymer and a compound containing at least one element selected from Groups 1 to 17 of the periodic table.

Anion conducting material and cell

On producing a purified borazine compound, a borazine compound is filtrated under an atmospheric condition of a water content of not higher than 2000 volume ppm. Or, on filling a borazine compound into a container, the above described borazine compound is filled into the above described container under an atmospheric condition of a water content of not higher than 2000 volume ppm. Or, as a container for preservation for preserving a borazine compound, a container for preserving a borazine compound, which has withstanding pressure of not lower than 0.1 MPa, is used.
