Abstract
An active material contains at least one element M selected from the group consisting of nickel, cobalt, manganese, and lithium and an element X different from the element M. The element X comprises at least one member selected from metals of groups 2 and 15 in the second period, metals of groups 3, 11, and 13 to 16 in the fourth period, metals of groups 1 to 3, 7 to 13, and 15 to 17 in the fifth period, metals of groups 1 to 3 and 7 to 17 in the sixth period, and metals of groups 1 to 17 in the seventh period of the periodic table.

An active material comprising:
- at least one element M selected from the group consisting of nickel, cobalt, manganese, and lithium;
- and
- an element X different from the element M, and
- the element X comprising at least one member selected from metals of groups 2 and 15 in the second period of the periodic table, metals of groups 3, 11, and 13 to 16 in the fourth period of the periodic table, metals of groups 1 to 3, 7 to 13, and 15 to 17 in the fifth period of the periodic table, metals of groups 1 to 3 and 7 to 17 in the sixth period of the periodic table, and metals of groups 1 to 17 in the seventh period of the periodic table.
A method for producing a recycled active material comprising:
- recovering an element M from a battery having an active material A containing the element M, the element M being at least one member selected from the group consisting of nickel, cobalt, manganese, and lithium, and
- producing an active material B which is the same or different from the active material A using the recovered element M,
- the active material A further containing at least one element X selected from metals of groups 2 and 15 in the second period of the periodic table, metals of groups 3, 11, and 13 to 16 in the fourth period of the periodic table, metals of groups 1 to 3, 7 to 13, and 15 to 17 in the fifth period of the periodic table, metals of groups 1 to 3 and 7 to 17 in the sixth period of the periodic table, and metals of groups 1 to 17 in the seventh period of the periodic table.
A method for tracing a valuable element recovered from a battery, comprising,
- when an active material B is produced using an element M recovered from a battery having an active material A containing the element M, the active materials A and B being the same or different from each other, and the element M being at least one member selected from the group consisting of nickel, cobalt, manganese, and lithium,
- using, as the active material A, an active material further containing at least one element X selected from metals of groups 2 and 15 in the second period of the periodic table, metals of groups 3, 11, and 13 to 16 in the fourth period of the periodic table, metals of groups 1 to 3, 7 to 13, and 15 to 17 in the fifth period of the periodic table, metals of groups 1 to 3 and 7 to 17 in the sixth period of the periodic table, and metals of groups 1 to 17 in the seventh period of the periodic table, and
- tracing the element M recovered from a battery having the active material B on the basis of the type and/or amount of the element X contained in the active material B.
A method for tracing a valuable element recovered from a battery, comprising,
- when an active material B is produced using an element M recovered from a battery containing an active material A containing the element M, the active materials A and B being the same or different from each other, and the element M being at least one member selected from the group consisting of nickel, cobalt, manganese, and lithium
- using, as the active material A, an active material further containing an element X that is neither contained in a natural ore as a source of the element M nor involved in battery reaction of a battery containing the active material B and
- tracing the element M recovered from the battery containing the active material B on the basis of the type and/or amount of the element X contained in the active material B.
A tracer compound for tracing a valuable element recovered from a battery, comprising at least one element X selected from metals of groups 2 and 15 in the second period of the periodic table, metals of groups 3, 11, and 13 to 16 in the fourth period of the periodic table, metals of groups 1 to 3, 7 to 13, and 15 to 17 in the fifth period of the periodic table, metals of groups 1 to 3 and 7 to 17 in the sixth period of the periodic table, and metals of groups 1 to 17 in the seventh period of the periodic table,
- the tracer compound being adapted to be added to an active material A containing at least one element M selected from the group consisting of nickel, cobalt, manganese, and lithium when an active material B is produced using the element M recovered from a battery containing the active material A, the active materials A and B being the same or different from each other, and
- the tracer compound being used to trace the element M recovered from a battery containing the active material B.
A tracer compound for tracing a valuable element recovered from a battery, comprising an element X,
- the tracer compound being adapted to be added to an active material A containing at least one element M selected from the group consisting of nickel, cobalt, manganese, and lithium when an active material B is produced using the element M recovered from a battery containing the active material A,
- the active materials A and B being the same or different from each other,
- the tracer compound being used to trace the element M recovered from a battery containing the active material B, and
- the element X being neither contained in a natural ore as a source of the element M nor involved in battery reaction of a battery containing the active material B.
