Abstract

In the General Formula 1, Ar denotes at least one selected from the group consisting of 1,1-binaphthalene, anthracene, triphenylene, tetraphenylene, and pyrene, and is optionally substituted with a substituent. The substituent of Ar is at least one selected from the group consisting of an OH group, a carbonyl group produced through oxidization of the OH group, an alkyl group containing 3 or less carbon atoms, a halogen atom, and an amino group. n denotes an integer in a range of from 2 through 8.

First claim

What is claimed is:

1. A secondary battery, comprising an electrode active material comprising:
an organic compound, which is at least one of a substituted anthracene and a compound represented by formula (1) below:
Ar—(OH) n   (1),

wherein:
Ar denotes at least one selected from the group consisting of 1,1-binaphthalene, triphenylene, tetraphenylene, and pyrene, Ar is optionally substituted with a substituent, the substituent of Ar is at least one selected from the group consisting of an OH group, a carbonyl group produced through oxidization of the OH group, an alkyl group containing 3 or less carbon atoms, a halogen atom, and an amino group;
n denotes an integer ranging from 2 to 8; and
the substituted anthracene is compound No. 23, 24, 25, 26, 27, 28, 29, 30, 31, 32 or 33:

2. The secondary battery according to claim 1 , wherein:
the secondary battery further comprises a cathode, an anode, and an electrolyte; and
at least one of an electrode active material for the cathode and an electrode active material for the anode comprises the organic compound.

3. The secondary battery according to claim 2 , wherein the electrode active material for the cathode comprises the organic compound.

4. The secondary battery according to claim 1 , wherein Ar is substituted with at least one selected from the group consisting of an OH group, a carbonyl group produced through oxidization of the OH group, and a halogen atom.

5. The secondary battery according to claim 1 , wherein Ar is substituted with at least one selected from the group consisting of a fluorine atom, a chlorine atom, and a bromine atom.

6. The secondary battery according to claim 1 , wherein Ar is at least one selected from the group consisting of substituted or unsubstituted 1,1-binaphthalene, substituted or unsubstituted anthracene, and substituted or unsubstituted triphenylene.

7. The secondary battery according to claim 1 , wherein n is an integer ranging from 2 to 6.

8. The secondary battery according to claim 1 , wherein the organic compound is compound No. 4, 24, or 34 below:

9. The secondary battery according to claim 1 , wherein the secondary battery is a lithium ion secondary battery.

10. A secondary battery, comprising a cathode, an anode and an electrolyte,
wherein:
the cathode has a cathode layer comprising a cathode active material, and the anode has an anode layer comprising an anode active material;
at least one of the cathode layer and the anode layer is a coating layer of a kneaded material obtained by mixing an electrode active material, a conductive aid and a binder;
the electrode active material that is mixed in the coating layer comprises an organic compound represented by formula (1) below as a main component:
Ar—(OH) n   (1),

wherein:
Ar denotes at least one selected from the group consisting of a substituted or unsubstituted 1,1-binaphthalene, a substituted or unsubstituted anthracene, and a substituted or unsubstituted triphenylene;
n denotes an integer ranging from 2 to 8.

11. The secondary battery according to claim 10 , wherein Ar is at least one selected from the group consisting of a substituted or unsubstituted 1,1-binaphthalene, an unsubstituted anthracene, and a substituted or unsubstituted triphenylene.
