Abstract
Official abstract text for this publication.
According to one aspect of the present invention, a nanocomposite cathode electrode is manufactured by mixing a cathode active material, a conductive material, and a binder and curing a resultant mixture, wherein the cathode active material may include a first mixture of a p-type organic compound and an n-type organic compound, or a second mixture of the p-type organic compound and metal powder.
First claim
Opening claim text (preview).
What is claimed is: 1 . A nanocomposite cathode electrode comprising a cathode active material, a conductive material, and a binder, wherein the cathode active material comprises a p-type organic compound and an n-type organic compound. 2 . The nanocomposite cathode electrode of claim 1 , wherein the p-type organic compound comprises a phenazine derivative. 3 . The nanocomposite cathode electrode of claim 1 , wherein the p-type organic compound comprises 5,10-dihydro 5,10-dimethylphenazine (DMPZ). 4 . The nanocomposite cathode electrode of claim 3 , wherein the n-type organic compound is selected to have a molecular weight greater than that of the p-type organic compound. 5 . The nanocomposite cathode electrode of claim 4 , wherein the molecular weight of the n-type organic compound is 300 g/mol or more. 6 . The nanocomposite cathode electrode of claim 3 , wherein the n-type organic compound comprises perylenetetracarboxylic dianhydride (PTCDA), 3,4,9,10-perylenetetracarboxylic diimide (PTCDI), or flavanthrone (FVT). 7 . The nanocomposite cathode electrode of claim 1 , wherein the p-type organic compound comprises 5,10-dihydro 5,10-dimethylphenazine (DMPZ), the n-type organic compound comprises PTCDA, and in the cathode active material, the DMPZ is present in an amount of 70% or more by weight and less than 80% by weight, and the PTCDA is present in an amount of 20% or more by weight and less than 30% by weight. 8 . A method of manufacturing a nanocomposite cathode electrode, comprising: forming a mixture by mixing a cathode active material, a conductive material, and a binder; and curing the mixture, wherein the cathode active material comprises a p-type organic compound and an n-type organic compound. 9 . The method of claim 8 , wherein the p-type organic compound comprises 5,10-dihydro 5,10-dimethylphenazine (DMPZ). 10 . The method of claim 9 , wherein the n-type organic compound is selected to have a molecular weight greater than that of the p-type organic compound. 11 . The method of claim 9 , wherein the n-type organic compound comprises perylenetetracarboxylic dianhydride (PTCDA), 3,4,9,10-perylenetetracarboxylic diimide (PTCDI), or flavanthrone (FVT). 12 . The method of claim 8 , wherein the cathode active material is formed by cryo-mixing the p-type organic compound and the n-type organic compound. 13 . The method of claim 8 , wherein, in the cathode active material, particles of the n-type organic compound are mixed in a form attached to particles of the p-type organic compound. 14 . A secondary battery comprising the nanocomposite cathode electrode according to claim 1 .
