Abstract
Official abstract text for this publication.
Provided is an electrode including a current collector and an active material layer. The active material layer includes an active material, a film including silicone, a conductive additive, and a binder. The active material is in the form of a particle. The film including silicone covers at least part of the active material.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for manufacturing an electrode, comprising: forming a mixed liquid of an active material, silicone, and a first solvent; forming an active material with a film thereon by spraying the mixed liquid from a nozzle and evaporating the first solvent; forming a paste including the active material with the film thereon, a conductive additive, a binder, and a second solvent; and forming an active material layer by applying the paste to a current collector and evaporating the second solvent. 2 . The method for manufacturing an electrode, according to claim 1 , wherein the active material includes at least one of graphite, silicon, and silicon monoxide. 3 . The method for manufacturing an electrode, according to claim 1 , wherein the silicone includes a hydrophobic functional group. 4 . The method for manufacturing an electrode, according to claim 3 , wherein the hydrophobic functional group includes at least one of a phenyl group, an alkyl group, an alkoxy group, a carbonyl group, and an ester group. 5 . The method for manufacturing an electrode, according to claim 1 , wherein the silicone includes a hydrophilic functional group. 6 . A method for manufacturing an electrode, comprising: forming a mixed liquid of an active material, silicone, a conductive additive, and a first solvent; forming a mixture with a film thereon by spraying the mixed liquid and evaporating the first solvent with a spray dryer; forming a paste including the mixture with the film thereon, a binder, and a second solvent; and forming an active material layer by applying the paste to a current collector and evaporating the second solvent. 7 . The method for manufacturing an electrode, according to claim 6 , wherein the active material includes at least one of graphite, silicon, and silicon monoxide. 8 . The method for manufacturing an electrode, according to claim 6 , wherein the silicone includes a hydrophobic functional group. 9 . The method for manufacturing an electrode, according to claim 8 , wherein the hydrophobic functional group includes at least one of a phenyl group, an alkyl group, an alkoxy group, a carbonyl group, and an ester group. 10 . The method for manufacturing an electrode, according to claim 6 , wherein the silicone includes a hydrophilic functional group.
