Abstract

Official abstract text for this publication.

An electrode manufacturing apparatus includes a film forming device that forms an electrode layer on a surface of a substrate. The film forming device includes a first roll that rotates, a second roll that is spaced apart from and opposed to the first roll and rotates in an opposite direction of the first roll, a third roll that is spaced apart from and opposed to the second roll and rotates in the opposite direction of the second roll, and a temperature adjusting unit that reduces a temperature difference between a central portion and an end portion in an axial direction of at least one roll of the first roll, the second roll, and the third roll.

First claim

Opening claim text (preview).

What is claimed is: 1 . An electrode manufacturing apparatus comprising a film forming device configured to form an electrode layer on a surface of a substrate, the film forming device including: a first roll configured to rotate; a second roll that is spaced apart from and opposed to the first roll and configured to rotate in an opposite direction of the first roll; a third roll that is spaced apart from and opposed to the second roll and configured to rotate in the opposite direction of the second roll; and a temperature adjusting unit configured to reduce a temperature difference between a central portion and an end portion in an axial direction of at least one roll of the first roll, the second roll, and the third roll. 2 . The electrode manufacturing apparatus according to claim 1 , wherein the temperature adjusting unit is configured to adjust a temperature of at least the second roll. 3 . The electrode manufacturing apparatus according to claim 2 , wherein the temperature adjusting unit is configured to adjust the temperature of at least the third roll. 4 . The electrode manufacturing apparatus according to claim 1 , wherein the temperature adjusting unit has a cooling device that cools the end portion. 5 . The electrode manufacturing apparatus according to claim 1 , wherein the temperature adjusting unit has a heating device that heats the central portion. 6 . The electrode manufacturing apparatus according to claim 1 , wherein the film forming device further includes temperature sensors that detect temperatures of the central portion and the end portion. 7 . The electrode manufacturing apparatus according to claim 1 , further comprising a controller configured to control the temperature adjusting unit such that the temperature difference becomes equal to or smaller than a predetermined value. 8 . An electrode manufacturing apparatus comprising a film forming device configured to form an electrode layer on a surface of a substrate, the film forming device including: a first roll configured to rotate; a second roll that is spaced apart from and opposed to the first roll and configured to rotate in an opposite direction of the first roll; a third roll that is spaced apart from and opposed to the second roll and configured to rotate in the opposite direction of the second roll; and a temperature adjusting unit configured to heat only a central portion in an axial direction of at least one roll of the first roll, the second roll, and the third roll. 9 . An electrode manufacturing apparatus comprising a film forming device configured to form an electrode layer on a surface of a substrate, the film forming device including: a first roll configured to rotate; a second roll that is spaced apart from and opposed to the first roll and configured to rotate in an opposite direction of the first roll; a third roll that is spaced apart from and opposed to the second roll and configured to rotate in the opposite direction of the second roll; and a temperature adjusting unit configured to cool only opposite end portions in an axial direction of at least one roll of the first roll, the second roll, and the third roll.
