Abstract
Official abstract text for this publication.
Part of an electrode, specifically a current collector and an active material layer, for a secondary battery is subjected to cutting processing to have a complex shape. For example, a stack of the first current collector and the first active material layer has a first slit and a second slit. Each of the first slit and the second slit passing across the first current collector and the first active material layer and extending from an edge of the first current collector. Another stack of the second current collector and the second active material layer has a third slit and a fourth slit. Each of the third slit and the fourth slit passing across the second current collector and the second active material layer and extending from an edge of the second current collector.
First claim
Opening claim text (preview).
1 . (canceled) 2 . A secondary battery comprising: a current collector having an L-shaped portion, wherein the current collector comprises a first side and a second side, wherein the first side and the second side constitutes an inside part of the L-shaped portion, wherein a periphery of the current collector comprises a curved portion between the first side and the second side, and wherein the current collector does not exist at an intersectional point formed by an extension line of the first side and an extension line of the second side. 3 . A secondary battery comprising: a current collector having an L-shaped portion, wherein the current collector comprises a first side and a second side, wherein the first side and the second side constitutes an inside part of the L-shaped portion, wherein a periphery of the current collector comprises a curved portion between the first side and the second side, and wherein the curved portion has a concaved shape toward an inner part from the periphery of the current collector.
