Method of manufacturing battery electrode

A method of manufacturing a battery electrode, comprising separating a battery electrode from a strip-shaped electrode including an application part in which an active material is formed on a collector and a non-application part in which the active material is not formed on the collector such that the non-application part becomes an electrode lead tab, characterized in that,

• when the battery electrode is cut out from the strip-shaped electrode, a collector surface of the application part and a collector surface of the non-application part which will become the electrode lead tab retained in the same plane, and a first cutting line which is defined on an opposite side to a portion from which the electrode lead tab formation part is taken and a second cutting line for taking the electrode lead tab are simultaneously punched out.

A method of manufacturing a battery electrode, comprising separating a battery electrode having a desired size from a strip-shaped electrode in which an active material is intermittently applied onto a collector, characterized in that

• the strip-shaped electrode includes an n-th application part, an n-th non-application part adjoining the n-th application part, and an (n+1)-th application part that adjoins the n-th non-application part on an opposite side at which the n-th application part adjoins the n-th non-application part (n is a positive integer),
• and
• the battery electrode is cut out from the strip-shaped electrode, including at least the n-th application part, n-th non-application part, and (n+1)-th application part.

A battery characterized by comprising a positive electrode and a negative electrode which are stacked through a separator,

• the positive electrode being cut out, from a strip-shaped electrode in which an active material is intermittently applied onto a collector and which includes an n-th application part, an n-th non-application part adjoining the n-th application part, and an (n+1)-th application part that adjoins the n-th non-application part on an opposite side at which the n-th application part adjoins the n-th non-application part (n is a positive integer), including at least the n-th application part, n-th non-application part, and (n+1)-th application part,
• the negative electrode being produced in the same manner as the positive electrode.
