Title:

POSITIVE ELECTRODE FOR SECONDARY BATTERIES, AND SECONDARY BATTERY

Document Type and Number:

WIPO Patent Application WO/2024/095670

Kind Code:

A1

Abstract:

A positive electrode (11) as an embodiment comprises a positive electrode core (30) and positive electrode mixture layers (31) disposed on the positive electrode core (30). The positive electrode mixture layers (31) each comprise first regions (35) and second regions (36) which are alternately arranged in the length direction and/or the width direction of the positive electrode core (30). The first regions (35) and the second regions (36) include a positive electrode active material, a binder and a conductive agent. The content ratio of the conductive agent in the second regions (36) is higher than the content ratio of the conductive agent in the first regions (35).
