COLLECTOR SHEET AND ELECTROCHEMICAL DEVICE

摘要

The invention provides a current collector sheet for carrying an electrode material mixture for use in an electrode for an electrochemical device characterized in that the current collector sheet has a conductive area and an insulating area on the surface thereof. Examples of the current collector sheet includes: a current collector sheet including an insulating sheet, wherein the conductive area is a conductive layer formed on the surface of the insulating sheet, and the insulating area is an exposed portion of the insulating sheet; a current collector sheet including a conductive sheet, wherein the insulating area is an insulating layer formed on the surface of the conductive sheet, and the conductive area is an exposed portion of the conductive sheet; and a current collector sheet including a conductive sheet portion and an insulating sheet portion positioned flush with each other, wherein the conductive area is a surface of the conductive sheet portion, and the insulating area is a surface of the insulating sheet portion.
