【0026】 本発明の電極シートは、表裏両面の活性物質層の電極タブに近い一端に異なる色の絶縁層を設置するため、絶縁層の色を観察することによって、電極シートの表裏面を効果的に区別することができ、電極シートの表裏面が逆になるのを防ぐことができる。また、絶縁層は、化学反応に参加しないため、絶縁層で電極シートの表裏面を識別することによって、追加のマーキングが不要となり、電池への影響が小さくなる。

Abstract
To provide an electrode sheet, a battery, and an electronic device that can effectively distinguish front and back surfaces of the electrode sheet.SOLUTION: The present invention provides an electrode sheet, a battery, and an electronic device, and specifically relates to a battery manufacturing technique field. The electrode sheet includes a current collector, an electrode tab, an active material layer, and an insulating layer. The current collector has a first front surface and a second front surface that are disposed relatively. The electrode tab projects from the current collector. The active material layer is installed on the first front surface and the second front surface. The insulating layer overlaps one end of the active material layer that is close to the electrode tab at least partially or has a gap therebetween. The insulating layer includes a first insulating layer disposed on the first front surface and a second insulating layer disposed on the second front surface. The first insulating layer and the second insulating layer are different in color. The present invention can distinguish the front and back surfaces of the electrode sheet by observation of the color of the first insulating layer and the second insulating layer.SELECTED DRAWING: Figure 4
