Embodiment Construction

[0022] The specific embodiments and examples of the present invention will be described in detail below in conjunction with the accompanying drawings. The described specific embodiments are only used to explain the present invention, and are not intended to limit the specific embodiments of the present invention.

[0023] Such as figure 1 as shown, figure 1 It is a three-dimensional view of the pole piece with tabs of the present invention, the pole piece includes a current collector sheet 100, and a dressing area 110 and a blank area 120 connected up and down (or connected left and right) are arranged on the current collector sheet 100 , the dressing area 110 is used to coat the positive electrode material (or negative electrode material). On the edge of the blank area 120, a tab area 130 is partially extended. The tab area 130 is integrally connected with the blank area 120 and has the same thickness. The tab area The extension direction of 130 is opposite to that of the au...

Abstract

The invention discloses an intelligent IC card, an ultrathin battery and a pole piece with a tab of the ultrathin battery. The pole piece comprises a current collector piece, wherein the current collector piece is provided with connected dressing area and blank area; an integrally connected tab area extends on local edge of the blank area; and the tab area and the dressing area are located at two sides of the blank area. Due to the adoption of the tab which is integrally connected with the current collector piece, the welding mode of superposing a tab piece on the current collector piece is creatively avoided, the thickness of the pole piece is obviously reduced, the bottleneck that a polymer ultrathin soft package secondary battery cannot be easily improved towards a smaller thickness direction is broken through, and the pole piece has important practical value and significance in popularization and development of the intelligent IC card with the battery.

Description

technical field [0001] The invention relates to the field of smart IC cards with batteries, in particular to a pole piece used in an ultra-thin battery. Background technique [0002] With the intelligent development of society, all kinds of magnetic stripe cards are also shifting towards chip cards, especially bank cards, which are currently being replaced from magnetic stripe cards to chip cards on a large scale. , in the near future, various chip-based bank cards, ID cards (ID cards), social security cards, and provident fund cards will also develop into smart IC cards with batteries. higher requirements. [0003] However, polymer ultra-thin soft-packaged secondary batteries in the prior art, such as lithium-ion batteries, are limited by their internal structures and have a thickness of more than 1mm. Especially, the positive and negative electrodes often need to be welded to the corresponding electrodes Ear, which limits the bottleneck of the polymer ultra-thin flexible...
