Problems solved by technology

[0005] However, even this soft-packed lithium secondary battery has the following problems: it becomes a factor limiting the shape and size of the lithium secondary battery in terms of packaging; since the existing soft-packed lithium secondary battery includes electrode tabs, Each electrode needs to be connected to tabs; a plurality of said soft-packed lithium secondary batteries cannot be packaged simultaneously at one time; it is difficult to manufacture and the productivity is reduced; and it is difficult to apply to various electronic products
[0006] In addition, in the era of the Internet of Things (IoT, Internet of Things), the demand for thin power supplies of various designs that can be used in low-power and small-capacity devices is increasing, but the existing button batteries have a uniform design and a thick thickness. Shortcomings
In addition, the existing pouch thin batteries have the following limitations: uniform design; due to the tabs, the production is complicated and the price is high

Abstract

The present invention relates to a thin lithium battery and a method for manufacturing the same. Specifically, the present invention relates to a thin lithium battery having a tabless current collecting structure that does not require a separate tab or terminal unit because a current collector is exposed to the outside, and a method for manufacturing the same. In addition, the present invention relates to a thin lithium battery and a method for manufacturing the same, wherein the thin lithium battery has flexibility and can thus be applied to flexible devices, and does not require a separate terminal unit and can thus be manufactured into a wide variety of dimensions and designs by punching, such as by cutting, stamping, or laser cutting.

Description

Technical field [0001] The present invention relates to a thin lithium battery and a manufacturing method thereof. Specifically, the present invention relates to a thin lithium battery with a tabless current collection structure in which the current collector is exposed to the outside and does not require separate tabs or terminal parts, and a thin lithium battery with a tabless current collection structure. Manufacturing method. In addition, it relates to a thin lithium battery and a manufacturing method thereof. Since the thin lithium battery is flexible, it can be applied to flexible devices, and since the thin lithium battery does not require a separate terminal portion, it can be cut or punched. Or blanking such as laser cutting to achieve diversification in size and design. Background technology [0002] With the recent development of communication technology and semiconductor manufacturing technology, the industry related to portable electronic devices has been expan...
