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 method of manufacturing the same, and in particular, the present invention relates to a thin lithium battery having a collector to externally exposed to the exterior of a single euro-ear collector structure without a separate eclip or terminal portion. Production method. Further, it is directed to a thin lithium battery and a manufacturing method thereof, wherein since the thin lithium battery has flexibility, it can be applied to a flexible device, and since the thin lithium battery does not require a separate terminal portion, it can be cut, stamped. Or a dowrtinating such as laser cutting to achieve dimensions and design. Background technique [0002] With the development of the recent communication technology and semiconductor manufacturing technology, the relevant industries of the portable electronic equipment continue to expand. In order to prevent the depletion of fossil fuel and protect ...
