Abstract

The invention discloses a cylindrical battery and a packaging method thereof. The packaging method comprises the following steps of: sticking a red mylar tape at the joint of a positive tab and a battery body along the extension direction of the positive tab; folding flatly the positive tab, pasting a first dark brown high-temperature adhesive to the joint of the positive tab and the battery bodyin the direction perpendicular to the extending direction of the positive tab; adhering a black mylar tape to the joint of a negative tab and the battery body along the extension direction of the negative tab; flatly folding the negative tab, and pasting a second dark brown high-temperature adhesive to the joint of the negative tab and the battery body in the direction perpendicular to the extending direction of the negative tab; cutting the exposed ends of the positive tab and the negative tab to the required length; and adhering a third dark brown high-temperature adhesive to the two sealedside edges of the battery body. The red mylar tape and the black mylar tape are respectively adhered to the positive tab and the negative tab, so that the packaging effect can be achieved, a positiveelectrode and a negative electrode are easy to distinguish, the diameter of a finished battery is not increased, and the transportation cost is reduced.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a cylindrical battery and a packaging method thereof. Background technique [0002] As an environmentally friendly secondary battery, lithium-ion batteries have been widely used in portable devices such as mobile phones, cameras, and notebook computers. However, with the development of modern society, many portable devices are moving towards intelligence and multi-function. In order to meet their capacity and power requirements and ensure their sufficient use time, their power sources must have higher energy density. . [0003] Existing cylindrical lithium-ion batteries are generally packaged in a thermoplastic tube. This packaging method has the following problems: 1. It will increase the diameter of the finished battery, which will increase the transportation cost; 2. The positive and negative electrodes of the battery are not It is easy to distinguish, and it is easy to install it b...
