Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Please also see figure 1 with figure 2 , a lithium battery 100 in an embodiment includes a plastic case 10 , a protective plate 20 and a cell 40 .

[0030] The plastic case 10 includes a bottom plate 11 , a side plate 12 and a holding portion 15 . The bottom plate 11 is generally strip-shaped. The side panel 13 is bent and extended from the edge of the bottom panel 11 . An injection port 121 is opened on the side plate 12 .

[0031] The clamping portion 15 is located on the inner surface of the side plate 13 of the plastic case 10 for fixing the protection plate 20 . The clamping portion 15 is a protrusion protruding from the inner surface of the side plate of the plastic shell 10 , and the clamping portion 15 has a mating surface 151 . In this embodiment, the clamping portion 15 is strip-shaped with a quarter-circle cross section, the mating surface 151 ...

Abstract

A lithium battery comprises a rubber casing, a guard plate and a battery cell, wherein the guide plate is fixedly connected with the battery cell, a clamping portion is arranged on the rubber casing, and the guard plate is held in the rubber casing and is fixedly on the same via the clamping portion. By arranging the clamping portion on the rubber casing, the guard plate can be fixed on the rubber casing via elastic deformation of the clamping portion, so that assembling of the lithium battery is simpler, the problem that the lithium battery is not attractive enough in appearance since the guard plate needs to be fixed by a double-faced adhesive tape or by tapping a hole on the rubber casing is avoided, so cost of the lithium battery is lowered, and appearance of the lithium battery is improved. Furthermore, the invention provides a lithium battery packaging process. The lithium battery packaging process includes the steps of providing the rubber casing with clamping portion and fixing the guard plate via the clamping portion. By the simple packaging process, the cost of the lithium battery is lowered, and appearance of the lithium battery is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery and a lithium battery packaging process. 【Background technique】 [0002] The current low-pressure injection molding packaging process for lithium batteries often uses the casing injection molding process to replace the traditional pure low-pressure injection molding process for packaging. The fixing of the protective plate and the plastic case in the casing injection molding process is an important step in the battery packaging process. Conventional fixing of the protective plate and the rubber shell adopts the method of double-sided tape or the hole of the rubber shell to clip the protective plate. This fixing method is cumbersome and time-consuming; the second is that the appearance of the battery is not beautiful. 【Content of invention】 [0003] Based on this, it is necessary to provide a low-cost lithium battery and improve the appearance of t...
