Embodiment Construction

[0021] Hereinafter, specific implementation manners of the present application will be described in detail with reference to the accompanying drawings.

[0022] like figure 1 As shown, the lithium ion battery 1 of the present application includes a substantially rectangular case 10, a battery cell 14 (for example, JR (jacket cell)) disposed inside the case 10, and a pole embedded in the top end of the case 10. 12 and the tab 16 arranged between the pole 12 and the battery core 14 .

[0023] Specifically, one end of the pole 12 protrudes into the housing 10 and the other end protrudes out of the housing 10 . The tab 16 includes a base 160 extending directly from the battery core 14 , a connecting section 164 extending from the base and forming a connecting section 164 , and extending from the base 160 approximately in the middle and forming between the base 160 and the connecting section. 164 between the bent section 162. The connection section 164 and the bent section 162 a...

Abstract

The application provides a lithium battery. The lithium battery is provided with a casing, a battery core, an electrode pole and an electrode lug, wherein the battery core is arranged in the casing; the electrode pole is arranged on the casing and extends out of the casing; the electrode lug comprises a base part extending out from the battery core and a connecting section formed by extending and combining from the base part; the connecting section is electrically fixedly connected with the bottom of the electrode pole directly. Through the adoption of the lithium battery, the size of the battery in the thickness direction can be reduced, and the reliability can be improved.
