Problems solved by technology

On the one hand, the new lithium battery structure effectively solves the problem of lithium battery positive and negative electrode powder dropping, and at the same time, the cell skeleton is added inside the battery to ensure the stability of battery capacity; on the other hand, the lithium battery structure has an exhaust valve that can automatically exhaust and reduce pressure, which not only improves the safety performance, but also prevents the electrolyte from flowing out of the case when the battery is placed upside down

Embodiment 1

[0042] like Figure 1-7 As shown, a new type of lithium battery structure includes an upper cover 1, an O-shaped sealing ring 2 and a housing 3 arranged sequentially from top to bottom; and the upper cover 1, sealing ring 2 and housing 3 form an electrolyte solution closed chamber 4. A negative terminal 5 , a liquid filling hole 6 , an exhaust valve 7 and a positive terminal 8 protrude from the top of the upper cover. An electric core 13 is arranged in the closed cavity 4 . The O-ring is detachably installed between the upper cover 1 and the housing 3 . The upper cover 1 is fixed on the casing 3 by locking screws 11 . In order to make the shell have the performance of flame retardancy, low temperature resistance and no brittle cracking, the shell 3 is made of glass fiber reinforced polypropylene material. like Figure 9 As shown, the battery cell 13 includes a battery core frame 10, a battery pole core 9 wound on the battery core frame 10, and a heat shrinkable tube 12 wr...

Abstract

The invention discloses a novel lithium battery structure. The novel lithium battery structure comprises an upper cover (1), a sealing ring (2) and a shell (3), wherein the upper cover (1), the sealing ring (2) and the shell (3) form an enclosed cavity (4) for containing electrolyte, a negative terminal (5), a charging hole (6), a vent valve (7) and a positive terminal (8) are arranged at the top part of the upper cover in a protruding manner, a battery cell (13) is arranged in the enclosed cavity (4) and comprises a battery cell skeleton (10), a battery pole core (9) and a heat shrinkage tube (12), and the vent valve comprises a venting cavity (102) penetrating through the upper cover (1) and a valve cover (103) covering the venting cavity. According to the novel lithium battery structure, the powder falling-off problem of the positive electrode and the negative electrode of the lithium battery is solved, the battery cell skeleton is additionally arranged inside the battery to ensure the stability of the battery capacity; moreover, the lithium battery structure is provided with the vent valve to be capable of venting and reducing pressure automatically, therefore, the safety performance is improved, and electrolyte cannot flow out of the shell when the novel lithium battery structure is upside down.

Description

technical field [0001] The invention belongs to the field of batteries, in particular, the invention relates to a novel lithium battery structure. Background technique [0002] Ordinary lithium batteries in the prior art usually have the following problems after assembly: (1) the shell vibrates during use, causing the internal powder to fall out of the diaphragm paper; (2) ordinary lithium batteries have only one liquid filling port, when the internal pressure of the battery When it is too large, exhaust and decompression cannot be performed, which not only poses a safety hazard; but also when the lithium battery is placed upside down during use, the electrolyte will flow out of the case. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel lithium battery structure. On the one hand, the new lithium battery structure effectively solves the problem of lithium battery positive and negative electrode powder drop...
