Abstract
The utility model relates to the technical field of battery manufacture and particularly relates to a novel lithium battery structure. The novel lithium battery structure comprises a body provided with a pole piece and a pole piece membrane therein, and a top part assembly arranged above the body, wherein the pole piece passes through the pole piece membrane to form a pole lug. The novel lithium battery structure is characterized in that the top part assembly comprises an isolating sleeve; the isolating sleeve is arranged on the upper end of the pole piece membrane, and a negative pole lug is inserted at the middle of the isolating sleeve. According to the utility model, the isolating sleeve is arranged on the upper end of the pole piece membrane, and the negative pole lug is inserted at the middle of the isolating sleeve to be protected, thereby effectively preventing the short circuit of the negative pole lug and a lithium battery shell; and meanwhile, the isolating sleeve takes the shape of a flow guide groove at a liquid injection hole to optimize the liquid injection effect of the lithium battery, so that the novel lithium battery structure is quite practical.
Description
Technical field
The utility model relates to battery manufacturing technology field, especially a kind of novel lithium battery structure.
Technical background
Lithium battery is our one of battery commonly used of living, and mainly serves as battery of mobile phone; At present, in the process of producing lithium battery, during owing to encapsulation, especially when lithium battery cover plate encapsulated, deformation took place in its lug easily, caused the lithium battery short circuit; Thereby the damage lithium battery, serious meeting bursts, and this class problem has to be solved.
The utility model content
The utility model provides a kind of can effectively protect lithium battery, especially make the novel lithium battery structure that lug can not be short-circuited.
To achieve these goals, the utility model adopts following technical scheme:
A kind of novel lithium battery structure, it comprises:
One inside is provided with the body of pole piece and pole piece barrier film; With
Be located at the top assembly of body top;
Pole piece forms lug after passing the pole piece barrier film;
Described top assembly comprises a spacer;
Described spacer is located at pole piece barrier film upper end, and negative electrode lug is through in the middle of the spacer.
Preferably, described spacer is that ambroin is made.
Preferably, described top assembly also comprises a liquid injection hole, and at the liquid injection hole place, described spacer is the drainage trough shape.
Owing to adopted such scheme, the utility model is by arranging a spacer in pole piece barrier film upper end, and negative electrode lug is through in the middle of the spacer, is protected, and prevents that effectively negative electrode lug and li battery shell are short-circuited; Simultaneously, spacer is the drainage trough shape at the liquid injection hole place, can optimize the fluid injection effect of lithium battery, has very strong practicality.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the spacer schematic diagram of the utility model embodiment.
Embodiment
As shown in Figure 1, a kind of novel lithium battery structure of present embodiment, it comprises a body 1, body 1 inside is provided with pole piece and pole piece barrier film; Above body 1, it is top assembly; Pole piece forms lug after passing the pole piece barrier film; Top assembly comprises a spacer 2; Spacer 2 is located at pole piece barrier film upper end, and negative electrode lug 3 is through in the middle of the spacer 2.
A preferred aspect as present embodiment:
Preferably, spacer 2 adopts ambroin to make.
Preferably, top assembly also comprises a liquid injection hole, and at the liquid injection hole place, described spacer 2 is the drainage trough shape.
Like this, by in pole piece barrier film upper end one spacer 2 being set, negative electrode lug 3 is through spacer 2
The centre is protected, and prevents that effectively negative electrode lug 3 and li battery shell are short-circuited; Simultaneously, spacer 2 is the drainage trough shape at the liquid injection hole place, can optimize the fluid injection effect of lithium battery, has very strong practicality.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
