Background technology
Lithium primary battery is a kind of high-energy chemistry galvanic cell, is commonly called as lithium battery, with continuing to develop for lithium battery technology, its
Product sexual valence is also constantly lifted, lithium primary battery has that specific energy is big, voltage is high, storage life length, operating temperature range extensively with
And the advantages of environmental protection and public nuisance free, it is widely used in all trades and professions.But, existing coiling lithium one-shot battery negative pole is in electric discharge
In course of reaction, discharge performance is unstable, and it is uneven to easily cause the reaction of lithium piece each several part, and due in existing structure, center
Nickel strap collector and lithium piece cause not of uniform size so that negative pole heat transfer is uneven, there is certain security hidden trouble.
Utility model content
For above-mentioned technical problem, the utility model there is provided one kind effectively improve negative pole currect collecting effect, heat conduction uniformly with
And the high lithium primary battery negative plate of security performance.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of lithium primary battery negative plate, including
Flake main body and lug, the lug are arranged in flake main body, and the flake main body includes the first lithium piece layer, plastic layer and the
Two lithium pieces layer, wherein plastic layer are acid-fast alkali-proof plastic material.
It is preferred that, described lug is the extension part of flake main body.
It is preferred that, the plastic layer is polytetrafluoroethylene (PTFE), is arranged between the first lithium piece layer and the second lithium piece layer, polytetrafluoro
Ethene has antiacid alkali resistant and resistant to elevated temperatures advantage.
It is preferred that, mesh is provided with the plastic layer, mesh is any polygon.
It is preferred that, first lithium piece layer, plastic layer and the second lithium piece layer it is in the same size so that plastic layer is completely overlapped
Between the first lithium piece layer and the second lithium piece layer.
Compared with prior art, the beneficial effects of the utility model are：By in the first lithium piece layer and the second lithium piece layer
Between polytetrafluoroethylene (PTFE), the negative plate of this structure are set so that negative plate monnolithic case is smooth, reduces in lithium primary battery
The potential safety hazard such as reaction uneven and negative pole heat transfer in lithium piece surface is uneven, effectively enhances the use peace of lithium primary battery
Quan Xing, and automated production, machining can be preferably realized, improve production efficiency.

Wherein, 1 is flake main body；2 be lug；11 be the first lithium piece layer；12 be plastic layer；13 be the second lithium piece layer；121
For mesh.
Embodiment
In order that those skilled in the art is better understood from the technical solution of the utility model, below in conjunction with the accompanying drawings to this
The technical scheme of utility model is further elaborated.
Embodiment one：As shown in Figure 1, 2, a kind of lithium primary battery negative plate, including flake main body 1 and lug 2, the pole
Ear 2 is arranged in flake main body 1, and the flake main body 1 includes the first lithium piece layer 11, the lithium piece of plastic layer 12 and second layer 13, its
In, plastic layer 12 is polytetrafluoroethylene (PTFE), and is provided with polygonal mesh 121, improves permeability, is placed in the first lithium piece 11 He of layer
Between second lithium piece layer 13, because plastic layer 12 is identical with the size of the first lithium piece the 11, second lithium piece of layer layer 13, by plastic layer 12
It is completely overlapped between the first lithium piece layer 11 and the second lithium piece layer 13 so that negative plate overall appearance is smooth, it is to avoid existing negative
Because lug 2 and lithium piece layer are of different sizes in pole piece structure, cause the position of lug 2 situation of evagination occur, effectively carry
The high safety in utilization of lithium primary battery negative plate.
Embodiment two：As shown in figure 3, a kind of lithium primary battery negative plate, including flake main body 1 and lug 2, the lug
2 be the extension of flake main body 1, and the flake main body 1 includes the first lithium piece layer 11, the lithium piece of plastic layer 12 and second layer 13,
Wherein, plastic layer 12 is polytetrafluoroethylene (PTFE), and is provided with polygonal mesh 121, improves permeability, is placed in the first lithium piece layer 11
And second between lithium piece layer 13, because the size of plastic layer 12 and the 11, second lithium piece of the first lithium piece layer layers 13 is identical, by plastic layer
12 is completely overlapped between the first lithium piece layer 11 and the second lithium piece layer 13 so that negative plate overall appearance is smooth, and wherein lug 2 is
The extension of flake main body 1, it is to avoid evagination, which occurs, in lug 2 position in existing negative plate structure causes usability difference
Situation, effectively raises the safety in utilization of lithium primary battery negative plate.
During the course of the reaction, each several part active metal lithium can react the lithium primary battery negative plate that the utility model is provided
Uniformly, add the security of product, the monnolithic case of negative plate is smooth, consistency of thickness, reduce because radiating is uneven and caused by
Potential safety hazard, it is and simple in construction, be easy to automated production, machining, improve production efficiency.
Above be the utility model preferably implementation, it is necessary to explanation, without departing substantially from the utility model spirit and
In the case of its essence, those skilled in the art work as can make various corresponding changes and deformation according to the utility model
The scope of the claims appended by the utility model should all be belonged to.
