Abstract
The utility model discloses a kind of lithium coin cells with open-cell pole piece, including being provided with insulator seal ring between being closed up on negative cover, anode cover, negative cover outer rim and anode cover, lithium-ion negative pole piece, battery diaphragm, positive plate are from top to bottom sequentially provided with anode cover, pole piece steel loop is provided between positive plate and anode cover, electrolyte is filled with anode cover, the positive plate offers at least one perforate；Because positive plate is provided with perforate, on the premise of it ensure that the diameter and thickness of battery anode slice, the storage area of electrolyte is effectively increased, more preferably activity is provided by increase electrolysis liquid energy, so as to improve the performance of lithium coin cells and service life.
Description
Technical field
A kind of lithium coin cells are the utility model is related to, particularly a kind of lithium coin cells with open-cell pole piece.
Background technology
Lithium coin cells refer to lithium ion battery of the appearance and size as a small button, the button for prismatic battery
Cell diameter is larger, thinner thickness, and such as thickness is only 1.6mm, 3.2 mm.Lithium coin cells structure is as shown in figure 1, including negative
Insulator seal ring 3 ' is provided between being closed up on polar cap 1 ', anode cover 2 ', negative cover outer rim and anode cover, in anode cover from top to bottom
Lithium-ion negative pole piece 4 ', battery diaphragm 5 ', positive plate 6 ' are sequentially provided with, pole piece steel loop 9 ', anode cover is interior to be filled with electrolyte；
Existing lithium coin cells are using one piece of relatively thin negative plate and the pairing structure of one piece thicker of carbon-based positive plate.For this
For class battery, electrolyte is more in theory, and its performance and service life are more secure, but due to positive plate and other parts
Occupy larger space.Therefore, how rational modification structure turns into the utility model people in order to store more electrolyte
The content of primary study.
Utility model content
The technical problems to be solved in the utility model, which is to provide one kind, can store more electrolyte, space availability ratio height, make
With the lithium coin cells with open-cell pole piece of long lifespan.
In order to solve the above-mentioned technical problem, the lithium coin cells of the present utility model with open-cell pole piece, including negative pole
Insulator seal ring is provided between being closed up on lid, anode cover, negative cover outer rim and anode cover, is from top to bottom sequentially provided with anode cover
Lithium-ion negative pole piece, battery diaphragm, positive plate, pole piece steel loop is provided between positive plate and anode cover, electricity is filled with anode cover
Liquid is solved, the positive plate offers at least one perforate.
Further improvement of the utility model, the perforate are through hole, blind hole or the recess being opened on positive plate.
Further improvement of the utility model, the through hole are opened among positive plate.
The beneficial effects of the utility model are：Because positive plate is provided with perforate, ensure that the diameter of battery anode slice and
On the premise of thickness, the storage area of electrolyte is effectively increased, more preferably activity is provided by increase electrolysis liquid energy, so as to
Improve the performance and service life of lithium coin cells.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation of traditional lithium coin cells.
Fig. 2 is structural representation of the present utility model.
Embodiment
Shown in reference picture 2, there are the lithium coin cells of open-cell pole piece, including outside negative cover 1, anode cover 2, negative cover 1
On edge and anode cover 2 close up between be provided with insulator seal ring 3, be from top to bottom sequentially provided with anode cover 2 lithium-ion negative pole piece 4,
Battery diaphragm 5, positive plate, pole piece steel loop is provided between positive plate and anode cover 2, electrolyte, positive plate are filled with anode cover 2
Offer at least one perforate.Further, perforate is the through hole, blind of the up/down perforation around being opened among positive plate or being middle
Hole or recess.Because positive plate is provided with perforate, on the premise of it ensure that the diameter and thickness of battery anode slice, effectively carry
The high storage area of electrolyte, so as to improve the performance of lithium coin cells and service life.
Simply the utility model preferred embodiment described above, it is not formed to scope of protection of the utility model
Limitation, as long as realize that the purpose of this utility model should all belong to the scope of protection of the utility model with essentially identical means.
