Abstract
The utility model is related to a battery, which overcomes the shortcomings of other lithium batteries. The utility model is composed of a shell body, an inner ring lithium plate, a diaphragm, C-shaped positive carbon plates, an outer ring lithium plate and a connecting shrapnel, which are connected with each other. In the shell body, the inner ring lithium plate is a solenoid with the outer ring lithium plate, the diaphragm and the positive carbon plate rolled in overlapping; the inner ring lithium is therein inserted with the connecting shrapnel; and the positive tab is positioned in the middle of the C-shaped carbon plates to lead out the electrode of the positive carbon plate from the winding body and to be connected with the positive post; the negative lithium plate is divided into an outer ring lithium plate and an inner lithium plate and is connected between the C-shaped positive plate notch and the inner shell of the shell body. The utility model has the advantages of the full space utilization, high positive utilization rate and high safe coefficient.
Description
One, technical field:
The utility model relates to a kind of battery, especially two negative pole lithium batteries.
Two, background technology:
Existing cell shapes and structure are varied, no matter be carbon packet mode or takeup type, its negative pole, positive pole all have only one, and so anodal utilance is not high.
Three, summary of the invention:
The purpose of this utility model provides a kind of space that makes full use of, two negative pole lithium batteries of augmenting response area, it has overcome the shortcoming that other lithium battery exists, the purpose of this utility model is to realize like this, it is to be formed by connecting by housing, inner ring lithium sheet, barrier film, anodal carbon plate, outer ring lithium sheet and afflux shell fragment, in housing, inner ring lithium sheet is a circle tube, and its outer ring has outer ring lithium sheet, barrier film, the overlapping volume of anodal carbon plate to put; In inner ring lithium sheet, be inserted with the afflux shell fragment; Anodal carbon plate is the C body, anode ear is positioned in the middle of the C type carbon plate, the electrode of anodal carbon plate is drawn with positive terminal be connected from coiling body, and negative pole lithium sheet is divided into outer ring lithium sheet, inner ring lithium sheet, it connects from C type positive plate indentation, there and connects, and negative lug is connected on the inner walls.
Meaning of the present utility model is to make full use of the space, anodal utilance height, coefficient of safety height.
Four, description of drawings:
Fig. 1 is the structural representation of two negative pole lithium batteries, among the figure 1, housing 2, barrier film 3, anodal carbon plate 4, inner ring lithium sheet 5, outer ring lithium sheet 6, afflux shell fragment
Five, embodiment:
In Fig. 1, in housing 1, inner ring lithium sheet 4 is a circle tube, and its outer ring has outer ring lithium sheet 5, barrier film 2, anodal carbon plate 3 overlapping volumes to put; In inner ring lithium sheet 4, be inserted with afflux shell fragment 6; Anodal carbon plate 3 is the C body, anode ear is positioned in the middle of the C type carbon plate, the electrode of anodal carbon plate is drawn with positive terminal be connected from coiling body, and negative pole lithium sheet is divided into outer ring lithium sheet 5, inner ring lithium sheet 4, it connects from C type positive plate indentation, there and connects, and negative lug is connected on housing 1 inwall.
