Abstract
The utility model relates to the field of batteries, and in particular relates to a thin-shell lithium battery with improved volumetric specific energy. The thin-shell lithium battery comprises a battery shell which comprises an anode shell and a cathode cover group. The anode shell is a shell with an opening, and the cathode cover group is in an integral structure which is formed by injecting a plastic component in the periphery of the outer turnup of the cathode cover of a metal shell. The battery shell is made of a stainless steel belt which is 0.20mm thick. According to the shell lithium battery provided by the utility model, on the premise of not changing the shape and structural strength of the button lithium battery, the stainless steel material which is 0.20mm thick is used as the shell material of the button lithium battery, so that the inner space of the battery is expanded, the quantity of active substances for battery discharge is increased, and the discharge performance of the battery is improved. Compared with the existing button lithium batteries, the thin-shell lithium battery has the advantages that the volumetric specific energy of the thin-shell lithium battery provided by the utility model is improved by more than 15%, and the weight of the stainless steel belt used by each button lithium battery is reduced by 15-20%, so that the cost of the battery is greatly reduced.
Description
Technical field
The utility model relates to field of batteries, the shell lithium battery that especially a kind of volumetric specific energy has improved.
Background technology
The sheathing material of existing button lithium battery is stainless steel band, and thickness is the stainless steel band of 0.25mm, existing button lithium battery technology is very ripe, if can be under the existing technical prerequisite that does not change battery outward appearance and structural strength expansion inside battery space, just can increase the battery discharge amount of active material, thereby improve the discharge performance of battery, and the volumetric specific energy of button lithium battery is also along with having improved.
The utility model content
The technical problems to be solved in the utility model is: the shell lithium battery that the discharge performance, the volumetric specific energy that based on the problems referred to above, provide a kind of and reduced the battery cost, improve battery improved.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of shell lithium battery, has battery case, described battery case comprises anode cover and negative cover group, described anode cover is a uncovered housing, the integrative-structure that the negative cover flanging perimeter injection moulding that described negative cover group is metal shell has plastic parts to consist of, the material of described battery case is stainless steel band, and the thickness of stainless steel band is 0.20mm.
Further, the height of described anode cover is 1.4～1.8mm.Because the material of battery case is stainless steel band, the thickness of stainless steel band is 0.20mm, than the stainless steel band thickness of existing battery case little 0.05mm, so the anode cover attenuation, the height of anode cover has just reduced.
Further, the height of described negative cover group is 1.2～1.9mm.Because the material of battery case is stainless steel band, the thickness of stainless steel band is 0.20mm, thus the height of anode cover reduced, for keeping battery outward appearance and structural strength, so the height of negative cover group has raise.
The beneficial effects of the utility model are: the utility model is under the prerequisite that does not change button lithium battery outward appearance and structural strength, use the stainless steel material of 0.20mm thickness instead as the sheathing material of button lithium battery, expanded the inner space of battery, increase the amount of battery discharge with active material, improved the discharge performance of battery.Volumetric specific energy of the present utility model is compared existing button lithium battery and has been improved more than 15%, and the employed stainless steel band weight of each button lithium battery descended 15%～20%, greatly reduces the cost of battery.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
Among the figure: 1. battery case, 2. anode cover, 3. negative cover group, 4. negative cover.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of shell lithium battery as shown in Figure 1, has battery case 1, battery case 1 comprises anode cover 2 and negative cover group 3, anode cover 2 is a uncovered housing, the integrative-structure that negative cover group 3 has plastic parts to consist of for the negative cover 4 flanging perimeter injection mouldings of metal shell, the material of battery case 1 is stainless steel band, and the thickness of stainless steel band is 0.20mm.
Further, the height of anode cover 2 is 1.4～1.8mm.Because the material of battery case 1 is stainless steel band, the thickness of stainless steel band is 0.20mm, than the stainless steel band thickness of existing battery case 1 little 0.05mm, so anode cover 2 attenuation, the height of anode cover 2 has just reduced.
Further, the height of negative cover group 3 is 1.2～1.9mm.Because the material of battery case 1 is stainless steel band, the thickness of stainless steel band is 0.20mm, thus the height of anode cover 2 reduced, for keeping battery outward appearance and structural strength, so the height of negative cover group 3 has raise.
Because the material of battery case 1 is stainless steel band, the thickness of stainless steel band is 0.20mm, than the stainless steel band thickness of existing battery case 1 little 0.05mm, so anode cover 2 attenuation, the height of anode cover 2 has just reduced, for keeping battery outward appearance and structural strength, so the height of negative cover group 3 has raise, the inner space of final battery has been expanded, and has increased the amount of battery discharge with active material, has improved the discharge performance of battery.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
