Abstract
The utility model relates to a cylindrical lithium battery which comprises a cylindrical shell. At least two single bare core bodies are arranged in the cylindrical shell and are connected in series. The cylindrical lithium battery has the advantages of low assembly cost, high energy density and attractive appearance.
Description
Technical field
The utility model belongs to the battery technology field, relates in particular to a kind of cylinder type lithium battery.
Background technology
The connection of traditional cylindrical lithium battery group is through cylinder type lithium battery monomer and the monomer series-connected battery pack structure of forming of cylinder type lithium battery; Every cylinder type lithium battery monomer of this structure has all comprised naked electric core, outer protection shell, and not only wasting space, and assembly cost is too high, and outward appearance is not attractive in appearance.
Summary of the invention
To above-mentioned technological deficiency, the technical problem that the utility model need solve provides that a kind of assembly cost is low, energy density is high, the cylinder type lithium battery of good looking appearance.
The technical problem that the utility model need solve realizes through following technical scheme: a kind of cylinder type lithium battery comprises being provided with naked electric core monomer in cylindrical shell, the cylindrical shell that described naked electric core monomer has 2 at least, is connected in series between the naked electric core monomer.
Further: in above-mentioned cylinder type lithium battery, be connected in series through headtotail between the naked electric core monomer.Connect through metal lead wire or sheet metal between the naked electric core monomer.
Perhaps: realize being connected in series through connector between the naked electric core monomer.Described connector is metal lead wire or sheet metal.
Described metal lead wire or sheet metal are the extraction electrodes of naked electric core monomer.
Compared with prior art, above-mentioned cylinder type lithium battery comprises being provided with naked electric core monomer in cylindrical shell, the cylindrical shell that described naked electric core monomer has 2 at least, is connected in series between the naked electric core monomer.During assembling, at first that naked electric core is monomer series-connected, the naked electric core that will be together in series then reinstalls in the cylindrical shell.So the utility model beneficial technical effects is:
1, adopt series system between the naked electric core monomer, operation is simple, saves cost;
2, all naked electric core monomer is all in a cylindrical shell, helps the integrality of whole cylinder type lithium battery and better outward appearance;
3, can save the space, promote the energy density of whole cylinder type lithium battery.
Description of drawings
Fig. 1 is the structure diagram of the utility model execution mode;
Wherein, 1 cylindrical shell, 2 naked electric core monomers, 3 connectors.
Specific embodiments
With reference to accompanying drawing and embodiment the utility model is described.
A kind of cylinder type lithium battery comprises being provided with naked electric core monomer 2 in cylindrical shell 1, the cylindrical shell 1 that described naked electric core monomer has 2, is connected in series between the naked electric core monomer.Be connected in series through headtotail between the naked electric core monomer.Connect through metal lead wire or sheet metal between the naked electric core monomer.
Realize being connected in series through connector 3 between the perhaps naked electric core monomer.Described connector 3 is metal lead wire or sheet metal.
Described metal lead wire or sheet metal are the extraction electrodes of naked electric core monomer.
During assembling, at first naked electric core monomer 2 is together in series, the naked electric core monomer 2 that will be together in series then reinstalls in the cylindrical shell 1.
2 of naked electric core monomers adopt series system, and operation is simple, save cost; All naked electric core monomers 2 help the integrality and better outward appearance of whole cylinder type lithium battery in a cylindrical shell 1; Can save the space, promote the energy density of whole cylinder type lithium battery.
The above is the preferred embodiment of the utility model, is not breaking away under the utility model design situation, carries out any conspicuous distortion and replacement, all belongs to the utility model protection range.
