Abstract
The utility model relates to a novel lithium ion power battery structure. The novel lithium ion power battery structure is formed by connecting two battery cells in parallel, each battery cell is formed by alternatively stacking 48 small anode plates and 49 small cathode plates, a diaphragm is arranged between each small anode plate and each small cathode plate, and aluminium foils on the small anode plates and the aluminium foils on the small cathode plates are respectively connected with an anode conductive cylinder and a cathode conductive cylinder. The battery cells are wrapped by a housing, and the node conductive cylinder and the cathode conductive cylinder both extend out of the housing. The novel lithium ion power battery structure has the advantages of being small in internal resistance and safe in use.
Description
[technical field]
The utility model relates to a kind of battery, is specifically related to a kind of new type lithium ion electrokinetic cell structure.
[background technology]
The conventional structure of the lithium-ion-power cell of prior art is that rolled electric core is enclosed in the circular or square container and forms battery.But, this battery at work because internal resistance is big, it is more to produce heat, often shortens the useful life of battery greatly because can not well dispel the heat, even causes potential safety hazard.
For solving the problems of the technologies described above, necessary a kind of structure improved lithium-ion-power cell structure that has is provided, to overcome said defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of the utility model is the new type lithium ion electrokinetic cell structure that provides a kind of internal resistance little, safe in utilization.
For realizing above-mentioned purpose; The technical scheme that the utility model is taked is: be formed in parallel by two electric cores; Each electric core is formed by 48 just minimum pole pieces and 49 little pole piece alternated of negative pole; And be provided with barrier film between each just minimum pole piece and the little pole piece of negative pole, the aluminium foil on the just minimum pole piece is connected with the negative pole conductive pole with anodal conductive pole respectively with Copper Foil on the little pole piece of negative pole.
The lithium-ion-power cell structure of the utility model further is set to: said electric core is wrapped up by shell.
Compared with prior art, the utlity model has following beneficial effect:
The lithium-ion-power cell structure of the utility model is through becoming electric core with just minimum pole piece with the little pole piece alternated of negative pole, again and be unified into battery, thereby this internal resistance of cell diminished, and it is less to produce heat in the course of work, helps improving the fail safe of use.
[description of drawings]
Fig. 1 is the plan structure sketch map of single electric core.
Fig. 2 is just minimum pole piece structural representation.
Fig. 3 is the little pole piece structural representation of negative pole.
[embodiment]
See also shown in Figure of description 1 to the accompanying drawing 3; The utility model is a kind of lithium-ion-power cell structure; Be formed in parallel by two electric cores 1; Each electric core 1 is formed by 48 just minimum pole pieces 2 and 49 little pole piece 3 alternated of negative pole, and is provided with barrier film 4 between each just minimum pole piece 2 and the little pole piece 3 of negative pole, and the aluminium foil 5 on the just minimum pole piece 2 is connected with the negative pole conductive pole with anodal conductive pole respectively with Copper Foil 6 on the little pole piece 3 of negative pole.
By shell 7 parcels, and anodal conductive pole (not shown) and negative pole conductive pole (not shown) all stretch out outside the shell 7 with the electric core 1 of two parallel connections.
The lithium-ion-power cell structure of the utility model is through becoming electric core 1 with little pole piece 3 alternated of just minimum pole piece 2 and negative pole, again and be unified into battery, thereby this internal resistance of cell diminished, and it is less to produce heat in the course of work, helps improving the fail safe of use.
Above embodiment is merely the preferred embodiment of this creation, not in order to limiting this creation, any modification of being made within all spirit and principles in this creation, is equal to replacement, improvement etc., all should be included within the protection range of this creation.
