Abstract
The utility model provides an oval polymer lithium ion battery, comprising a shell, a positive pole piece provided with a pole lug and a negative pole piece provided with a pole lug, wherein the shell is an oval column body; the positive pole piece and the negative pole piece are arranged in the oval column body; and the two pole lugs are respectively arranged at the two ends of the oval column body. In the oval polymer lithium ion battery, the battery shell is the oval column body and has larger volume and space, and when being assembled in an electronic product, the oval polymer lithium ion battery does not occupy a large position, so that the structural design of the product is convenient.
Description
Technical field
The utility model relates to polymer Li-ion battery, a kind of specifically oval polymer Li-ion battery.
Background technology
At present, the shape of the polymer Li-ion battery of being sold on the market is mainly square and cylindrical two kinds.The electric core volume of square polymer Li-ion battery is bigger, and energy density is low, and the space utilance is higher in electronic product; And the electric core volume of cylindrical polymeric lithium ion battery is less, and energy density is higher, but the space utilance is lower in electronic product.In sum, square and columniform polymer Li-ion battery in use all has the some shortcomings part.Along with the miniaturization of electronic product, weak point square and columniform polymer Li-ion battery becomes increasingly conspicuous, and can't satisfy the topology requirement of various small sized product.
The utility model content
At above the deficiencies in the prior art and defective, the purpose of this utility model is to provide a kind of oval polymer Li-ion battery.
The purpose of this utility model is achieved by the following technical solution:
A kind of oval polymer Li-ion battery, the positive plate that comprise shell, is provided with lug and the negative plate that is provided with lug.Described shell is oval cylinder, and this positive plate and negative plate are located in this ellipse cylinder, and two lugs are located at the two ends of oval cylinder respectively.
As optimal technical scheme of the present utility model, described oval cylinder is formed by the aluminum plastic film doubling with two semiellipse grooves.
As optimal technical scheme of the present utility model, the size of described two semiellipse grooves, shape unanimity.
As optimal technical scheme of the present utility model, described aluminum plastic film is one deck, and its thickness is 0.113～0.117mm.
Compared with prior art, the battery case in the utility model is oval cylinder, has bigger volume space, and is assemblied in the electronic product, can not occupy the very big position of product, is convenient to the structural design of product.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is the structural representation of a kind of oval polymer Li-ion battery of the utility model.
Fig. 2 is the shell mechanism schematic diagram of a kind of oval polymer Li-ion battery of the utility model.
Embodiment
See also Fig. 1 and Fig. 2, be respectively the structural representation and the shell mechanism schematic diagram of a kind of oval polymer Li-ion battery of the utility model.
This ellipse polymer Li-ion battery comprises shell 101, positive plate (figure does not show) and negative plate (figure does not show), is respectively equipped with lug 102,103 on this positive and negative plate.Described shell 101 adopts the aluminum plastic film material, this aluminum plastic film is provided with the semiellipse groove 104 of two sizes, shape unanimity, this aluminum plastic film doubling, two halves oval recess 104 fits into a complete oval cylinder, positive and negative plate is packaged in this ellipse cylinder, two lugs 102,103 stretch out as connecting terminal in shell 101, are located at the two ends of oval cylinder respectively.Wherein, described aluminum plastic film is one deck, and its thickness is 0.113～0.117mm.
The polymer Li-ion battery of this kind structure, its shell 101 is oval cylinder, has bigger volume space, and is assemblied in the electronic product, can not occupy the very big position of product, is convenient to the structural design of product.
The above is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Every equivalence of doing according to the utility model changes and revises, and is all covered by the scope of the utility model claims.
